Closing your corporation
the right way.

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

When a business has run its course — you are retiring, the venture wound down, you moved your work into a different company, or the partnership simply ended — there is a quiet question that comes next: what do you actually do with the corporation? A lot of owners assume the answer is "nothing." You stop invoicing, stop filing, let the bank account sit empty, and figure the company will just fade away. It will not. A corporation is a separate legal person, and it keeps existing until someone formally ends it.

Closing a corporation the right way is called voluntary dissolution, and it runs in five stages: you wind the business up and settle or provide for its debts, you deal with the property that is left and file articles of dissolution to end the corporation's legal existence, you file the final T2 and the other final returns for the tax year that ends on the dissolution date, you get those returns assessed and obtain a CRA clearance certificate, and then you close the CRA accounts and keep the records. None of the individual steps is hard. What trips people up is that the corporate steps and the tax steps depend on each other, and not in the direction most owners assume.

Below I will walk through why simply abandoning a corporation is a mistake, the difference between dissolving voluntarily and being dissolved by the government, the step-by-step process and where the corporate and tax timelines collide, how to deal with what is left, the final tax filings and the CRA clearance certificate, and the exposure that lingers if you skip steps. This is general information, not advice on your specific company — and dissolution is genuinely a job for a lawyer and an accountant working together — but it will give you a clear, accurate picture of what closing a corporation actually involves.

Can I just stop using my corporation and let it fade away?

No — a corporation is a separate legal person that stays alive, with all its obligations intact, until it is formally dissolved, so simply abandoning it leaves the debts, taxes, and director exposure behind. The single most common thing I hear is some version of: "I'm done with the business, so I'll just stop filing and it'll go away." I understand the instinct — the company feels finished, so why keep spending time and money on it? But a corporation does not work that way. It is a separate legal person, and it stays alive, with all its obligations intact, until it is formally dissolved.

Here is what actually happens when you abandon a corporation. It keeps existing, but it stops meeting its obligations — annual returns go unfiled, tax filings lapse. Eventually the government can step in and dissolve or cancel the company involuntarily for failing to file. That sounds like the outcome you wanted, except it is not a clean ending. An involuntary dissolution leaves loose ends behind: unpaid taxes that never got resolved, liabilities that were never properly dealt with, and — this is the part that bites — personal exposure for the directors on amounts the company owed.

I have seen this play out years later. A client thinks a company they walked away from in, say, 2019 is long gone, and then a tax issue, an old creditor, or a forgotten obligation surfaces and they discover the corporation was never properly closed — and that they, as a director, are on the hook for something they assumed had evaporated. The cost of cleaning that up dwarfs the cost of having dissolved the company properly in the first place.

The clean route is a voluntary dissolution. You deliberately wind the company down, deal with what is left, file the paperwork that formally ends its existence, and then close out the corporation's tax position properly. It takes a bit of effort up front, but it closes the door, and it closes it on your terms and on your timetable.

What is the difference between voluntary dissolution and being dissolved by the government?

Voluntary dissolution is the orderly wind-down you control: authorize it, settle or provide for the debts, deal with the remaining property, file the articles, and then complete the final tax filings and get clearance. Involuntary dissolution is an enforcement step the government takes for unfiled returns, and it ends the registration without resolving the company's affairs. It is worth being precise about the two very different ways a corporation can come to an end, because people use the word "dissolved" for both and they are not the same thing at all.

Voluntary dissolution is the orderly wind-down of a corporation that is still in good standing. The owners decide to close the company, so they authorize it, settle or provide for the debts, deal with any remaining assets, file articles of dissolution, and then file the final returns and obtain a CRA clearance certificate. You control the timing, and you can plan the corporate and tax steps around each other. This is the route you want.

Involuntary dissolution (sometimes called cancellation) is what the government can do to a corporation that stops meeting its obligations — most commonly, that fails to file its returns. It is not a service you are receiving; it is an enforcement step. And crucially, it does nothing to resolve the company's actual affairs. The unpaid taxes are still unpaid. The liabilities are still there. The directors' exposure has not gone anywhere. The company's legal status has changed, but the mess underneath it has not been cleaned up.

