A holding company sits at the top of a corporate structure, owning shares in one or more operating businesses rather than running operations itself. For Canadian business owners, it’s one of the most useful — and most misunderstood — tools in tax and wealth planning.
This guide explains how holding companies actually function day-to-day: how they generate income, how money moves between the holdco and its operating company, how the structure is taxed under Canadian rules, and where the strategy works (and where it doesn’t).
If you’re still deciding whether to set one up, our companion article on how to start a holding company in Canada covers the incorporation process. This article focuses on what happens once the structure is in place.
Key Takeaways
- Holding companies don’t usually run operations — they own shares in operating companies (opcos) and earn income through dividends, interest, management fees, capital gains, and investment returns.
- In Canada, dividends moving from a connected opco to a holdco are typically tax-free under Section 112 of the Income Tax Act.
- Passive investment income inside a holdco is taxed at a high corporate rate (~50% in Ontario), with a refundable portion recovered when dividends are paid out.
- Holdcos provide creditor protection, tax deferral, succession-planning flexibility, and access to the Lifetime Capital Gains Exemption when the opco is eventually sold — but the LCGE is claimed by the individual shareholder, not the holdco.
- Anti-avoidance rules (Section 55(2), Section 84.1, passive income thresholds, TOSI) shape how the structure should be used.
What a Holding Company Actually Does?
Despite the size of names like Berkshire Hathaway, Brookfield Corporation, or Power Corporation of Canada, most Canadian holdcos are far simpler: a single corporation owned by an individual (or family) that owns the shares of one or more active businesses.
The holdco’s job is to:
- Hold shares of operating companies, real estate corporations, or marketable securities
- Receive dividends from those subsidiaries
- Invest excess cash in passive assets
- Provide centralized management to subsidiaries (sometimes)
- Protect retained earnings from operating risk
It’s not where the action happens — it’s where the wealth is parked while the operating business does its thing.
How a Holding Company Generates Income?
A Canadian holdco typically earns income from four sources. Each is taxed differently.
1. Inter-Corporate Dividends from the Opco
This is the most common — and most powerful — source of holdco income. When an operating company has retained earnings beyond what’s needed for operations, it can pay them up to the holdco as a dividend.
Between connected Canadian corporations (where the holdco owns more than 10% of votes and value of the opco), these dividends are generally deductible under Section 112 of the Income Tax Act — meaning the holdco receives them tax-free.
This is the mechanism that drives most Canadian holdco structures: excess cash flows up to the holdco, where it’s protected from operating risk and can be invested or eventually paid out to the individual shareholder when needed.
A caution: Section 55(2) can recharacterize certain inter-corporate dividends as taxable capital gains in specific circumstances (typically when dividends are paid in contemplation of a sale). This is technical territory that needs an accountant’s involvement.
2. Investment Income
Once cash is sitting in the holdco, it can be invested in:
- Marketable securities (stocks, ETFs, bonds)
- Guaranteed Investment Certificates (GICs)
- Real estate
- Private equity or venture investments
- Shares of other operating businesses
Investment income earned inside a CCPC is passive income for tax purposes, and it’s taxed at a high corporate rate — roughly 50% combined federal + Ontario — but a portion goes into the Refundable Dividend Tax on Hand (RDTOH) account and is refunded when the holdco pays a taxable dividend to its shareholders. The system is designed to achieve integration — meaning the total tax paid through the corporation should roughly equal the tax that would be paid if the income were earned personally.
Importantly, since 2019, if associated corporations earn more than $50,000 of passive investment income in a year, the operating company’s access to the Small Business Deduction (SBD) starts to grind down, eliminated entirely at $150,000 of passive income. This makes investment income strategy a key planning consideration, not just a yield question.
3. Management Fees and Interest
Some holdcos charge their operating subsidiaries:
- Management fees for centralized administration, executive services, or strategic oversight
- Interest on loans the holdco makes to the opco
These create active income at the holdco level (taxed at corporate rates) and a deduction at the opco level. They must be reasonable and supported by an actual services agreement — the CRA has historically challenged management fees that look like profit-stripping rather than genuine compensation for services. Documentation matters.
4. Capital Gains on Sale of Subsidiary Shares
If the holdco eventually sells the shares of an operating company at a profit, that gain is a capital gain inside the holdco. 50% is included in taxable income, taxed at the corporate passive-income rate, with the non-taxable half flowing into the Capital Dividend Account (CDA) — which can then be paid out to shareholders as a tax-free capital dividend.
A common point of confusion: the Lifetime Capital Gains Exemption (LCGE) is not available to the holdco on this sale. The LCGE is available only to individual shareholders selling Qualified Small Business Corporation (QSBC) shares directly. If the opco is held by a holdco, structuring around this — sometimes through a pre-sale reorganization — is critical to access the LCGE.
Structure: Holdco-Opco in Practice
The classic Canadian setup looks like this:
Individual Shareholder → Holdco → Opco (active business)
The individual owns all the shares of the holdco. The holdco owns all (or a controlling block) of the shares of the opco. Profits earned by the opco are taxed first at the corporate level (with access to the SBD on the first $500,000 of active business income, where applicable), then moved up to the holdco tax-free as dividends.
