If you hold or want a Canadian mortgage, two newer rules matter. From 1 July 2026, OSFI exempts qualifying straight switches from the stress test at renewal. For eligible new homes, the housing-tax calculator now separates the federal first-time buyer rebate, Ontario's ENHR and Ontario's ONHAP payment. ONHAP fills only the federal HST left after other federal housing rebates; an HBP withdrawal is down-payment funding, not an additional tax rebate.