There is a partial safety valve here, though a narrower one than people assume. Where the Director dissolved a corporation by order, an interested person can apply to have it revived, generally within 20 years, and on revival the corporation is treated as though it had never been dissolved. That is the route for an involuntary dissolution. It is not generally available for an Ontario corporation that was voluntarily dissolved by filing articles of dissolution, so if a forgotten asset or a late claim surfaces after a voluntary wind-up you may be dealing with the province rather than making a simple filing. Real property owned by a dissolved Ontario corporation forfeits to the Crown, and recovering it means applying to the ministry for relief from forfeiture; for property that is not forfeited corporate property, such as cash or shares, officers and shareholders may be able to apply to the Office of the Public Guardian and Trustee instead. Federal corporations are treated differently again: the federal Act lets an interested person apply to revive a corporation dissolved under its liquidation and dissolution provisions, including a voluntary one. Either way, revival is a remedy for surprises, not a substitute for doing the job properly. Relying on being able to bring a company back is not a plan; winding it down correctly the first time is.

Is an involuntarily dissolved corporation really "closed"?

Not in the way that matters to you — its registered status may say dissolved, but the unpaid taxes, unsettled debts, and director exposure it carried do not disappear with the registration. Its registered status may say dissolved, but the obligations it carried — unpaid taxes, unsettled debts, director exposure — do not disappear with the registration. That is the whole problem with treating an involuntary dissolution as a finish line: it ends the paperwork without ending the liability. A voluntary dissolution, planned properly and carried through to the final returns and the clearance certificate, is what actually resolves those obligations so nothing is left to come back on you.

What are the steps to dissolve a corporation in Ontario?

You authorize the dissolution, wind the business up and settle or provide for its debts, deal with the remaining property, file the articles of dissolution, then file the final T2 and the other final returns for the tax year ending on the dissolution date, get those returns assessed and apply for a CRA clearance certificate, release anything you held back, and finally close the CRA program accounts and keep the records. Those eight steps follow the five stages of a dissolution: the wind-up, the dissolution filing, the final tax filings, the CRA assessment and clearance, and the clean-up. Treat it as the normal shape of a voluntary dissolution rather than a rule about order that applies to every company, because the corporate steps and the tax steps overlap and some of the timing is a judgment call. Work through it with your accountant before you file anything.

1. Authorize the dissolution. The shareholders have to approve closing the company. The usual route is a special resolution, meaning at least two-thirds of the votes cast at a meeting called for the purpose, and the written consent of all shareholders entitled to vote works too; a corporation that never commenced business and never issued shares can be dissolved by its incorporators instead. Record the resolution properly in the corporation's minute book. It authorizes everything that follows, and the CRA will ask for a copy of it later.
2. Wind up the business. Collect what is owed to the company, finish or cancel its contracts, and pay or settle what it owes: suppliers, lenders, and the tax authorities, including corporate income tax, HST, and payroll source deductions. If you had employees, deal with outstanding wages and vacation pay and issue their Records of Employment. Keep filing the ordinary returns that come due while you are winding up. The final ones come later. If the corporation ever owned land in Ontario, it has to be off title before the province will endorse the articles.
3. Deal with the remaining property, and hold back for tax. Ontario's Business Corporations Act expects the corporation's debts to be satisfied or duly provided for and its remaining property to be dealt with before the articles are filed, and anything the corporation still owns on the date of dissolution forfeits to the Crown. In practice that means distributing most of what is left and retaining a realistic amount for the tax bill that has not been calculated yet, held outside the corporation by whoever is running the wind-up. Doing it that way is what lets the articles say honestly both that the tax liability has been "duly provided for" and that the corporation has no property left to distribute. Be clear-eyed about the basis for it, though: the Income Tax Act on its face requires a clearance certificate before distributing any property. The allowance for distributing early as long as enough is kept back is the CRA's published administrative position, not a statutory safe harbour. Sizing that holdback is the single most important conversation to have with your accountant.
4. File the articles of dissolution. For an Ontario corporation you file through the Ontario Business Registry; a federal corporation files with Corporations Canada. Ontario dissolutions also need consent from the Ministry of Finance, which the ministry provides electronically and allows itself up to 30 business days to do. The certificate endorsed on the articles is the certificate of dissolution, and the date on it is the corporation's legal dissolution date. That date drives everything that follows, and it is worth knowing that you have some say in it: the certificate is dated as of the day the Director receives a complete filing, or a later date you specify if the Director accepts it. Picking a clean date, a month end for instance, can make the final stub period much easier for your accountant.
5. File the final T2 and the other final returns. The corporation's final tax year ends on the date of dissolution shown on the articles, which is why this step cannot come earlier. The final T2 is due six months after that year end, with any balance owing due sooner, generally two or three months after it. A final HST return, final payroll filings and T4 slips, and any T5s go in as well. This is squarely your accountant's job, and it is the part of a dissolution where mistakes are most expensive.
6. Get the returns assessed, then apply for the clearance certificate. Clearance is not something you request up front. The CRA issues it only once the required returns have been filed and assessed and the balances paid or secured, and the application on Form TX19 has to include the notice of assessment for the final T2, the resolution authorizing the dissolution, and a statement of how the assets were distributed. If the company was registered for HST there is a separate GST/HST clearance certificate on Form GST352.
7. Release the holdback. Once the clearance certificate arrives, pay out what you kept back and complete the distribution promptly. Handing out everything without a clearance certificate and without retaining enough for the tax bill is what puts the person running the wind-up personally on the hook for the shortfall.
8. Close the CRA accounts and keep the records. File Form RC145 with a copy of the articles of dissolution to close the business number program accounts for income tax, HST, and payroll. Skip it and the CRA keeps treating the corporation as existing and keeps expecting returns. Then keep the records. The prescribed retention period for a dissolved corporation is two years after the dissolution date, and that covers the minute books, the share register and the general ledger as well as the ordinary books and vouchers. Two years is the tax floor, not a target: limitation periods, an outstanding objection or appeal, and other statutes can all run longer, so in practice most advisers keep the whole file well beyond it.

