Gains and Losses

Capital-gain and capital-loss terms for cost base tracking, dispositions, and taxable inclusion.

Capital-gain reporting starts with careful records, a sale or deemed disposition, and the correct cost base.

What Belongs Here

Use this subsection when the question is about the tax result of selling or disposing of property, not when the issue is ordinary interest or dividend reporting.

Best Starting Pages

Use these pages together when the question is not “what investment income slip is this?” but “what happened when an asset was sold?”

Practical Reader Path

Readers usually need all three pages in sequence:

  1. identify whether a disposition created a capital gain
  2. calculate or check the Adjusted Cost Base
  3. understand how much of the result becomes a Taxable Capital Gain

In this section

  • Adjusted Cost Base
    Adjusted cost base is the running tax cost of capital property used to calculate a capital gain or loss.
  • Capital Gain
    A capital gain arises when capital property is disposed of for more than its adjusted cost base and selling costs.
  • Taxable Capital Gain
    The taxable capital gain is the included portion of a capital gain that flows into income under current Canadian rules.
