Do you need a
holding company?

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

"Should I set up a holding company?" comes up constantly once a business starts doing well. A client hears about a holdco from a friend, a banker, or an accountant, and suddenly they are convinced they need one. Sometimes they are right. Just as often, they do not need one yet — and a holding company set up too early is an extra corporation to feed every year for no real benefit.

A holding company is genuinely useful, but only for the right business at the right time. It can move surplus cash beyond the reach of your operating company's creditors, let profits flow up tax-efficiently, support estate planning and succession, hold more than one business under one roof, and help preserve a valuable tax exemption on a future sale. None of that is automatic, and all of it comes at the cost of running two corporations instead of one.

Below I will explain what a holding company actually is, the real reasons people use one, when it is and is not worth the cost, and the catch that quietly undoes the whole structure if you ignore it. One thing up front: this is tax-adjacent, and I am a business lawyer, not your accountant. Anywhere the tax matters, I will keep it general and point you to your accountant — because the exact numbers, and whether a holdco helps yours, have to be modelled, not guessed.

What a holding company actually is

A holding company — almost everyone calls it a holdco — is a corporation that holds the shares of your operating company, and often the valuable assets above it, instead of running the business itself. Your operating company, the opco, is the one that earns revenue, signs the customer contracts, employs people, and carries the commercial risk. The holdco sits on top of it, owning opco's shares and holding surplus cash, investments, or property you want kept separate from the day-to-day business.

It is worth being clear that a holdco is not a special legal species. It is an ordinary corporation — incorporated the same way any company is, under the same statutes I describe in my guide to how to incorporate a business in Ontario. The only difference is its job: it holds rather than operates. You can picture it as a simple two-storey structure. Opco is downstairs, doing the work and taking the risk. Holdco is upstairs, owning opco and safeguarding whatever has been sent up to it.

That picture — opco over the risk, holdco over the value — is the whole idea, and almost every benefit of a holding company flows from it. Keep it in mind, because the rest of this guide is really just an explanation of why you might want to move things from the downstairs floor to the upstairs one.

How is a holdco different from just incorporating?

When you first incorporate instead of staying a sole proprietor, you create one corporation that both operates the business and holds whatever it accumulates. A holdco structure splits those two functions across two corporations. You are not replacing your operating company — you are adding a parent above it. So a holdco is a step you take after incorporating, not an alternative to it, and only when there is a reason to separate the operating risk from the accumulated value.

The main reasons people use a holding company

In my practice, the case for a holdco almost always comes down to some combination of five things: protecting assets from creditors, moving profits up tax-efficiently, estate and succession planning, holding more than one business, and preserving a tax exemption on a future sale. Here is what each one really means.

1. Creditor and asset protection

This is the reason I hear most often, and it is a good one. Every operating business carries risk: a supplier dispute, a lawsuit, a lease gone wrong, a customer who sues. If all of your surplus cash and valuable assets are sitting inside the operating company, they are exposed to whatever the business's creditors might come after.

A holdco lets you do something about that. The operating company can pay its surplus cash and certain assets up to the holdco as dividends, moving them out of the company that carries the risk and beyond the reach of the operating company's creditors. Because the holdco is a separate legal entity, its assets are generally not available to satisfy opco's debts. If opco gets sued and goes under, the value you swept upstairs is, in the normal case, out of reach. That is the core of the protection, and it is real.

2. Moving profits up tax-efficiently

The mechanism that makes the protection above work is also where the tax efficiency lives, so the two go hand in hand. Dividends generally flow tax-free between connected Canadian corporations — this is what is meant by an intercorporate dividend. In plain terms, opco can move profits up to holdco without triggering immediate personal tax on the way, where they can be reinvested or protected. Earning income inside a corporation rather than personally can also defer tax.

I am going to be disciplined here, because this is exactly the kind of thing people get wrong when they read about it online: I am not going to quote rates or do tax math. Whether moving profits up to a holdco actually helps you, and by how much, depends entirely on your situation and has to be modelled by an accountant. The legal structure I can build; the tax case for it is your accountant's call. What I can tell you is that the tax-free intercorporate dividend is the plumbing that makes the whole holdco idea practical.

3. Estate planning and succession

Keeping valuable assets in a holdco can insulate family wealth from the operating business's risks — the same separation that protects against creditors also protects against the business dragging family assets down with it. It also supports succession planning. A common example is an estate freeze, where the current owner's interest is fixed at today's value and future growth accrues to the next generation, which can ease the transition of a family business.