There is a genuine tension inside that list, and it is worth naming rather than papering over. The Business Corporations Act wants the corporation wound up, its liabilities satisfied or provided for, and its remaining property dealt with before the articles of dissolution are filed. The Income Tax Act runs the other way: the final T2 covers a tax year that ends on the legal dissolution date, so it cannot be completed until the articles have been filed and the certificate issued. And the clearance certificate, which is what makes a distribution safe, comes later still, because the application needs the notice of assessment for that final return. Read strictly, each step waits on another one.

What resolves it in practice is the holdback in step 3. You do the corporate wind-up honestly, distribute the bulk of what is left, and retain enough outside the corporation to cover the tax that is still coming. The CRA's clearance circular says in terms that you do not need a certificate before every distribution as long as you keep enough property to pay what may be owed, and the money sitting outside the corporation is also what keeps it clear of the forfeiture rule.

I want to be straight about how solid that footing is, because it is the hinge of the whole exercise. The statute itself is unconditional: it says the legal representative shall obtain a certificate before distributing any property, and the CRA's own T2 guide states the strict version, that only after you receive the certificate can you begin distributing. The keep-enough-back allowance comes from the CRA's clearance circular, which is published administrative policy rather than a rule the courts are bound by. It is how these are handled in practice, and it is the only reading that can be squared with what the articles of dissolution require you to state, but it is a judgment call with residual risk attached, and the risk sits with whoever signs off on the distribution. The circular also acknowledges the circularity directly and invites you to contact your tax services office to make alternative arrangements where it bites. If your wind-up is at all substantial, that call is worth making rather than assuming.

That is the coordination point between the legal side and the accounting side, and it is the thing most worth agreeing on before anyone files anything. It is also why I am wary of checklists that present a single rigid order as though it applied to every company. The shape is consistent; the timing is not.

Why can the final T2 not be filed before the articles of dissolution?

Because the corporation's final tax year ends on the legal dissolution date, and that date does not exist until the articles of dissolution have been filed and the certificate of dissolution issued. The CRA's T2 guide is explicit about it. You answer yes to the final-return question only if you have already permanently dissolved the corporation with the incorporating authority and you are filing for a tax year ending on the date of dissolution, and the guide tells you that you will find that date on the articles of dissolution.

So a return filed before the articles is not the final return. It is an ordinary return for an earlier period, and a genuine final T2 still has to follow. This surprises people, because the instinct is to clear the taxes first and file the paperwork last. Keep filing the ordinary returns that fall due while you are winding up, by all means. But the closing return, the one that reports the last stub period and lets the CRA assess the corporation for the final time, comes after the dissolution rather than before it.

How long does dissolving a corporation take?

Plan for months rather than weeks: the Ministry of Finance allows itself up to 30 business days to consent to an Ontario dissolution, the final T2 is due six months after the dissolution date, and the CRA's service standard for a clearance certificate is 120 calendar days after the request. The filing itself is the fast part. ServiceOntario processes articles of dissolution in about two business days online, but Ontario dissolutions also need the Ministry of Finance consent, which adds a wait you do not control.

The tax side sets the real pace. Your accountant cannot finish the final T2 until the dissolution date exists, the return is due within six months of that date, the CRA then has to assess it, and only after the assessment can the clearance certificate be requested. The CRA aims to issue clearance within 120 calendar days of the request, and days spent under audit do not count toward that. A simple company with no employees, no HST, and nothing left to distribute moves faster; one with staff, HST, and assets does not. Build the timeline backwards from the clearance certificate rather than forwards from the filing, and do not skip the clearance step just to go faster.

