I don’t disagree about using taxes to deal with this (though noncompliance and loopholes are a problem), but to clarify, non-residents pay tax on the sale of Canadian real estate. This is written into all reciprocal tax treaties. The only way out of this would be if the house was a principal residence, which is the same rule as applies to residents selling their principal residence. Apologies for all the residence/residents.
