25 vs 30 Year Amortization in Canada: What Does 5 Extra Years Cost?
Since December 15, 2024, 30-year amortization on insured mortgages is available only to first-time buyers or buyers of newly built homes. Everyone else with less than 20% down stays at 25 years maximum. On a $640,000 mortgage at 4.59%, stretching to 30 years drops the payment by about $313/month — but costs over $100,000 in extra lifetime interest.
Who can get 30 years in 2026
| Mortgage type | Max amortization |
|---|---|
| Insured, first-time buyer (never owned, or no owned principal residence in last 4 years, or marriage breakdown) | 30 years |
| Insured, newly built home (any buyer) | 30 years |
| Insured, everyone else | 25 years |
| Uninsured (20%+ down) | Up to 30 years at many lenders, some offer 35 |
Three conditions define the insured 30-year expansion:
- First-time buyer or new build only. Repeat buyers of resale homes with less than 20% down are capped at 25 years.
- Price cap raised to $1.5M (was $1M), so the insured market now covers most of the Greater Toronto and Vancouver first-time buyer range.
- +0.20% CMHC premium surcharge for 30-year insured mortgages, on top of the standard premium for your loan-to-value band.
Uninsured borrowers (20%+ down) were never part of the December 2024 change — many lenders already offered 30 years, and some go to 35. But note: federally regulated lenders stress-test 30-year+ amortizations more conservatively in some policies, so ask your lender how amortization length affects qualifying.
The worked example: $640,000 at 4.59%
| 25-year amortization | 30-year amortization | |
|---|---|---|
| Monthly payment | ~$3,574 | ~$3,261 |
| Payment difference | — | ~$313/month lower |
| Total interest paid | ~$432,000 | ~$534,000 |
| Extra interest for 30 years | — | ~$102,000 |
The 30-year option frees up roughly $313 a month — money that lowers your GDS/TDS ratios and can push a first-time buyer over the qualifying line. That is exactly why the policy exists: payment qualification, not wealth building. Over the full life of the mortgage, those extra five years of interest payments total over $100,000 more.
When the trade makes sense — and when it doesn't
- Makes sense: you need the lower payment to qualify under the stress test, or the monthly cash flow genuinely changes what you can afford today. You can always make lump-sum prepayments against a 30-year mortgage — most lenders allow 15–20% annual prepayment without penalty.
- Doesn't make sense: you comfortably qualify at 25 years and just prefer the lower payment. The $313/month you "save" becomes over $100,000 of extra interest. If you take 30 years for qualifying headroom, set up automatic prepayments to mimic the 25-year schedule once you're comfortable.
One more wrinkle: the +0.20% CMHC surcharge on 30-year insured mortgages is added to your premium and rolled into the loan, so it compounds slightly into the total.
Frequently asked questions
I owned a home 6 years ago and sold it. Am I a first-time buyer for the 30-year rule?
Yes. The definition is: never owned, OR have not owned a principal residence in the last 4 years, OR went through a marriage breakdown. Six years since owning qualifies you.
Does the 30-year option apply to investment properties?
No. The 30-year insured rule is for owner-occupied purchases by eligible buyers. Insured mortgages are for principal residences.
I'm putting 20% down. Can I get 30 years?
The insured 30-year rules don't apply to you at all — you don't need mortgage insurance. Many uninsured lenders offer 30-year amortization, and some offer 35. Your lender's own policy is the only constraint.
Does the +0.20% CMHC surcharge apply every year?
No — it is a one-time addition to your CMHC insurance premium at purchase (rolled into the mortgage amount), not an annual charge. The "surcharge" raises the premium you pay once, based on your loan-to-value band.