What taxes do I have to deal with when closing a corporation?

During the wind-up you pay or provide for the corporation's tax debts; after the dissolution you file a final T2 for the tax year ending on the dissolution date, a final HST return, and the required T4 and T5 slips; once those are assessed you obtain a CRA clearance certificate; and only then do you close the program accounts. This is the area where a sloppy wind-down turns into a personal problem for the people who ran the company, so it is worth slowing down on.

First, the final returns. Closing a corporation does not mean you simply stop filing. It means you file a final set of returns: a final T2 corporate income tax return, a final HST return if the company was registered, and any T4 slips for employees and T5 slips for dividends that the year requires. The timing is what people get wrong. The final T2 covers a tax year that ends on the date of dissolution, which you take from the articles of dissolution, so it is prepared after the dissolution rather than before it. It is due six months after that year end, and any balance owing is due sooner, generally two or three months after it. Your accountant prepares and files all of this, and it is worth agreeing on the timing with them before the articles go in rather than after.

Second, the CRA clearance certificate. A clearance certificate is the Canada Revenue Agency's confirmation that everything the corporation owes has been paid or secured. You request it on Form TX19 after the final returns have been filed and assessed, because the application has to include the notice of assessment for the final T2, together with the resolution authorizing the dissolution and a statement of how the assets were distributed. If the company was registered for HST, there is a separate GST/HST clearance certificate on Form GST352.

Here is the reasoning, and it is the most important paragraph in this article. Whoever administers the wind-up and hands out the corporation's property is treated by the Income Tax Act as its legal representative, and a legal representative who distributes property without a clearance certificate is personally liable for what the corporation turns out to owe, up to the value of what was distributed. In a voluntary dissolution there is usually no formally appointed liquidator, so that role lands on a director or officer. The same requirement exists separately for HST, with its own certificate and its own personal liability for the representative who distributes without one. The CRA's clearance circular does allow distributions before clearance on one condition, that enough property is kept back to cover the liability, and that condition is the whole ballgame. But note that this is administrative policy: the legislation itself says the certificate comes first, full stop. Distribute everything and confirm later and you have taken on a risk you did not need to; distribute with a sensible holdback and you are relying on a well-established CRA practice rather than on the words of the statute. Your accountant should be the one sizing that call.

Third, close the program accounts. This one genuinely does come last. Once the corporation has been dissolved and the final returns are filed and paid, send the CRA Form RC145 with a copy of the articles of dissolution to close the income tax, HST, and payroll program accounts. If you skip it, the CRA keeps treating the corporation as existing and keeps expecting returns from a company that no longer exists.

What happens to the company's assets when it dissolves?

Creditors and the tax authorities come first, and whatever is genuinely left over goes to the shareholders, usually in proportion to their shareholdings; under Ontario law that distribution generally happens before the articles of dissolution are filed, with a holdback retained for the tax bill still to come. This is the step where the corporate rules and the tax rules pull in different directions, so it repays a little care.

The corporate rule comes from the articles of dissolution themselves. Before the province will endorse them, the corporation has to state that it has no debts, obligations or liabilities, or that they have been duly provided for, or that its creditors consent; and that after satisfying its creditors it either has no property left to distribute or has distributed what remained rateably among its shareholders according to their rights. There is a hard edge to this: any property the corporation still owns on the date of dissolution forfeits to the Crown. Leaving the money sitting in the company's bank account so it is there for the tax bill is therefore not the safe option it sounds like.

The tax rule pulls the other way, because clearance cannot be obtained until well after the dissolution. The usual reconciliation is a holdback: distribute the bulk of the remaining property before the articles are filed, and retain a realistic amount for the final tax bill outside the corporation, held by whoever is running the wind-up, often in a lawyer's trust account. That satisfies the corporate requirement, meets the CRA's condition for distributing before clearance, and keeps the money clear of the forfeiture rule. How much to hold back is an accounting judgment rather than a legal one, so size it with your accountant and err high.

The old shorthand, debts first, distribution last, is still the right instinct. It just needs one refinement: the tax authorities have first claim on the company's money, and because the final tax number is not known until after the dissolution, "last" means after clearance for the holdback, not after every dollar has been confirmed before the articles are filed. Reverse the instinct entirely, pay the owners out and only then find out the company owed money, and you have created exactly the personal-liability problem the clearance certificate is designed to prevent.

One more thing worth knowing: dissolving does not put the money out of reach. Under the Business Corporations Act, a shareholder who received property on the dissolution can be sued for it, up to the amount they received, by someone with a claim against the dissolved corporation. A distribution is not a clean break for the shareholders any more than it is for the directors.

