The amortization period — the total length of time to fully repay your mortgage — is one of the most consequential decisions a Canadian homebuyer makes. And in 2026, with new federal rules expanding 30 year amortization eligibility for first-time buyers and new construction purchasers, the 25 vs. 30 year debate has never been more relevant. Here’s a complete, number-driven comparison.
Term vs. Amortization: Understanding the Difference
These two concepts are routinely confused — and they’re fundamentally different:
- Mortgage term: The length of your current rate contract — typically 1 to 5 years. After the term ends, you renew.
- Amortization period: The total time to pay off the entire mortgage — typically 20 to 30 years. Consists of multiple terms.
A 5-year term on a 25-year amortization means you renew up to 5 times before the mortgage is paid off. Your amortization period determines your base monthly payment — your term determines the rate you pay.
25-Year vs. 30 Year Amortization: Monthly Payment Comparison
| Mortgage Balance | Rate | 25-Year Payment | 30-Year Payment | Monthly Savings |
|---|---|---|---|---|
| $450,000 | 4.04% | $2,374/mo | $2,143/mo | $231/mo |
| $600,000 | 4.04% | $3,165/mo | $2,857/mo | $308/mo |
| $750,000 | 4.04% | $3,956/mo | $3,571/mo | $385/mo |
The True Cost of 30 Year Amortization: Total Interest
| Mortgage Balance | 25-Year Total Interest | 30-Year Total Interest | Extra Interest (30-yr) |
|---|---|---|---|
| $450,000 | $262,200 | $321,500 | +$59,300 |
| $600,000 | $349,500 | $428,500 | +$79,000 |
| $750,000 | $436,800 | $535,600 | +$98,800 |
Who Is Eligible for 30 Year Amortization in 2026?
- First-time homebuyers purchasing any property with an insured mortgage (less than 20% down, property under $1M)
- All buyers of new construction — whether first-time or repeat buyers — with an insured mortgage
- Uninsured mortgages (20%+ down) already allowed 30-year amortization at most lenders — this is not new
- Repeat buyers on resale properties with insured mortgages remain capped at 25 years
The full eligibility criteria for 30 year amortization on insured mortgages is published by the CMHC 30-year amortization program page.
The Smart Strategy: Choose 30 Year Amortization, Pay Like 25
The optimal approach for many buyers: take the 30 year amortization for the lower mandatory payment (improving qualification and cash flow), but use prepayment privileges to make extra payments equivalent to a 25-year schedule. This provides payment flexibility during tight months while accelerating your payoff when cash flow allows — combining the best of both options.

Frequently Asked Questions
Who qualifies for 30 year amortization in 2026?
First-time homebuyers and buyers of new construction with an insured mortgage (less than 20% down) qualify for 30 year amortization in 2026. Repeat buyers purchasing resale properties with insured mortgages are still capped at 25 years. Uninsured mortgages (20%+ down) have long allowed 30-year amortization regardless of buyer type.
Is 30 year amortization a good idea?
It depends on your priorities. 30 year amortization lowers your monthly payment and can help you qualify for a larger mortgage, but it costs tens of thousands more in total interest over the life of the loan. Many buyers choose 30-year amortization for flexibility, then make extra prepayments to pay it off closer to a 25-year timeline.