I am describing these generally on purpose. Estate freezes and succession plans are built jointly by a lawyer and an accountant (and sometimes a financial planner) around your specific family and numbers — there is no template. If passing the business on, or protecting family wealth from it, is on your mind, a holdco is often part of the answer, but the design is bespoke. It connects closely to broader business exit planning in Ontario, which is worth reading alongside this.

4. Holding more than one business

If you run, or plan to run, more than one venture, a holdco is often the structure that ties them together. A single holding company can own the shares of several operating companies — frequently one corporation per business or property. Each operating company sits in its own corporation, so the risk of one is isolated from the others, and each can sweep its surplus up to the shared holdco at the top.

I see this constantly with people who own a couple of distinct businesses, or an operating company plus a piece of real estate. Rather than letting one risky venture's creditors reach the value of the other, you put each in its own box and let a common parent own them all. If a second venture is anywhere on your horizon, it is worth setting up the structure with that in mind so you are not rebuilding later.

5. Preserving the Lifetime Capital Gains Exemption on a sale

When you eventually sell, the Lifetime Capital Gains Exemption (LCGE) can shelter a large chunk of the gain on the sale of qualifying small business corporation shares — somewhere around $1.25 million, indexed, though you should confirm the current figure with your accountant. To qualify, the shares have to meet certain conditions, and one of them is roughly that the company be "pure" enough — not carrying too much in the way of passive investments and surplus cash.

Here is where a holdco helps: by sweeping surplus cash and investments up to the holding company, you can help keep the operating company "clean" so its shares stay eligible for the exemption on a future sale. The structure that protects you from creditors during the business's life can also protect a valuable tax exemption at the end of it. As always, whether your shares actually qualify, and how to keep them qualifying, is a question for your accountant — but it is one of the most compelling long-term reasons to consider the structure early. If a sale is the goal, my guide on asset purchase vs. share purchase in Ontario explains why share sales, where the LCGE lives, are often what a seller wants.

When a holdco is — and isn't — worth it

Here is the part people skip past in their excitement, and it is the part I care about most. Almost everything above is a genuine benefit, but every one of them assumes you have something to protect or plan around. If you do not, a holding company is just a second corporation costing you money for nothing.

In my experience a holdco starts to make sense once you have one or more of these:

• Meaningful surplus cash or retained earnings sitting in the operating company that you would rather protect than leave exposed.
• Valuable assets — investments, equipment, real estate, or accumulated cash — worth moving out of the risk-bearing business.
• More than one venture, where isolating each business in its own corporation under a common parent makes sense.
• Estate-planning or succession goals, such as passing a business to the next generation or insulating family wealth from business risk.

Is a holdco worth it for a single small business?

Usually not. If you have one small operating company with little surplus, the holdco gives you nothing to hold while still costing you a second set of filings and accounting every year. The benefit only appears once there is real value to move upstairs or a second venture to isolate — until then, the structure is overhead without a payoff.

And here is when it is usually not worth it: a brand-new, break-even, or single small operating business. If there is no surplus to sweep upstairs, no second venture, and no estate plan to serve, the holdco gives you nothing to hold while still costing you a second set of filings and accounting every year. I regularly talk people out of a holdco for exactly this reason — they read about the benefits without noticing that none of them apply to a company that is barely turning a profit yet. The structure can always be added later, once there is a reason for it.

The catch: cost, complexity, and genuine separateness

A holding company is not free, and it is not "set and forget." Before you decide, you have to weigh three real costs against the benefits — and understand the one that, if ignored, quietly destroys the protection you set it up for.

Cost and complexity. You are now running two corporations instead of one. That means a second set of annual returns, a second minute book to keep current, and more accounting and tax-filing work every single year. None of it is enormous, but it is ongoing, and it is the price of admission. If the benefits do not clearly outweigh that recurring overhead, the holdco is not earning its keep.

Genuine corporate separateness — or you lose the protection. This is the catch that matters most, and the one I see people get wrong. The creditor protection only holds because the holdco is a separate legal entity from opco — and a court will only respect that separateness if you actually maintain it. That means separate bank accounts and records for each company, and properly documented intercorporate transactions — the dividends and any loans or transfers between them recorded and resolved on, not just moved around informally.

If you run the two companies as one blurred entity — mixing the bank accounts, ignoring the paperwork, treating holdco's money as opco's piggy bank — a court can disregard the separation entirely. Lawyers call this piercing the corporate veil: when a structure is a sham or is run sloppily, a judge can look through it and treat the assets as available to the operating company's creditors after all. The whole point of the holdco evaporates. Keeping the two companies genuinely separate is not optional housekeeping — it is the thing that makes the structure work. This is part of why ongoing corporate maintenance and minute book work matters so much once you have more than one company.