A practical note for companies with more than one owner: the wind-down is also the moment to make sure everyone agrees on what the remaining assets are and how they get divided, before any money moves. If your corporation has a shareholders' agreement, it may set out how a wind-down and the division of assets are handled, so it is worth pulling out and reading. Sorting this out on the way in avoids a dispute on the way out — and a dissolution that turns into a falling-out is a bad way to end a business that everyone was once proud of.

One more situation to flag, because it changes everything: this orderly distribution assumes the corporation can actually pay its debts in full. If it cannot — if the company is insolvent — you are in a different and more serious scenario, and you should get advice before distributing anything or filing anything. Closing a solvent company and dealing with an insolvent one are not the same exercise.

What can directors be personally liable for if you skip steps?

Three separate exposures: unremitted payroll source deductions and HST, which reach directors directly but carry a due diligence defence and a two-year limit; the corporation's unpaid tax where its property was distributed without a clearance certificate and without enough kept back, which reaches whoever ran the wind-up; and up to six months' unpaid employee wages plus twelve months' vacation pay. I keep coming back to personal exposure because it is the real reason to do this properly. The corporate shield is real, but it is not absolute, and a botched dissolution is one of the surest ways to find its limits.

The first exposure exists whether or not you dissolve. Directors can be assessed personally for payroll source deductions and HST that the corporation failed to remit. Winding the company up does not clear that, and neither does walking away and letting the government dissolve it. Two limits are worth knowing, because they are real and people rarely hear about them. There is a due diligence defence: a director is not liable if they exercised the care, diligence and skill that a reasonably prudent person would have exercised in comparable circumstances to prevent the failure. And there is a two-year limit: the CRA cannot come after you more than two years after you last ceased to be a director. Both apply to source deductions and to HST. Neither is a reason to be casual, and both are fact-heavy enough that you would want advice before relying on either.

The second is specific to the wind-down, and it is the one people walk into. Whoever administers the wind-up and distributes the corporation's property is its legal representative for tax purposes, and a legal representative who distributes without a clearance certificate, and without retaining enough to cover what the corporation may owe, is personally liable for the shortfall up to the value of what was handed out. In a small company that person is almost always a director or officer. The distribution is what does it, which is why the size and the handling of the holdback matter so much.

There is also exposure around employees. Under the Business Corporations Act directors are jointly and severally liable to employees for up to six months' wages that became payable while they were directors, and up to twelve months' accrued vacation pay. It is bounded in another way too: a director is liable only where the corporation itself has been sued and execution has come back unsatisfied, or the corporation has gone into liquidation, winding up or bankruptcy and the claim has been proved. Real exposure, then, but not open-ended, and it is why winding up the business includes dealing with employees properly and issuing their Records of Employment rather than just turning off the lights.

And then there is the broad category of loose ends from an abandoned company: obligations that were never resolved because the corporation was simply left to lapse. Those do not disappear with an involuntary dissolution; they sit there, attached to the people who were responsible for the company, waiting to surface. The whole point of a voluntary dissolution, done properly and carried through to clearance, is to resolve all of it deliberately so there is nothing left to come back on you. If you want a sense of how directors' personal exposure works more generally — including while a company is still operating — our guide to what happens after you incorporate in Ontario covers the duties and liabilities that come with the role.

What are the most common mistakes when dissolving a corporation?

The costliest mistakes are abandoning the company instead of dissolving it, filing the articles before the wind-up is actually finished, distributing everything and keeping nothing back for tax, treating the clearance certificate as optional, assuming the final T2 comes first, not authorizing the dissolution properly, and destroying the records too early. Most dissolution problems are not exotic. They trace back to skipping a step, or to running the corporate steps and the tax steps on separate tracks.

Abandoning the company instead of dissolving it. The big one. Walking away and letting the corporation lapse feels like closing it, but it leaves the obligations, and your exposure, fully intact. An involuntary dissolution by the government is not the clean ending it looks like.

Filing the articles before the wind-up is real. The articles of dissolution contain statements about the corporation's debts, its property, and the absence of pending proceedings. Signing them when the wind-up is only half done is not a formality; it is a false statement about the state of the company, and it can leave property to forfeit to the Crown on the dissolution date.

Distributing everything and keeping nothing back. The single most dangerous sequencing error, because it is the one that converts a corporate tax debt into a personal one. The final tax bill is not knowable until after the dissolution, so a holdback is not caution, it is the mechanism that makes the rest of the sequence work.

Treating the clearance certificate as optional paperwork. It is the confirmation that lets you release the holdback safely. Skipping it means paying out on a guess, and it is the person who authorized the payment who wears the difference.

