Canada's 30-year amortization reform: who qualifies and what it changes in 2027
Canada expanded 30-year insured mortgage amortizations in August 2024 — first for new construction buyers, then for all first-time buyers. This guide covers who qualifies under the 2027 rules, how the extended amortization affects payments and total interest, and what CMHC insurance premium applies.
Canada's August 2024 mortgage reform expanded access to 30-year insured amortizations for the first time since 2012 — initially for new construction, then extended to all first-time buyers in December 2024. Here is how the rules work in 2027, what they cost, and who benefits most.
Who qualifies: 30-year insured amortization eligibility
- First-time home buyers — any property type
- Any buyer purchasing a newly built home
- Purchase price under $1.5 million
- Minimum 5% down payment
- Passes OSFI B-20 stress test at contract rate + 2% or 5.25%
- Repeat buyers purchasing resale homes
- Rental / investment properties
- Refinances (max 25-year amortization remains)
- Purchase prices at or above $1.5 million
Payment and cost comparison: 25 vs 30 years
| Mortgage amount | Rate | 25-yr payment | 30-yr payment | Monthly saving | Extra interest (30 yr) |
|---|---|---|---|---|---|
| $400,000 | 5.5% | $2,432 | $2,271 | $161 | ~$35,000 |
| $500,000 | 5.5% | $3,040 | $2,839 | $201 | ~$44,000 |
| $600,000 | 5.5% | $3,648 | $3,407 | $241 | ~$53,000 |
Approximate figures. Extra interest assumes the full 30-year term is held — accelerated payments or renewals at lower rates reduce the gap. Use the Canadian mortgage calculator for exact numbers.

Common questions
Who qualifies for a 30-year insured mortgage in Canada in 2027?
As of December 15, 2024, 30-year insured amortizations are available to: (1) first-time home buyers purchasing any property, and (2) any buyer (first-time or not) purchasing a newly built home. The property must qualify for CMHC-insured financing (purchase price under $1.5 million, minimum 5% down). The Department of Finance Canada announcement outlines the full eligibility criteria.
How much does a 30-year amortization reduce monthly payments vs 25 years?
On a $500,000 insured mortgage at 5.5%, extending from 25 to 30 years reduces the monthly payment by approximately $220 (from ~$3,040 to ~$2,820). However, total interest paid over the full term increases by roughly $40,000–$60,000. The CMHC mortgage calculators let you run exact comparisons for your purchase price and rate.
Does the CMHC premium change with a 30-year amortization?
Yes — CMHC applies a 20-basis-point surcharge (0.20%) to the insured premium for amortizations over 25 years. For a $500,000 purchase with 5% down ($475,000 insured), the standard premium at 95% LTV is 4.00% ($19,000). With a 30-year amortization, the premium becomes 4.20% ($19,950) — an additional $950 financed into the mortgage. The CMHC premium rate table shows all current rates by LTV tier.
Can repeat buyers use 30-year insured mortgages for resale homes?
No — repeat buyers purchasing resale (previously owned) homes are still limited to 25-year insured amortizations under 2027 rules. Only first-time buyers and buyers of new construction qualify for 30-year insured amortizations on resale properties. Repeat buyers can obtain 30-year amortizations on uninsured mortgages (purchase prices above $1M or down payments above 20%), but those carry higher rates and no CMHC backing. The Finance Canada reform announcement specifies the eligibility conditions.
How does the stress test apply to 30-year insured mortgages?
The OSFI B-20 stress test applies regardless of amortization length. Borrowers must qualify at the higher of the contract rate plus 2%, or 5.25%. Since the 30-year term reduces the payment used for qualification, it does modestly increase the purchase price borrowers can qualify for — but the stress test rate still sets the ceiling. The OSFI B-20 residential mortgage underwriting guideline governs qualification requirements.
How does Canada's 30-year amortization compare to US mortgage terms?
In the US, 30-year fixed mortgages have always been the dominant product — available to any borrower without restrictions by buyer type or construction status. Canada's insured market was capped at 25 years from 2012 until the 2024 reform. The key structural difference: Canadian insured mortgages carry mortgage default insurance (CMHC) that protects lenders, while US mortgages use PMI that protects only the lender and can be cancelled. The CMHC mortgage insurance overview explains the Canadian system.
