Capital Gains Tax in Canada

12 min readUpdated December 2024

50% Inclusion Rate

In Canada, only 50% of capital gains are taxable for most individuals. This makes capital gains one of the most tax-efficient forms of investment income.

What Is a Capital Gain?

A capital gain occurs when you sell capital property for more than you paid for it:

  • Stocks and shares
  • Real estate (except principal residence)
  • Bonds and mutual funds
  • Cryptocurrency
  • Art, collectibles, jewelry
  • Business assets

How Capital Gains Are Taxed

The Inclusion Rate

  • 50% inclusion: Only half of your gain is taxable
  • Added to your other income
  • Taxed at your marginal rate

Example Calculation

  • Buy shares for $10,000
  • Sell for $15,000
  • Capital gain: $5,000
  • Taxable capital gain: $2,500 (50%)
  • If marginal rate is 40%: Tax = $1,000

Effective Rate: With 50% inclusion, if your marginal rate is 40%, your effective capital gains rate is only 20% (40% × 50%).

Adjusted Cost Base (ACB)

The ACB is your cost for tax purposes:

What's Included in ACB

  • Purchase price
  • Commissions and fees (buying and selling)
  • Legal fees
  • Transfer taxes

ACB for Multiple Purchases

When you buy the same security at different prices:

  • Calculate weighted average cost
  • Total cost ÷ Total shares = ACB per share
  • Must track separately for each security

Example

  • Buy 100 shares at $10 = $1,000
  • Buy 100 shares at $15 = $1,500
  • Total: 200 shares, $2,500 cost
  • ACB per share: $12.50

Capital Losses

Using Capital Losses

  • Offset capital gains in the same year
  • Carry back 3 years
  • Carry forward indefinitely
  • Only 50% of loss is deductible (matches inclusion)

Superficial Loss Rule

Loss denied if:

  • Buy same or identical property
  • Within 30 days before or after sale
  • You or affiliated person acquires it
  • Loss added to ACB of new shares

Warning: The superficial loss rule prevents "wash sales"—selling to trigger a loss and immediately rebuying. Wait 31+ days or buy a similar (but not identical) investment.

Capital Gains Exemptions

Principal Residence Exemption

  • Gains on your home are tax-free
  • One principal residence per family per year

  • Partial exemption if not always principal residence
