25 vs 30 Year Mortgage Amortization in Canada: Which Is Better? (2026)
Updated
The 25 vs 30-year amortization question is one of the most consequential mortgage decisions Canadians face — and the 2024 rule change that extended 30-year amortization to first-time buyers of new builds adds a new wrinkle. On a $500,000 mortgage at 5%, the difference is about $224/month in payments but nearly $94,000 in total interest over the life of the loan. Neither option is universally better: it depends on whether you value lower payments and cash-flow flexibility (30 years) or paying less total interest and building equity faster (25 years). The tables below break down the math for several price points.

Strategy: Best of Both Worlds
The smartest approach for many buyers is to take the 30-year amortization for qualification and flexibility, then voluntarily make payments at the 25-year level. This gives you the safety net of a lower required payment during tight months while still paying off the mortgage in 25 years when times are good. Most Canadian lenders allow 10–20% annual lump-sum prepayments and 10–25% payment increases without penalty — use these privileges aggressively. The key is discipline: if you take the 30-year and spend the difference instead of investing it, you’ll simply pay $94,000 more in interest with nothing to show for it.

The Investment Argument
Should You Invest the Payment Difference?
| 30-Year Payment Savings | $224/month |
| Invested at 7% for 25 years | ~$170,000 |
| Interest cost of 30 vs 25-year | ~$95,000 |
| Net benefit | ~$75,000 |
However: This assumes disciplined investing and 7% returns. Most people don’t actually invest the difference — they spend it.
Reality Check
Outcome
Likelihood
Actually invest difference monthly
Low for most people
Spend the “extra” cash flow
High
Result
30-year just costs more
Recommendation: Unless you’ll truly invest the difference, the 25-year usually wins.

The Bottom Line
For most Canadians with stable income, the 25-year amortization saves tens of thousands in interest and gets you debt-free sooner. The 30-year makes sense if you need the lower payments to qualify, want cash-flow flexibility in a high cost-of-living city, or will genuinely invest the payment difference. If you’re unsure, take the 30-year and make 25-year payments — you get flexibility without the extra cost.