Does a holdco affect my director duties?

You will likely be a director of both companies, and the duties travel with the role — you owe each corporation the duty to act honestly and in its best interests, and certain personal liabilities (unremitted source deductions and HST, unpaid wages) can reach a director of either company. Having two corporations does not dilute those obligations; it doubles the seats you sit in. I cover the exposure in detail in my guide to director duties and personal liability in Ontario.

How it's set up: with your accountant and a lawyer

I want to be direct about this, because it is where holdco structures most often go wrong: this is not a do-it-yourself decision, and it is not a self-serve online form. A holding company is set up with two advisors working together, and skipping either one is a mistake.

Your accountant drives the tax structure. They are the ones who model whether a holdco actually helps your numbers, how the dividends should flow, how it fits your overall tax and estate plan, and whether the LCGE is in play. Because everything in this article that touches tax depends on your specific situation, the accountant's analysis comes first — there is no point building a structure that does not pencil out.

The lawyer incorporates and structures it. I incorporate the holding company, structure the share ownership so holdco properly owns opco, and document the intercorporate relationship so the separateness that protects you actually holds up if it is ever tested. Getting the share structure right at this stage matters — it is the same lesson as on any incorporation, which is why I always tell people to think about it before they file, as I explain in what happens after you incorporate in Ontario. If you are at the point of building a group of companies, an incorporation lawyer and a business lawyer can put the whole structure together properly in step with your accountant.

Common mistakes I see

A few errors come up again and again with holding companies, and each one undercuts the reason for having one in the first place.

Setting one up too early. The most common mistake is building a holdco for a business that has nothing to put in it yet. You pay to incorporate and then pay every year to maintain a corporation that is holding nothing. Wait until there is a real reason.

Blurring the two companies. The second most common — and most dangerous — mistake is treating the holdco and opco as one. Mixed bank accounts, undocumented transfers, no resolutions for the dividends. This is exactly what lets a court pierce the veil and undo the protection. The separateness has to be genuine and documented.

Setting it up and then neglecting it. A holdco needs the same ongoing maintenance as any corporation — annual returns, an up-to-date minute book, proper records. A structure that is built and then ignored can give you all of the cost and none of the benefit, because the neglect itself is what a creditor's lawyer will point to.

Skipping one of the two advisors. Doing it with only an accountant means the legal structure and documentation may be weak; doing it with only a lawyer means the tax case was never properly modelled. Both is the answer.

Key takeaways

• A holdco holds; opco operates. A holding company is an ordinary corporation that owns the shares of your operating company and the value above it, instead of running the business itself.
• The big benefits are real but conditional. Creditor protection, tax-efficient movement of profits via tax-free intercorporate dividends, estate planning, holding multiple businesses, and preserving the Lifetime Capital Gains Exemption on a sale — all genuine, none automatic.
• It is usually not worth it early. A brand-new, break-even, or single small business has nothing to put upstairs; the holdco just adds cost. It earns its keep once there is surplus cash, valuable assets, more than one venture, or an estate plan.
• Separateness is the whole game. The protection only holds if you genuinely maintain two companies — separate accounts, clean records, documented transactions — or a court can pierce the veil and undo it.
• Set it up with an accountant and a lawyer. The accountant models the tax; the lawyer incorporates and structures it. This is not a do-it-yourself decision.

Frequently asked questions

What is a holding company?

A holding company — a "holdco" — is a corporation that holds the shares of your operating company and often the valuable assets above it, instead of running the day-to-day business itself. The operating company ("opco") earns the revenue, takes on the customer contracts, and carries the commercial risk. The holdco sits on top, owning opco's shares and parking surplus cash, investments, or property that you want kept separate from the business. It is a structure, not a special kind of company — a holdco is just an ordinary corporation used to hold rather than operate.

Do I need a holding company in Ontario?

Usually not at the start. For a brand-new, break-even, or single small operating business, a holdco adds setup cost, annual filings, and accounting for very little benefit. A holding company starts to make sense once you have meaningful surplus cash or retained earnings to protect, valuable assets, more than one venture, or estate-planning goals. The honest answer is that it depends on your numbers and plans, which is why this is a decision to make with an accountant and a lawyer rather than a default you reach for the moment you incorporate.

How does a holdco protect my assets from creditors?

