Off-market buyers in Ontario spend most of their time hunting for the right deal. Fewer spend time on the tax bill. That is a costly gap. How a flip is taxed can turn a strong spread into a thin one.
This guide covers how Ontario taxes a house flip in 2026. It is written for cash buyers and investors who buy below retail, fix, and resell. The goal is simple. Know the rules before you buy, not after you sell. For the wider picture on sourcing deals, start with our guide on how to buy off-market investment properties in Canada.
How Ontario Taxes a House Flip
Ontario does not have its own house flipping tax. British Columbia brought one in for 2025. Ontario did not follow. So an Ontario flip is taxed under the federal rules alone.
Two things can still apply. First, income tax on your profit. Second, HST on the sale in some cases. Most new investors plan for the first and forget the second. Both can take a real bite, and both are easier to handle when you price them in up front.
The profit on a flip is almost always taxed as business income. It is not treated as a capital gain. That one point drives most of the tax bill, so it is worth understanding in full.
The Federal 365-Day Flipping Rule
Since January 1, 2023, Canada has a residential property flipping rule. It still applies in 2026. If you sell a residential property you owned for less than 365 straight days, the profit is deemed business income. It is fully taxable. You cannot report it as a capital gain. You cannot use the principal residence exemption to shelter it.
The rule also reaches assignment sales. If you sell the right to buy a property, such as a pre-construction contract, the same clock applies.
There are exceptions for genuine life events. The automatic rule can be set aside when the sale was caused by one of these:
- Death of the owner or a related person
- A new person joining the household, such as a birth, an adoption, or a parent moving in
- A breakdown of a marriage or a common-law relationship
- A serious illness or disability
- A work relocation or an involuntary job loss
- A threat to personal safety
- Insolvency, or the property being destroyed or expropriated
One warning. Even when an exception applies, the Canada Revenue Agency can still treat the profit as business income under the normal tests. The exception only switches off the automatic rule. It is not a free pass.
Business Income vs Capital Gains
This is where the real money sits. A capital gain is only half taxable. Business income is fully taxable at your marginal rate.
Here is a simple example. Say you clear 100,000 dollars on a flip. As a capital gain, only 50,000 dollars is added to your income. As business income, the full 100,000 dollars is added. At a top Ontario marginal rate near 53.5 percent, that difference is large.
Some investors ask about the 2024 plan to raise the capital gains inclusion rate to two-thirds. The federal government cancelled that plan in March 2025. The inclusion rate stays at one-half for 2026. That is good news, but it only helps property that truly qualifies as capital. A flip rarely does.
The CRA decides business income versus capital by weighing your intent, how long you held, how often you do this, the work you put in, and why you sold. A buy, renovate, and sell pattern points straight at business income. Holding a bit longer does not automatically fix it.

HST and the Substantial Renovation Trap
The resale of a used home is normally free of HST. Many flippers assume that covers every deal. It does not.
If you substantially renovate a home, the CRA can treat you as a builder. A substantial renovation means roughly 90 percent or more of the interior was removed or replaced. When that happens, the sale is treated like new housing. You may have to charge and remit 13 percent HST in Ontario.
A cosmetic refresh is different. Fresh paint, new floors, and a kitchen update usually do not count as a substantial renovation. The gut jobs are the ones that trigger it. If your plan is a deep rebuild, price the HST in before you buy. Our guide to handyman specials and fixer uppers in Ontario covers how to tell a cosmetic project from a full rebuild.
Where the Margin Really Comes From
Taxes take a share of every flip. You cannot change that. What you can change is your buy price. The lower you buy, the more spread you keep after tax.
That is why off-market matters. A distressed property bought below retail gives you room that a retail listing does not. Buying right is the part of the deal you control.
This is what Jania Group does. We are a real estate investor and buyer, not an agent or a brokerage. We put wholesale and off-market deals in front of serious buyers. That includes fixer uppers, distressed properties, and value-add homes that fit a flip or a BRRRR.
Here is what our buyers tend to look for:
- Fixer uppers and handyman specials with real renovation upside
- Below-retail pricing that protects the margin after tax
- Distressed and motivated-seller situations
- Buy-and-hold deals with positive cash flow
You can see how we source these across the province on our Ontario off-market properties page, and in markets like Toronto, Hamilton, and Windsor.

If you flip in Ontario, your tax result is largely set the day you buy. Buy below retail and the numbers still work after the CRA takes its cut. Buy at retail and there is little room left.
