Is It Worth Getting a 15 Year Mortgage in Canada 2025: Pros, Cons & Rate Math

Is It Worth Getting a 15 Year Mortgage in Canada 2025? The Short Answer

If you're weighing whether is it worth getting a 15 year mortgage in Canada 2025, the honest answer depends on three variables: your rate spread versus a 25-year amortization, your cash flow buffer, and how disciplined you are with prepayments. A shorter amortization isn't automatically "smart money" — it's a leverage decision. Below is the math most brokers won't walk you through.

The Rate Advantage: Where the 15-Year Term Actually Wins

In 2025, Canadian lenders typically price 15-year amortizations 10–25 basis points below comparable 25-year products, and some monoline lenders offer sharper discounts because shorter amortizations reduce their duration risk. On a $600,000 mortgage at 5.00% versus 5.20%, the 15-year schedule saves roughly $48,000 in interest over the life of the loan — before accounting for the faster principal paydown.

But here's the nuance: the 15 year mortgage in Canada isn't a product — it's an amortization attached to a standard 5-year term. You can often replicate the same payoff curve on a 25-year amortization by using the 20% annual prepayment privilege most lenders grant. If your lender allows it, the 15-year label is largely cosmetic.

The Cash Flow Trap: Why Shorter Amortizations Fail Stress Tests

A 15-year amortization on $600,000 at 5.00% costs about $4,744 monthly versus $3,508 on 25 years — a $1,236 gap. Under OSFI's B-20 stress test, you must qualify at the higher of your contract rate plus 2% or 5.25%, so the qualification burden compounds. In 2025's rate environment, that spread can push borrowers below their target purchase price or force a smaller down payment.

The real risk isn't the math — it's liquidity. Locking $1,200+ monthly into mandatory principal reduces your emergency reserve and investment capacity. If your TFSA or RRSP returns exceed your after-tax mortgage rate, the 15-year schedule is a negative-carry decision.

When a 15-Year Amortization Is Genuinely Worth It

Choose the shorter amortization if: you're within 10–12 years of retirement and want a debt-free exit; your income is stable and you hold 6+ months of expenses in reserve; or you'd otherwise spend the difference rather than invest it. For high-income borrowers in Ontario and BC facing large balances, the interest savings are material and the discipline is built in.

For everyone else, the smarter play in 2025 is a 25-year amortization with aggressive prepayments — you keep flexibility, match the 15-year payoff curve voluntarily, and preserve liquidity if rates or income shift.

Conclusion

So, is it worth getting a 15 year mortgage in Canada 2025? Yes — if you have the cash flow buffer, plan to stay put, and value forced discipline over investment upside. No — if the payment stretches you thin or you'd rather deploy capital elsewhere. Run both scenarios through a mortgage calculator at your actual quoted rate, then decide with numbers, not vibes.
