An operating company runs your active business, a holding company is a separate corporation used mainly to own shares or assets, and a family trust is a legal relationship where trustees hold property for beneficiaries. Most business owners start with just an operating company and add the others only when a specific goal, like investing surplus profit or planning a sale, calls for it.
Here is how the three compare, and where each fits.
Quick comparison
| Question | Operating company (OpCo) | Holding company (HoldCo) | Family trust |
|---|---|---|---|
| What is it? | Corporation carrying on the active business | Corporation used mainly to own shares or other assets | Legal relationship administered by trustees for beneficiaries |
| Main role | Earn revenue and bear operating risk | Hold surplus assets/shares and support corporate planning | Flexible ownership, succession, and allocation within trust and tax rules |
| Who controls it? | Directors and shareholders | Directors and shareholders | Trustees under the trust deed |
| Main benefit | Separate legal person; access to corporate tax rules | Potential personal-tax deferral and risk separation | Succession flexibility and possible allocation of eligible gains |
| Main limitation | Operating liabilities and compliance | Extra filings, passive-tax rules, LCGE ownership complications | Cost, reporting, TOSI/attribution, fiduciary duties, and the 21-year rule |
What is an operating company?
An operating company (OpCo) runs the day-to-day business: earning revenue, employing people, and carrying the operating risk. Incorporating creates a separate legal person, which can help protect a shareholder’s personal assets from the business’s debts and claims. That protection applies to shareholders in their capacity as shareholders; directors and officers can still face personal liability for certain obligations (for example payroll, tax, or statutory duties).
What is a holding company?
A holding company (HoldCo) is another corporation used mainly to own shares or assets, such as investments, real estate, or the operating company’s shares. It does not have to own the operating company in every structure. Owners often use a HoldCo to hold surplus profit and investments apart from the operating company’s risk.
Where the share structure allows, the operating company can declare a dividend to a corporate shareholder like the holding company. Such dividends between connected Canadian corporations are generally deductible to the recipient under section 112, but this is not unconditional. Part IV tax and other rules can apply, and it is best seen as personal-tax deferral rather than a permanent saving.

What is a family trust?
A family trust is a legal relationship in which trustees hold and administer property, often business shares, for beneficiaries. It is not a corporation. A trust can support succession and, in a structured sale, the allocation of eligible gains among family members, but it brings trustee duties, annual filings, and the 21-year rule.

Which structure do you need, and in what order?
There is no single structure that is right for everyone. A few decision triggers help:
- Start with the operating company. An incorporated active business runs through an operating company. (A corporation that only holds investments is a holding company, not an OpCo.)
- Consider a holding company once the operating company regularly earns more after-tax profit than you need personally and you want to hold or invest that surplus away from business risk.
- Consider a family trust when succession or a future share sale becomes a real goal.
Setting up entities before you actually need them can create years of unnecessary cost and, for a trust, early 21-year-rule planning. Rather than defaulting to “set it all up now,” match each layer to a real trigger.
Family trusts and the LCGE, briefly
When a trust owns qualifying shares and the business is sold in a properly structured arm’s-length sale, the trust or its trustees sell the shares and can allocate and designate eligible gains to individual beneficiaries, each of whom might use their own lifetime capital gains exemption (LCGE) of $1,275,000 in 2026. With several qualifying beneficiaries, that creates a larger theoretical maximum of eligible gains, but it is a ceiling, not a promised saving, and it depends on each beneficiary’s eligibility, the qualified small business corporation (QSBC) tests, the tax on split income (TOSI), and other rules. The QSBC tests look at the company’s assets (broadly, active-business use over the relevant period) and the ownership period, and they are more nuanced than one person simply holding shares for 24 months.
Frequently asked questions
What is the difference between an operating company and a holding company?
An operating company runs the active business: it earns revenue, employs people, and carries the operating risk. A holding company is a separate corporation used mainly to own shares or assets, such as investments or the operating company’s shares, without carrying on active operations. Many owners use a holding company to hold surplus profit apart from business risk.
What does a family trust add to an operating and holding company structure?
A family trust is a legal relationship where trustees hold property, often business shares, for beneficiaries. Added to a corporate structure, it can support succession planning and, in a carefully structured sale, allow eligible gains to be allocated among family members. It also brings trustee duties, extra reporting, and the 21-year deemed-disposition rule, so it suits specific goals rather than every owner.
Do I need a holding company if I already have an operating company?
Not necessarily. Many owners do well with a single operating company for years. A holding company usually becomes worth considering once the operating company earns more after-tax profit than you need personally and you want to hold or invest that surplus away from business risk. The decision depends on profit, risk, and future sale plans, not on company size alone.
Which structure best protects assets from creditors?
These are not interchangeable tools, so it is worth separating them. Holding surplus assets in a separate holding company may help isolate them from the operating company’s day-to-day creditors. A family trust raises different questions again, because it changes who owns the property rather than simply where it sits. Neither provides automatic protection. Personal guarantees, transfers made after a claim arises, liabilities attached directly to an asset, timing, and the applicable law all affect the outcome, so this needs legal review rather than a structural rule of thumb.
In what order should you set up these entities?
Start with the operating company, since every incorporated active business runs through one. Consider a holding company once the operating company builds surplus you want to protect or invest. A family trust is usually added when succession or a future share sale is a real goal. Setting up entities before you need them can create years of unnecessary cost.
