Canada includes 50% of the gain in taxable income, then applies your marginal rate. There is no annual CGT allowance like the UK £3,000; TFSA room is the tax-free wrapper.

Q: Which countries charge 0% CGT?

Singapore and Hong Kong do not levy capital gains tax on typical share sales. That is not a recommendation to relocate — residency and anti-avoidance rules still apply.
