What Is a 30-Year Amortization?
Until August 2024, the maximum amortization period for an insured (high-ratio) mortgage in Canada was 25 years. That changed with federal mortgage reforms announced in the 2024 federal budget. Eligible buyers can now access insured mortgages with 30-year amortization periods, bringing monthly payments meaningfully lower.
To understand what this means in practice, it helps to understand the difference between your mortgage term and your amortization period. Your term is how long your current rate is locked in — usually 1 to 5 years. Your amortization is the full timeline for paying off the mortgage. You renew your term multiple times over the life of your amortization.
Who Qualifies for 30-Year Amortization?
The 30-year amortization is not available to everyone. As of the federal rule changes effective August 1, 2024, it applies to:
- First-time homebuyers purchasing any property type (new or resale), provided the mortgage is insured (down payment under 20%). The federal definition of a first-time buyer includes anyone who has not owned a home in the previous four calendar years, or who is purchasing with a first-time buyer spouse or common-law partner.
- Any buyer purchasing a newly constructed home — regardless of whether they are a first-time buyer — provided the mortgage is insured.
Conventional (uninsured) mortgages with a 20% or greater down payment are not subject to the same restrictions and have always allowed amortizations beyond 25 years at lender discretion. The new rules specifically expanded access to 30-year amortization for insured mortgages, where lenders had previously been capped at 25 years.
How Much Does a 30-Year Amortization Lower Your Payment?
| Purchase Price | Down Payment | Rate | 25-Year Monthly Payment | 30-Year Monthly Payment | Monthly Savings |
|---|---|---|---|---|---|
| $500,000 | 5% ($25,000) | 5.25% | ~$2,870 | ~$2,605 | ~$265/mo |
| $700,000 | 10% ($70,000) | 5.25% | ~$3,710 | ~$3,370 | ~$340/mo |
| $900,000 | 10% ($90,000) | 5.25% | ~$4,660 | ~$4,230 | ~$430/mo |
Approximate figures for illustration. Actual payments depend on exact rate, CMHC premium, and payment frequency.
The Trade-Off: More Total Interest
A lower monthly payment is appealing — but it comes at a cost. Extending your amortization by 5 years means you pay interest for 5 more years on your outstanding balance. Over the life of a large mortgage, this adds up significantly.
This doesn’t mean 30 years is wrong. For buyers who genuinely can’t qualify at the 25-year payment, or who can qualify but would be stretched uncomfortably thin, the lower payment can mean the difference between buying now and waiting years longer. The question is whether the trade-off is worth it given your specific situation.
Strategies to Reduce the Long-Term Cost
Choosing a 30-year amortization doesn’t mean you’re committed to paying for 30 years. Most mortgages allow prepayment privileges — the ability to make lump-sum payments or increase your regular payment above the minimum. Used consistently, prepayment privileges can significantly shorten your actual payoff timeline and reduce total interest, even if you’re amortized over 30 years.
- Increase your payment at each renewal to match what the 25-year payment would have been
- Apply lump-sum payments annually when your budget allows
- Choose accelerated bi-weekly payments, which add one extra monthly payment per year automatically
30-Year Amortization and CMHC Mortgage Insurance
If your down payment is less than 20%, your mortgage must be insured by CMHC (or an approved equivalent). CMHC charges a one-time premium based on your loan-to-value ratio, which is added to your mortgage balance. The 30-year amortization option is available under insured mortgages — you don’t lose access to CMHC insurance by choosing the longer period, and the premium rates are the same as for a 25-year insured mortgage.
One important restriction: CMHC-insured mortgages are only available for homes purchased below $1,500,000 (raised from $1,000,000 as of December 2024). Properties above that threshold require a minimum 20% down payment and do not qualify for the extended amortization under the insured rules. See New Mortgage Rules 2025 for full details.

Is a 30-Year Amortization Right for You?
It depends on your goals. A 30-year amortization makes the most sense when:
- You want to enter the market now rather than waiting to save a larger down payment
- Your income is solid but a 25-year payment leaves you uncomfortably tight month-to-month
- You plan to use the monthly savings for investing or building an emergency fund
- You’re a first-time buyer who qualifies and the lower payment meaningfully improves your quality of life
It makes less sense when you have strong cash flow, are buying for the long term, and prioritize paying the least total interest. In those cases, a 25-year amortization — possibly with accelerated payments — is the better financial move.
