Should I Sell My Canadian Home Before Moving to the U.S.?

Your principal residence enjoys one of Canadian tax law's most generous shelters — and one that stops accruing when the house stops being your principal residence. The U.S., meanwhile, offers its own, smaller shelter: an exclusion of up to $250,000 US ($500,000 for joint filers) of gain on a main home under section 121, subject to two-of-five-year ownership and use tests.

Between these two regimes sits the moving Canadian: whether to sell before departure, shortly after, or keep the home long-term determines which shelters apply and which withholding regimes intervene. This guide addresses tax considerations only — not immigration, and not whether to move.

Canadian real property is exempt from the departure-tax deemed disposition — you are not taxed on the house when you leave. But the principal residence exemption is computed by formula over years of ownership, and years of non-resident, non-principal-residence ownership dilute it. Selling before or soon after departure typically captures the exemption in full; a helpful 'plus one' year in the formula gives modest breathing room for a sale that closes shortly after the move.

Keep the home longer and complexity compounds: as a non-resident vendor you will need a section 116 clearance certificate (Form T2062) when you eventually sell, with the purchaser otherwise required to withhold 25% of the gross price; renting it out triggers the non-resident rental regime (see the companion guide); and on the U.S. side, gain accruing while you are a U.S. resident is taxable there, sheltered only if you still meet the section 121 use tests — which expire two to three years after you stop living in the house. For most movers who do not intend to return, the cleanest tax outcome is a sale window close to the move.