Assuming the final T2 comes first. It cannot. The corporation's final tax year ends on the dissolution date, and that date does not exist until the articles have been filed and the certificate issued. Ordinary returns keep going in during the wind-up; the closing return follows the dissolution.

Not authorizing the dissolution properly. Forgetting that the shareholders have to authorize a dissolution, or never recording it, leaves the wind-down standing on nothing. The resolution is the foundation, and the CRA will want a copy of it at the clearance stage. Record it in the minute book.

Destroying the records too early. A dissolved company can still be asked questions years later. The prescribed retention period for a dissolved corporation is two years after the dissolution date, covering the minute books and share register as well as the ordinary books and vouchers, but that is a tax floor rather than a target. Limitation periods and any outstanding objection or appeal can run well past it. Keeping the whole file longer costs almost nothing and has saved more than one former director an unpleasant afternoon.

Do I need a lawyer or accountant to dissolve my corporation?

It is not legally required, but I strongly recommend both, and recommend that they actually talk to each other: the accountant handles the tax side where the personal-liability risk sits, and a lawyer makes sure the wind-down is authorized, the property is dealt with correctly, and the articles are filed and recorded properly. This is one where I genuinely recommend it, and not as a sales pitch. The value is specifically in coordinating two sets of steps that depend on each other, which is exactly the thing that is easy to get wrong on your own.

The division of labour is clean. Your accountant handles the tax side: the final T2 and HST returns, the slips, closing the program accounts, and obtaining the clearance certificate. That is the part with the most personal-liability risk, and it is firmly in their lane. A business lawyer makes sure the dissolution is properly authorized and recorded, that the remaining property is dealt with the way the articles of dissolution require, that the articles are filed correctly, and that the corporate records are in order. The part worth paying for is the coordination: the corporate steps and the tax steps depend on each other, and the holdback sits right on the seam between them. If your company's minute book and corporate maintenance have drifted over the years — which is common — that often needs to be tidied up as part of a clean wind-down too. A dissolution looks simple on the form, and the form is simple; it is everything around the form that benefits from a steady hand.

How much does it cost to dissolve a corporation in Ontario?

The government filing itself is inexpensive, often around $25 online to file articles of dissolution through the Ontario Business Registry, but the real cost is the professional work around the wind-down and the final tax filings. Filing the articles of dissolution for an Ontario corporation through the Ontario Business Registry is generally inexpensive, often around $25 online, though fees can change, so confirm the current amount when you file. There is no separate charge for the Ministry of Finance consent that Ontario dissolutions require; it costs time rather than money.

The real cost of a dissolution is the work around it: the accountant's time on the final returns and the clearance certificate, and the legal work on authorizing the wind-down, dealing with the remaining property, and filing the articles. Compared to the cost of cleaning up an abandoned company years later, doing it properly is almost always the cheaper path. If you are weighing what professional help runs more broadly, our guide on how much a business lawyer costs in Toronto gives a sense of the range.

Should I dissolve my corporation or sell it instead?

Dissolve when the business genuinely has no ongoing value or you are simply retiring a vehicle you no longer use — but if it still has customers, contracts, a brand, or clean books, a sale may capture value that winding down would leave on the table. If the business still has value — customers, contracts, a brand, clean books — winding it down may be leaving money on the table that a sale would capture. Dissolution is the right answer when the business genuinely has no ongoing value to anyone, or when you are simply retiring a vehicle you no longer use. But if there is a real business here, it may be worth talking to a lawyer who handles business sales first, and our guide to planning your business exit walks through how to think about that choice. A corporation you built is worth a moment's thought before you close the door on it.

Key takeaways

• Do not just abandon it. A corporation keeps existing until it is formally dissolved; walking away can lead to an involuntary dissolution that leaves unpaid taxes, unresolved liabilities, and director exposure intact.
• Wind up first, then file. The shareholders authorize the dissolution, you settle or duly provide for the debts, and you deal with the remaining property before the articles of dissolution go in. Anything the corporation still owns on the dissolution date forfeits to the Crown.
• The final T2 comes after the articles, not before. The corporation's final tax year ends on the legal dissolution date shown on the articles of dissolution, so the closing return cannot be prepared until that date exists. It is due six months after that year end.
• Clearance comes after assessment, and the holdback is what bridges the gap. Form TX19 needs the notice of assessment for the final T2, so clearance is months away when the articles are filed. The CRA's clearance circular permits distributing before clearance as long as enough property is kept back to cover what may be owed, though the statute itself says the certificate comes first, so treat the holdback as well-established practice rather than a guarantee. Retain a realistic amount outside the corporation and release it once the certificate arrives.
• Close the accounts and keep the records. File Form RC145 with a copy of the articles of dissolution to close the CRA program accounts. The prescribed retention period for a dissolved corporation is two years after the dissolution date, but that is a tax floor, and limitation periods and any live objection or appeal can run longer.
• Coordinate, do not follow a rigid checklist. The corporate steps and the tax steps depend on each other, and the timing is a judgment call for each company. Get your lawyer and your accountant working from the same plan before anything is filed.

