A CRA tax exemption that eliminates capital gains tax on the profit from selling your primary home. To qualify, the property must be your principal residence for each year you are claiming the exemption, and only one property per family unit can be designated as a principal residence for any given tax year. You must report the sale on your tax return even though no tax is owed.
Why It Matters
The PRE is the single most valuable tax benefit available to Canadian homeowners. On a GTA home that has appreciated by $300,000, the exemption saves you tens of thousands in taxes. But you must report the sale to CRA -- failing to do so can trigger penalties. If you own multiple properties, strategic designation of your principal residence across different years can maximize the exemption.
Real-World Example
You bought a detached house in North York for $750,000 in 2018 and lived in it as your principal residence for seven years. You sell it in 2025 for $1,100,000, realizing a $350,000 gain. Because you designate it as your principal residence for all seven years of ownership, the entire $350,000 gain is tax-free under the PRE. If you had also owned a cottage during that period, you would need to choose which property to designate for each year to maximize the overall tax benefit across both properties.
Ontario & GTA Context
Ontario homeowners benefit from the PRE at the federal and provincial level, eliminating both federal and Ontario capital gains tax. The CRA requires you to report the sale on Schedule 3 of your tax return and complete Form T2091, even though no tax is owed. Failure to report can result in a penalty of $100 per month up to $8,000. The one-plus rule allows you to designate your home for one extra year, which is particularly useful when you own two properties briefly during a move.
How It Works in Practice
If you own multiple properties, work with a tax accountant to model the optimal designation strategy across all years of ownership. The property with the largest per-year gain should generally receive the designation for the most years. Keep records of your purchase price, sale price, and the dates you lived in each property.
