Capital Gains Inclusion Rate in Canada: What It Means for Investors

When you sell an investment for a profit in Canada, you pay tax on a capital gain — but not on the entire gain. Canada’s 50% inclusion rate means only half your capital gain is added to your taxable income.

How the 50% Inclusion Rate Works

Example: You buy 100 shares at $20 each ($2,000) and sell for $70 each ($7,000).

Capital gain = $7,000 − $2,000 = $5,000
Taxable portion (50%) = $2,500
This $2,500 is added to your income and taxed at your marginal rate

If you’re in a combined federal + provincial marginal rate of 43%, your tax on this gain = $2,500 × 43% = $1,075 — an effective rate of 21.5% on the $5,000 gain.

What Qualifies as a Capital Gain?

Stocks, bonds, mutual funds, ETFs
Real estate (except your principal residence)
Cryptocurrency
Business assets
Foreign property

Not capital gains (different tax treatment):

Employment income
Business income
RRSP/RRIF withdrawals
Interest income

Adjusted Cost Base (ACB)

The capital gain is calculated as Sale Proceeds − ACB − Selling Costs. The ACB is what you originally paid plus any acquisition costs (commissions, legal fees). For stocks purchased multiple times, you use the average cost method.

Capital Losses

Capital losses can offset capital gains. Unused losses carry back 3 years or carry forward indefinitely. Only the taxable portion is offset (50% of losses against 50% of gains).

Principal Residence Exemption

If you sell your home that qualifies as your principal residence for every year you owned it, the entire gain is exempt from tax. You must report the sale on Schedule 3 of your T1 return.

Lifetime Capital Gains Exemption (LCGE)

The LCGE provides a once-in-a-lifetime shelter for gains on:

Qualified Small Business Corporation (QSBC) shares: Up to $1,250,000 exempt (2025)
Qualified Farm Property and Qualified Fishing Property: Up to $1,250,000

To qualify for the QSBC exemption, the shares must be in a Canadian-controlled private corporation (CCPC) that has been active and primarily carrying on business in Canada throughout the past 24 months.

Corporate Class Funds & ETFs

Some mutual fund structures allow investors to switch between funds without triggering capital gains — a tax-deferral strategy for non-registered accounts.

Planning Tips

Harvest losses before year-end to offset gains realized during the year

Donate appreciated securities to charity — the capital gain is exempt on donated publicly listed securities
