25 vs 30 Year Mortgage Amortization in Canada: 2026 Rules, Costs & Eligibility

Canadian homeowners and first-time buyers can achieve homeownership with down payments as low as 5% on properties priced up to $1.5 million (as of 2024) by leveraging mortgage loan insurance from Canada's three approved insurers: CMHC (Canada Mortgage and Housing Corporation), Sagen (formerly Genworth Canada), and Canada Guaranty. Each insurer plays a distinct role in the market — CMHC is a federal Crown corporation, while Sagen and Canada Guaranty are private-sector insurers — but all three provide lender protection that unlocks competitive rates and flexible terms for borrowers with smaller down payments. Qualifying requires passing the OSFI B-20 stress test at the higher of 5.25% or your contract rate plus 2%.

December 2024 mortgage reforms expanded insured mortgage access and eased renewals for millions of Canadians. Key changes include a stress-test exemption for uninsured mortgage straight switches, a higher insurable mortgage price cap of $1.5 million, and 30-year amortizations for first-time buyers and new-build purchases. CMHC (Canada Mortgage and Housing Corporation) insurance updates further support diverse borrowers, including self-employed Canadians and those pursuing energy-efficient homes.

Canada Mortgage and Housing Corporation (CMHC)-insured mortgages give Canadian homebuyers — especially first-timers — access to lower interest rates and smaller down payments than conventional mortgages require. With December 2024 reforms raising the insurable property value cap to $1.5 million and expanding 30-year amortization eligibility, insured mortgages are more powerful than ever. CMHC mortgage insurance premiums range from 2.8% to 4.0% depending on your down payment size; 0.6% is not a valid premium rate. Features like Portability and a 25% Green Home premium refund add further long-term value. This guide explains how insured mortgages work, who qualifies, and how to use them strategically in 2026.
