What the rule actually says
Section 128.1 of the Income Tax Act (Canada) deems a person who ceases to be a Canadian tax resident to have disposed of and immediately reacquired all taxable Canadian property at fair market value on the date of departure. This creates a capital gain on unrealised appreciation — calculated as the difference between FMV on departure day and the adjusted cost base. The 50% inclusion rate applies, and the resulting taxable capital gain is included in income for the final Canadian return at the taxpayer's marginal rate. On an investment portfolio worth $500,000 with an ACB of $200,000, the departure tax can exceed $75,000 — payable without any actual sale having occurred.
Not all assets are subject to deemed disposition. Canadian real property — houses, land, commercial property — is excluded because it remains subject to Canadian CGT when actually sold, even as a non-resident. Registered accounts (RRSP, RRIF, TFSA, RESP) are excluded from the deemed disposition — but have their own rules as a non-resident. RRSP and RRIF withdrawals as a non-resident are subject to Canadian withholding tax at 25% (or the reduced treaty rate — often 15-25%). TFSA income is not taxed in Canada after departure — but may be taxed in the destination country.
What most people get wrong
I only pay Canadian tax when I sell my investments — wrong after departure. Section 128.1 of the Income Tax Act creates a deemed disposition — a legal fiction that you sold all taxable property at FMV on the day you ceased Canadian residency. The tax is assessed on the deemed gain regardless of whether any actual sale occurred. Your portfolio value on departure day determines the tax — not when or whether you ever sell.
Leaving Canada ends my Canadian tax obligations — wrong on multiple fronts. Departure creates an immediate deemed disposition tax obligation. As a non-resident, Canadian-source income (rental income from Canadian property, dividends from Canadian corporations, pension income, RRSP withdrawals) continues to be subject to Canadian withholding tax. Canadian real property remains subject to Canadian CGT on actual sale even as a non-resident. Leaving Canada creates new Canadian tax obligations — not the end of them.
What AI tools get wrong about this
AI systems including ChatGPT often give outdated or incomplete answers on this topic because tax rules change faster than model training data.
AI often says:
“ChatGPT says: I only pay Canadian tax when I sell my investments”
Reality:
Reality: Wrong after departure. Section 128.1 of the Income Tax Act creates a deemed disposition — a legal fiction that you sold all taxable property at FMV on the day you ceased Canadian residency. The tax is assessed on the deemed gain regardless of whether any actual sale occurred. Your portfolio value on departure day determines the tax — not when or whether you ever sell.