Frequently asked questions

How do I dissolve a corporation in Ontario?

You dissolve an Ontario corporation through a voluntary dissolution, and it runs in five stages. First you wind the corporation up: the shareholders authorize the dissolution, you collect what is owed to the company, deal with employees, and pay or provide for the debts. Second, you deal with the remaining property and file articles of dissolution through the Ontario Business Registry, which produces the certificate of dissolution and the legal dissolution date. Third, you file the final T2 and the other final returns for the tax year that ends on that dissolution date. Fourth, once the CRA assesses those returns you apply for a tax clearance certificate and release anything you held back for tax. Fifth, you close the CRA program accounts and keep the records. The corporate steps and the tax steps overlap, so the timing is something to plan with your accountant rather than a fixed checklist.

Do I file the final T2 before or after the articles of dissolution?

After. This trips up almost everyone, because the instinct is to clear the taxes first and do the paperwork last. The corporation's final tax year ends on the legal dissolution date, and that date does not exist until the articles of dissolution have been filed and the certificate of dissolution issued. The CRA's own T2 guide says you answer yes to the final-return question only if the corporation has already been dissolved and you are filing for a tax year ending on the date of dissolution, and that you will find that date on the articles of dissolution. Keep filing the ordinary returns that come due while you are winding up. The closing return comes after the dissolution.

Can I just stop using my corporation?

You can, but it is a mistake. If a corporation simply stops filing, the government can eventually dissolve or cancel it involuntarily, but that leaves loose ends behind: unpaid taxes, unresolved liabilities, and personal exposure for the directors. A walked-away corporation is not a closed one. The clean route is a voluntary dissolution, where you deliberately wind the company down, deal with its property, file the articles, clear its taxes, and close the accounts. It costs a little effort now but avoids problems that can surface years later, often at the worst possible time.

What is voluntary dissolution?

Voluntary dissolution is the deliberate, orderly process of closing a corporation that is still in good standing. The owners decide to wind the company down, so they authorize it, settle or provide for the company's debts, deal with the remaining property, file articles of dissolution to end the corporation's legal existence, and then complete the final tax filings and obtain a CRA clearance certificate. It is the opposite of being involuntarily dissolved by the government for failing to file. Voluntary dissolution is the route I recommend in almost every case, because it lets you plan the corporate and tax steps together instead of discovering them out of order.

Do I need shareholder approval to dissolve?

Yes. A voluntary dissolution has to be authorized by the shareholders. The usual route is a special resolution, which means at least two-thirds of the votes cast at a meeting called for the purpose; the written consent of all shareholders entitled to vote works too. A corporation that has never commenced business and never issued shares can be dissolved by its incorporators instead. The directors typically recommend the dissolution, but the shareholders are the ones who authorize it, and the resolution should be properly recorded in the minute book, because the CRA will later ask for a copy of it when you apply for the clearance certificate. If you have co-owners, this is also the moment to confirm everyone agrees on the wind-down and on how any remaining assets get divided.

What taxes do I have to deal with when closing a corporation?

During the wind-up you pay or provide for everything the corporation owes, including corporate income tax, HST, and payroll source deductions, plus outstanding employee wages and vacation pay. The final filings come after the dissolution: a final T2 for the tax year ending on the dissolution date, a final HST return, and any required T4 and T5 slips. The final T2 is due six months after that year end, and any balance owing sooner, generally two or three months after it. Once those returns are assessed you apply for a CRA clearance certificate, and only then do you close the program accounts. Tax is the part of a dissolution most likely to create personal exposure, so handle the timing with your accountant.

What is a CRA tax clearance certificate and do I need one?

A CRA tax clearance certificate confirms that everything the corporation owes has been paid or secured. You request it on Form TX19 after the final returns have been filed and assessed, because the application has to include the notice of assessment for the final T2, along with the resolution authorizing the dissolution and a statement of how the assets were distributed. If the company was registered for HST there is a separate GST/HST clearance certificate on Form GST352. Why it matters: whoever administers the wind-up and distributes the corporation's property is treated as its legal representative, and distributing without a clearance certificate makes that person personally liable for what the corporation turns out to owe, up to the value of what was handed out. The CRA's clearance circular does allow distributions before clearance if enough property is kept back to cover the liability, and that is how most wind-ups are handled, but be aware the legislation itself says the certificate comes first, so the holdback is well-established practice rather than a statutory guarantee. There is an equivalent requirement and an equivalent personal liability on the HST side. Your accountant normally obtains the certificate.