The operating company can pay its surplus cash and certain assets up to the holdco as dividends, moving them out of the business that carries the commercial risk. Because the holdco is a separate legal entity, its assets are generally not available to satisfy the operating company's debts. The protection is real but conditional: it only holds if the structure is genuinely maintained — separate bank accounts and records, properly documented intercorporate transactions. A sham or sloppily run holdco can be set aside by a court, which is the concept of piercing the corporate veil. Separateness on paper is not enough.

What are intercorporate dividends?

An intercorporate dividend is a dividend paid from one corporation to another. In Canada, dividends generally flow tax-free between connected Canadian corporations — so an operating company can move profits up to its holding company without triggering immediate personal tax on the way. This is the mechanism that lets you sweep surplus cash out of the risk-bearing operating business and into the holdco, where it can be reinvested or protected. The exact treatment depends on the situation and how the corporations are connected, so the structure has to be modelled by an accountant rather than assumed.

Does a holding company save tax?

It can help with tax efficiency and deferral, but it is not an automatic tax saver, and I keep the specifics general because this is an accountant's domain. Two ideas come up most: dividends generally flow tax-free between connected Canadian corporations, so profits can move up to the holdco and be reinvested or protected without immediate personal tax; and earning income in a corporation rather than personally can defer tax. Whether either actually helps you, and by how much, depends entirely on your numbers. The exact benefit must be modelled by an accountant before you rely on it.

How does a holdco help with estate planning or selling?

Two ways come up most often. For estate planning, keeping valuable assets in a holdco can insulate family wealth from the operating business's risks and supports succession planning — for example, an estate freeze that locks in today's value for the next generation. For a future sale, a holdco structure can help keep the operating company "pure" so its shares stay eligible for the Lifetime Capital Gains Exemption on qualifying small business corporation shares. Both are general descriptions; the actual planning has to be built with an accountant and a lawyer around your specific situation.

When is a holding company worth the cost?

In my experience a holdco earns its keep once there is something real to protect or plan around — meaningful surplus cash or retained earnings, valuable assets, more than one business or property, or genuine estate-planning and succession goals. It is usually not worth it for a brand-new, break-even, or single small operating business that has nothing to sweep upstairs yet. The extra corporation means extra setup cost, annual filings, and accounting every year, so the benefit has to be worth that ongoing overhead. If there is little surplus and one simple business, wait.

What are the downsides of a holding company?

The main downsides are cost and complexity. You are running two corporations instead of one, which means a second set of annual returns, a second minute book to maintain, and more accounting and tax-filing work each year. There is also a discipline cost: the creditor protection only holds if you keep the two companies genuinely separate — separate bank accounts, clean records, properly documented transactions between them. If you run them as one blurred entity, a court can disregard the separation. A holdco set up and then neglected can give you the cost without the benefit.

Can a holding company own more than one business?

Yes, and that is one of the most common reasons to use one. A single holdco can hold the shares of several operating companies — one per venture is a frequent pattern — so that each business sits in its own corporation while a common parent owns them all. This lets you isolate the risk of each operating company from the others, sweep surplus from each up to the shared holdco, and manage the group as a whole. If you run, or plan to run, more than one venture, a holding company is often the structure that ties them together cleanly.

Do I set this up with a lawyer or an accountant?

Both — and that is not a hedge. Your accountant drives the tax structure: they model whether a holdco actually helps your numbers, how the dividends should flow, and how it fits your overall tax and estate plan. The lawyer incorporates the holding company, structures the share ownership, and documents the intercorporate relationship so the separateness that protects you actually holds up. This is not a do-it-yourself decision and not a self-serve online form. The two advisors work together, and skipping either one is where holdco structures most often go wrong.

Final thoughts

The honest answer to "do I need a holding company?" is the one nobody selling you a structure wants to give: it depends, and often the answer is "not yet." A holdco is a genuinely powerful tool for protecting surplus value from your business's creditors, moving profits up tax-efficiently, planning your estate and succession, holding more than one venture, and keeping a future sale eligible for a valuable tax exemption. But every one of those benefits assumes you have something worth protecting, and all of them depend on running the structure properly once it exists.

So the right question is not "can a holdco do useful things" — it obviously can. It is "do I have enough surplus, assets, ventures, or planning goals to justify a second corporation, and am I prepared to keep it genuinely separate." If yes, it can be one of the smartest structural moves you make. If not yet, the best advice is to wait and add it when there is a reason — the path stays open.

Because this is tax-adjacent, model it with your accountant first, then build it with a lawyer. If you want to talk through whether a holding company makes sense for your situation, call 416-554-1639 or book a free consultation. A short conversation, alongside your accountant, can usually tell you whether a holdco is worth it — or whether you are better off waiting.
