Why non-resident status changes the tax mechanics
Canada requires non-resident sellers of Canadian real property to notify the Canada Revenue Agency about the disposition and generally have a portion of the sale proceeds withheld at closing, pending confirmation of the actual tax owed — a mechanism resident sellers don't encounter in the same way. This isn't a penalty for being a non-resident; it's how the CRA secures the eventual tax obligation from someone who may not have an ongoing Canadian tax presence otherwise.
There's a process — a clearance certificate — that can reduce or release withheld funds once the actual tax liability is confirmed, but it takes real time and needs to be initiated properly, which is exactly why this needs specialist involvement well before closing, not arranged at the last minute.
How this interacts with the estate's own deemed disposition
Separately from a non-resident beneficiary's own tax situation, the estate itself generally already dealt with a deemed disposition at the date of death, which sets the beneficiary's cost base going forward. A non-resident beneficiary then faces their own withholding and reporting obligations if and when they sell the inherited property — two related but distinct tax events, both worth having a cross-border accountant walk through specifically.
Why timeline planning matters more here than in a typical sale
Because the clearance certificate process and withholding mechanics take real time to work through, a non-resident heir selling an inherited Canadian house should expect the closing and post-closing process to take longer than a standard domestic sale, and should start the tax-side conversation with a qualified accountant as early as possible — ideally before an offer is even accepted, not after.