More sophisticated structures may include:
- A second holdco for additional creditor or succession layering
- A family trust between the individual and the holdco, allowing multiple family members to be discretionary beneficiaries (subject to TOSI rules)
- A “realtyco” — a separate corporation holding business real estate, often leased back to the opco
- Multiple opcos owned by one holdco, each compartmentalizing different lines of business
Types of Holding Companies (in Canadian Practice)
While the original concept of “holding company” is global, in Canadian practice the most useful distinctions are:
Pure holding company. Owns only investments — shares of subsidiaries, securities, real estate. No active business operations of its own. Most personal/family holdcos fall into this category.
Mixed-purpose holdco. Holds investments and provides management or other services to subsidiaries. Earns both passive and active income.
Investment holdco (Investco). A holdco whose only role is to hold a portfolio of marketable securities, often a “purification vehicle” used to strip passive assets out of an opco so the opco continues to meet QSBC tests for the LCGE.
Realtyco. A corporation specifically holding business real estate, kept separate from the opco so the property is protected from operating liabilities and rent expense is preserved as a deduction.
Trustee/parent holdco. Used in family-trust planning, often holding shares as a corporate beneficiary or as the trust’s general partner.
Advantages of a Holdco Structure
Creditor protection. Excess cash sitting in an active opco is exposed to lawsuits, contract disputes, and supplier claims. Moving retained earnings to a holdco puts a corporate wall between business risk and accumulated wealth.
Tax deferral. Rather than paying out all profits to yourself personally (and being taxed at top marginal personal rates), you can leave funds in the holdco and invest. Personal tax is paid only when funds are eventually distributed.
LCGE access. With proper structuring — especially purification of the opco — the individual shareholder can claim the $1.25 million (2026) Lifetime Capital Gains Exemption on a future sale of the opco’s shares.
Estate planning. Holdcos are central to estate freezes, succession transitions, and family-trust structures that allow business value to pass to the next generation tax-efficiently.
Centralized management. A single holdco can oversee multiple opcos, simplifying governance, banking, and consolidated reporting.
Income splitting (limited). Subject to Tax on Split Income (TOSI) rules, dividends paid through a holdco can, in some cases, be allocated among family members.
Disadvantages and Compliance Costs
A holdco is not free. You take on:
- Annual corporate tax filings (T2 return) for the holdco
- Bookkeeping and financial statements for an extra entity
- Legal and accounting fees for both the holdco and the opco
- The new beneficial ownership register (ISC filings)
- More complex inter-company tracking — loans, dividends, management fees
For a small operating business with little excess cash, the cost of running a holdco often outweighs the benefit. The sweet spot is typically when the opco starts generating retained earnings beyond what’s needed for operations — generally $50,000+ in annual surplus.
Canadian Examples
You don’t need to be Berkshire Hathaway-sized for a holdco to make sense. Some recognizable Canadian holding companies:
- Power Corporation of Canada — the Desmarais family’s holding company controlling Great-West Lifeco and IGM Financial
- Brookfield Corporation — a global asset manager structured as a holding company
- George Weston Limited — holds Loblaw, Choice Properties REIT, and other interests
- Onex Corporation — private equity holdco
- Saputo Holdings — controlling vehicle for Saputo Inc.
For ordinary Canadian business owners, a holdco is typically a single-shareholder Ontario or federal corporation sitting above a single trades, professional, or retail opco — modest in scale, but using the same fundamental mechanics.
Final Thoughts
A holding company is a tool. It does some things extremely well — protecting retained earnings, deferring personal tax, enabling succession planning, and providing a vehicle for inter-corporate dividends — and it does other things poorly or not at all (such as claiming the LCGE on its own behalf).
For Canadian business owners with a profitable, established operating company, a properly structured holdco can save tens or hundreds of thousands of dollars over the life of the business. Done wrong — or done too early — it just adds compliance cost without delivering the benefits.

Frequently Asked Questions
How does a holding company make money?
Primarily through dividends from its operating subsidiaries (tax-free under Section 112 between connected Canadian corporations), investment income on retained funds, management fees and interest charged to subsidiaries, and capital gains on the sale of subsidiary shares.
Is a holding company taxed differently in Canada?
Yes. Inter-corporate dividends from connected Canadian corporations are generally received tax-free. Passive investment income inside the holdco is taxed at a high rate (~50% in Ontario), with a refundable component returned through RDTOH when dividends are paid out. Active income earned by the holdco (e.g., management fees) is taxed like any other corporate active income.
Can a holding company claim the Lifetime Capital Gains Exemption?
No. The LCGE is available only to individual shareholders selling Qualified Small Business Corporation shares directly. If your opco is held by a holdco, accessing the LCGE typically requires a pre-sale reorganization to put the qualifying shares back into individual hands.
Are holding companies a good investment?
For business owners with excess retained earnings in their opco, yes — the creditor protection, tax deferral, and succession flexibility often justify the compliance cost. For shareholders of public holding companies (like Brookfield or Power Corp), they offer diversified exposure but carry the usual market and concentration risks; that’s a different question entirely.
What are the disadvantages of a holding company?
Higher ongoing compliance costs (extra corporate tax return, bookkeeping, statements), the complexity of inter-company transactions, exposure to anti-avoidance rules like Section 55(2) and TOSI, and the loss of direct LCGE access on the operating shares.
Do I need a lawyer and an accountant to set up a holding company?
Yes — both. A lawyer drafts the incorporation documents, share structure, and any shareholders’ agreements. An accountant designs the tax structure, advises on share classes, and handles ongoing compliance. Doing this without professional help is one of the most common ways business owners create expensive problems later.
