Ontario is Canada's most populous province and a major origin point for Canadians moving abroad — to the United States, the UK, Australia, Europe, and the UAE. The tax implications of leaving Ontario and Canada require careful planning: the CRA's deemed disposition rules can trigger significant capital gains on investment portfolios and business interests even before you've sold anything. The departure year T1 is typically the most complex Canadian return you will file, combining partial-year provincial income with departure-day capital gains calculations. This guide covers the key steps for Ontarians leaving Canada permanently or for an extended period.
Moving from Ontario to another Canadian province is different from moving internationally:
Interprovincial move (within Canada): No deemed disposition. No departure return. Provincial income tax shifts to your new province as of December 31 — pay the new province's tax for the full year if you are resident there on December 31. No change to RRSP, TFSA, or RESP treatment. No non-resident withholding on investments. OHIP ends; new province's health coverage begins (there may be a 3-month waiting period in some provinces, though interprovincial transfers are often faster).
International departure: Full deemed disposition on worldwide assets on departure date. Departure return required. Non-resident withholding applies to future Canadian income. RRSP withdrawals subject to withholding. TFSA accumulation stops. Canadian rental income requires CRA non-resident rental filing (Section 216). This guide focuses on international departure — moving from Ontario to another country permanently or for a significant period.

Ontario taxes capital gains at your marginal rate on the inclusion amount (50% of the gain included in income). If you are planning to leave Ontario soon, you face a timing decision: sell before departure (pay Ontario capital gains now, avoid deemed disposition on those assets) or sell after departure as a non-resident (25% Canadian non-resident withholding on capital gains from taxable Canadian property; potentially less tax on non-Canadian assets depending on your new country). For most investment portfolios: a deemed disposition before departure creates the same tax event as actually selling — the timing choice matters only for liquidity and destination-country tax consequences.
Employer Health Tax (EHT) is paid by Ontario employers on payroll — it is an employer obligation, not an employee tax. As an employee leaving Ontario, your employer is responsible for EHT on your Ontario earnings through your last day of work in Ontario. EHT is automatically handled by Ontario payroll — you do not file or pay it personally. If you are self-employed in Ontario (subject to EHT as an employer): notify the Ontario Ministry of Finance of your cessation of Ontario business activity. EHT final return required for the year of departure (covering January 1 to departure date). There are no personal EHT obligations after you cease Ontario employment or business activity.
Non-resident landlords with Canadian rental property must comply with CRA Section 216 non-resident rental rules. Your tenant (or property manager) is technically required to withhold 25% of gross rent and remit to CRA. In practice, you should register as a non-resident landlord with CRA and file a Section 216 return (T1159) annually — reporting gross rents and net rental income. Under the Section 216 election, you pay tax on net rental income (after expenses) at graduated Canadian rates, which is almost always better than the 25% gross withholding. Ontario property tax and land transfer tax: continue to apply as property owner regardless of non-residency. When you eventually sell the Toronto property: file a Section 116 certificate with CRA; purchaser withholds 25% of sale price as security; you file a CRA non-resident disposal return and receive a refund of the difference between withholding and actual capital gains tax.
