30-Year Amortization for Insured Mortgages in Canada
Updated April 2026. The federal government's 2024 mortgage reforms — phased in August and expanded December 15, 2024 — opened 30-year insured amortizations to first-time homebuyers and all new-build purchasers. Here's how it works and what it means at renewal.
Key Takeaways
- • August 1, 2024: 30-year insured amortizations became available to first-time buyers of newly built homes only.
- • December 15, 2024: Expanded to all first-time buyers (any property) and any buyer of a newly built home (first-time or not).
- • Insured cap raised simultaneously from $1M to $1.5M.
- • First-time buyer = no borrower has owned a principal residence in the prior 4 years (with a marriage/common-law breakdown exception).
- • Does not apply at insured refinance (insured refinances aren't permitted in Canada).
- • At renewal, your existing amortization is preserved on a straight switch — you can't stretch it to 30 years unless it was 30 at origination.

A Short History of Canadian Insured Amortization Rules
Canadian insured amortization limits have oscillated for decades. Before 2008, CMHC would insure mortgages up to 40 years. Following the global financial crisis, successive federal governments tightened the rules — down to 35 years, then 30 years, then 25 years by July 2012. That 25-year insured maximum held for over a decade.
The 2024 reforms reversed that trajectory for targeted cohorts. The policy goal was twofold: improve affordability for younger Canadians struggling to enter the market, and stimulate supply of newly built homes by providing a specific incentive for purchasers of new construction.
The Two Eligibility Paths in Effect Today
Path 1: First-Time Buyers
Since December 15, 2024, any first-time buyer can access a 30-year insured amortization regardless of whether the home is new construction or a resale.
Requirement: no borrower has owned a principal residence in the prior 4 years.
Path 2: New Construction
Any buyer purchasing a newly built home (not just first-timers) can access a 30-year insured amortization on the purchase.
Newly built = never previously occupied, including pre-construction condos and new detached homes.
What Counts as a "First-Time Homebuyer"?
The technical definition used by CMHC, Sagen, and Canada Guaranty requires that no borrower listed on the mortgage application has owned a principal residence in the prior 4 years. Key points:
- If you're applying jointly with a spouse or partner, both of you must meet the 4-year criterion.
- Owning investment property that was never your principal residence does not disqualify you (confirm with your lender — some have stricter interpretations).
- A marriage or common-law separation exception allows the departing spouse to qualify as a first-time buyer even if they owned the matrimonial home during the 4-year window.
- Foreign ownership periods can count, depending on the lender's underwriting policy.
Payment Impact: 25-Year vs. 30-Year Amortization
The monthly payment reduction from a 30-year amortization is meaningful but comes with long-term interest cost. Here's the math at April 2026 insured rates (~4.00% on a 5-year fixed):
| Mortgage Balance | 25-Year Payment | 30-Year Payment | Monthly Savings |
|---|---|---|---|
| $400,000 | $2,105 | $1,902 | $203 |
| $600,000 | $3,158 | $2,855 | $303 |
| $800,000 | $4,210 | $3,807 | $403 |
| $1,200,000 | $6,315 | $5,710 | $605 |
Calculations assume 4.00% contract rate, Canadian semi-annual compounding. Actual payments vary by lender.
How This Intersects With Your Mortgage Renewal
If you purchased your home under the 2024 rules with a 30-year insured amortization, that amortization continues through your first and subsequent renewals — as long as you do a straight switch or straight renewal. After 5 years in your first term, your remaining amortization at renewal would be 25 years, and the pattern continues.
What you cannot do at renewal is extend your amortization beyond your contractual schedule. If you originated on a 25-year amortization in 2022, you cannot renew into a 30-year amortization today — even if you'd otherwise meet the first-time-buyer criterion. Renewals preserve the existing amortization. See our renewal vs. refinancing guide for when you might want the flexibility of a refinance instead.
One narrow exception: the Canadian Mortgage Charter permits temporary amortization extensions up to 35 years on principal residences as a hardship relief measure. This is a genuine hardship provision — not a payment-reduction tool — and requires lender cooperation on a case-by-case basis.
Uninsured Mortgages Always Had 30-Year Access
An important clarification: borrowers with 20%+ down (conventional/uninsured) have been able to use 30-year amortizations for years — and some lenders offer 35-year uninsured amortizations. The 2024 changes only addressed insured mortgages. If you're renewing a conventional mortgage with 20%+ equity, the 30-year amortization question has always been on the table for refinances, subject to your lender's underwriting and the stress test.
Long-Term Cost: The Trade-Off of Longer Amortizations
Reduced monthly payments are attractive, but 30-year amortizations increase total interest paid over the life of the loan substantially. On a $600,000 mortgage at 4.00% carried to full term:
- 25-year amortization: Total payments ≈ $947,400. Total interest ≈ $347,400.
- 30-year amortization: Total payments ≈ $1,027,800. Total interest ≈ $427,800.
- Extra interest over life of loan: ~$80,400 for the 30-year option.
Most Canadians don't carry a single mortgage to full amortization — life events, rate changes, and home sales intervene. But the total cost picture matters when deciding whether to maximize qualification with a 30-year term or opt for 25 years if affordability allows.
Frequently Asked Questions
Who can get a 30-year amortization on an insured mortgage in Canada? +
As of December 15, 2024, two groups can access 30-year insured amortizations: (1) all first-time homebuyers, regardless of property type, and (2) any buyer purchasing a newly built home, regardless of whether they are first-time buyers. Previously, from August 1, 2024, only first-time buyers of new construction qualified. The insured mortgage cap was simultaneously raised to $1.5 million.
What defines a 'first-time homebuyer' for the 30-year rule? +
Canada Mortgage and Housing Corporation (CMHC) defines a first-time buyer as someone where no borrower on the application has owned a principal residence in the prior 4 years. There is a specific exception for people separating from a marriage or common-law partnership, who may qualify even if they owned a home during that period. All co-borrowers on the mortgage must meet the criteria.
Does the 30-year amortization apply at refinance? +
No. Default-insured refinances are not permitted in Canada — insurance applies to purchases and certain very limited circumstances only. If you want a 30-year amortization at refinance, you must refinance as a conventional (uninsured) mortgage, which requires 20% equity. Uninsured borrowers have long been able to use 30-year amortizations.
Does 30-year amortization apply at renewal? +
Yes, but only if your mortgage was originally set up on a 30-year amortization under the rules in effect at origination. Straight renewals preserve your existing amortization. You cannot extend from 25 to 30 years at renewal to lower payments — that would require a refinance, which triggers the stress test and, for insured loans, isn't permitted.
Why was the 30-year amortization expanded? +
The December 2024 expansion was part of what the federal government called the 'Boldest Mortgage Reforms in Decades.' The goal was to improve affordability for younger buyers being priced out by high home values and to stimulate new construction supply. Longer amortizations reduce monthly payments (at the cost of more total interest over the life of the loan), helping buyers qualify under the stress test at today's rates.
What's the payment impact of 30-year vs. 25-year amortization? +
On a $600,000 insured mortgage at 4.00%, the monthly payment is roughly $3,160 on a 25-year amortization versus $2,855 on a 30-year — a savings of $305/month, or about 9.6%. Total interest paid over the life of the loan is meaningfully higher with the 30-year (roughly $428,000 vs. $348,000 if you carried it to full amortization), but most borrowers renew long before reaching that point.
