May 22, 2025


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).

Key Takeaways

  • Applies to non-primary residence sales.
  • 50% of gain is taxable as income.
  • Principal residence exemption may apply.
  • Planning helps reduce tax impact.
  • Professional advice recommended.

Canada Is Building More Homes (But Fewer Of Them Are For People To Own)

Canada Is Building More Homes (But Fewer Of Them Are For People To Own)

It’s no secret that developers have lost faith in Canada’s once-booming condo sector. It’s also no secret that the rental segment has emerged as something of a saving grace for the housing market, with new and pivoted projects alike benefiting from government-backed incentives. But a new report from Desjardins underscores that the broad volley from condo to rental is not a risk-free trade-off.

Authored by Economist Kari Norman, the report points out while there have been around 130,000 rental housing starts recorded over the last four quarters, condo starts have slipped below the 50,000-mark for the first time since the 2009 global recession.
