40-Year Mortgages for First-Time Homebuyers?

For many young Canadians, buying a first home has become a frustrating math problem. Even when a household earns a steady income and has saved for years, the monthly mortgage payment can still put homeownership out of reach.

Some mortgage brokers believe the solution is to give first-time buyers considerably more time to repay their loans. They propose allowing mortgage amortization periods of up to 40 years. Proponents claim this approach would lower monthly payments and save buyers hundreds of dollars. Mortgage professionals supporting this proposal have presented it to federal lawmakers, arguing that current lending rules leave too many qualified buyers on the sidelines.

However, critics of this extension argue that while longer mortgages reduce monthly payments, they also dramatically increase lifetime interest costs and slow the process of building home equity.

Proponents of the 40-year proposal cite an August 2026 illustration based on a $425,000 property bought with a 20% down payment. The remaining $340,000, borrowed at 4.59%, would result in a monthly payment of about $1,899 with a 25-year amortization. Extending the repayment term to 30 years would reduce the payment to roughly $1,732, while a 40-year schedule would bring it down to about $1,539, saving about $360 per month compared to the 25-year option, or more than $4,300 over 12 months.

For a young household managing childcare, transportation, insurance, and rising living costs, this difference could provide meaningful relief. It might also allow some applicants to meet lenders’ affordability requirements more comfortably.

However, skeptics of the 40-year amortization proposal argue that the illustration assumes the same interest rate throughout the repayment period. This assumption is not guaranteed, as Canadian mortgage rates can change when borrowers renew their loans. Critics contend that this uncertainty could undermine the assumed savings.

Using the same illustration, critics argue that under the 25-year repayment schedule, the estimated total interest would be $229,656; over 40 years, it would rise to $398,593. That’s an additional $168,937 in interest, even though the original mortgage amount remains the same.

Furthermore, one of the biggest misconceptions about extending amortization periods is that a smaller payment automatically ensures mortgage approval. Critics say this is not true. A longer amortization may seem more affordable because it spreads principal repayment over more years. However, applicants must still meet income, credit, and debt-service requirements through the stringent “stress test.”

Is the 40-year option entirely new? No, it has been experimented with in the past and was offered by some brokers as recently as 2008. The federal government discontinued it when it reduced the maximum amortization period for all government-backed mortgages from 40 to 35 years. Additional tightening eventually brought the insured maximum down to 25 years for most borrowers before the recent expansion to 30 years.

In conclusion, most financial experts and economists believe that if the government is committed to addressing the housing crisis, it should actively consider and debate all options without prejudice, rather than dismissing them outright. The longer amortization period should also be part of that discussion.
