What is Capital Gains Tax?
Capital gains tax is a federal tax on the profit earned from the sale of a property or investment that has increased in value, applied when the asset is sold for more than its adjusted cost base.
Why Capital Gains Tax Matters in Real Estate
In Canadian real estate, capital gains tax applies to properties that are not the seller’s primary residence—such as rental properties, cottages, or investment real estate. When a property is sold, 50% of the gain is added to the seller’s taxable income.Key considerations include:
- The principal residence exemption excludes most owner-occupied homes
- Costs like legal fees and real estate commissions reduce the gain
- Tax implications should be factored into investment strategy
Formula: Capital Gain = Sale Price - (Purchase Price + Expenses + Capital Improvements)
Capital gains can significantly affect net proceeds from a sale, especially for long-held properties that have appreciated substantially. Sellers should consult with tax professionals and retain accurate records to properly calculate gains.Understanding how capital gains tax works helps investors make informed decisions, time their sales effectively, and plan for tax obligations at year-end.
Example of Capital Gains Tax
A seller buys a cottage for $250,000 and sells it for $450,000. After deducting $15,000 in improvements and $20,000 in selling costs, the taxable capital gain is $82,500 (50% of $165,000).

National average resale-price growth and housing-starts growth, smoothed over three months. The comparison illustrates the cycle; it does not establish how much a price change causes construction to change.
Trailing 12-month starts in centres of 50,000 or more remove the usual monthly seasonality. Ownership combines the homeowner and condominium categories; rental is shown separately.
Six-month averages of provincial starts, expressed at annual rates. The smoothing reduces the influence of individual apartment projects.
The same August benchmark compared with two different starting points. Three-month changes are not annualized.
Average sale prices show the difference in purchase costs across markets. They do not measure affordability relative to local incomes or construction costs.
Newfoundland and Labrador remains above its pre-pandemic sales pattern, but August activity was below last year. Historical lines retain their original release vintages.









Average and median describe different aspects of the same month’s transactions. Both are affected by the mix of homes sold.
Category averages compare different homes and locations; the gaps are not estimates of the cost to upgrade an otherwise identical property.
The five categories shown account for 5,000 of the board’s 5,057 sales. The remaining 57 transactions were in other housing categories.
Monthly observations are not seasonally adjusted. Active listings count properties available at month-end; they are not construction inventory.
Average and median prices share one dollar axis. These unadjusted transaction measures do not control for changes in the homes sold.
TRREB’s 416/905 categories compare the apartments sold in each area. The difference does not isolate a location premium for equivalent units.