What are articles of dissolution?

Articles of dissolution are the formal filing that ends the corporation's legal existence. For an Ontario corporation you file them with the province through the Ontario Business Registry; a federally incorporated company files with Corporations Canada instead. They come after the wind-up, because the articles have to state that the corporation has no debts, obligations or liabilities or that they have been duly provided for, and that after satisfying its creditors it has either nothing left to distribute or has distributed what remained among its shareholders. They come before the final tax filings, because the tax year ends on the dissolution date shown on the certificate. Ontario dissolutions also need consent from the Ministry of Finance, which the ministry allows itself up to 30 business days to provide. The filing fee is modest, often around $25 online, though fees can change.

What happens to the company's assets and debts when it dissolves?

The debts come first. Before anything is distributed, the corporation has to pay, settle, or duly provide for what it owes: suppliers, lenders, employees, and the tax authorities. Only what is genuinely left over goes to the shareholders, usually in proportion to their shareholdings, and under Ontario law that distribution generally has to happen before the articles of dissolution are filed. Anything the corporation still owns on the date of dissolution forfeits to the Crown, so leaving money in the company account for the tax bill is not the safe option it sounds like. The usual answer is a holdback: distribute the bulk, and keep a realistic amount for the final tax bill outside the corporation until the clearance certificate arrives. That rests on the CRA's published clearance policy rather than on the words of the statute, so size it with your accountant. And note that a shareholder who received property on the dissolution can still be sued for it, up to the amount received. If the corporation cannot pay its debts in full, that is a different and more serious situation, and you should get advice before doing anything.

Can a dissolved corporation be brought back (revived)?

It depends on how it was dissolved. Under the Ontario Business Corporations Act, revival is available for a corporation that was dissolved by the Director's order, which is the involuntary route, on application within 20 years. A corporation that was voluntarily dissolved by filing articles of dissolution generally cannot be revived that way. If a forgotten asset surfaces afterwards you are dealing with the province instead: real property forfeits to the Crown and recovering it means applying for relief from forfeiture, while property that is not forfeited corporate property, such as cash or shares, may be recoverable through an application to the Office of the Public Guardian and Trustee. Federal corporations are treated differently again, and the federal Act does allow revival after a voluntary dissolution. Either way, revival is a remedy for surprises, not a plan. It is far better to wind the company down properly the first time, and if you think you may need to revive a corporation, get advice.

Do I need a lawyer or accountant to dissolve my corporation?

It is not legally required, but I strongly recommend working with both, and specifically recommend that they talk to each other. The tax side, meaning the final returns, HST, payroll, and the clearance certificate, is squarely your accountant's domain, and getting it wrong is where personal exposure comes from. A lawyer makes sure the dissolution is properly authorized and recorded, that the remaining property is dealt with the way the articles of dissolution require, that the articles are filed correctly, and that the records are kept. The hard part of a dissolution is not any individual step. It is that the corporate steps and the tax steps depend on each other, and coordinating them is exactly what professional help gets right.

Final thoughts

Closing a corporation is one of those tasks that looks trivial and quietly is not. The forms are short, the fees are modest, and the temptation to just let the company lapse is strong, which is exactly why so many people end up with an unresolved corporation hanging over them years after they thought they were done. The difference between a problem and a clean ending is not effort. It is coordination. Authorize the dissolution properly, settle or provide for the debts, deal with the remaining property and hold back for tax, file the articles, then file the final T2 for the year that ends on the dissolution date, get it assessed, obtain clearance, release the holdback, and close the accounts. Run the legal side and the tax side from one plan and there is nothing left to come back on you.

That is also why I rarely tell someone to dissolve a company entirely on their own. The wind-down touches tax, employees, asset distribution, and personal liability all at once, and the pieces have to be timed against each other. The cost of an accountant and a lawyer to do it cleanly is small next to the cost of unwinding a botched dissolution. The same care that goes into setting a company up well with an incorporation lawyer is worth applying when you take it down. Whether you incorporated provincially or federally — and if you are not sure which you are, federal vs. Ontario incorporation explains the difference, because it determines where you file the articles of dissolution and which revival rules apply afterwards — the goal is the same: end the corporation deliberately, not by neglect.
