25 vs 30 Year Mortgage Amortization in Canada: Which Is Better? (2026)

Updated

The 25 vs 30-year amortization question is one of the most consequential mortgage decisions Canadians face — and the 2024 rule change that extended 30-year amortization to first-time buyers of new builds adds a new wrinkle. On a $500,000 mortgage at 5%, the difference is about $224/month in payments but nearly $94,000 in total interest over the life of the loan. Neither option is universally better: it depends on whether you value lower payments and cash-flow flexibility (30 years) or paying less total interest and building equity faster (25 years). The tables below break down the math for several price points.

Why 30-Year Helps You Qualify

Factor Impact
Lower payment Improves GDS/TDS ratios
Stress test Still applies at contract rate + 2%
Same income Qualifies for larger mortgage

Pros and Cons

25-Year Amortization

Pros Cons
Pay off mortgage 5 years sooner Higher monthly payments
Save $75,000-130,000+ in interest Tighter monthly cash flow
Build equity faster May qualify for less
Own home outright earlier Less financial flexibility

30-Year Amortization

Pros Cons
Lower monthly payments Pay more interest overall
Easier to qualify 5 more years of payments
More cash flow flexibility Slower equity build
Can accelerate payments if desired May take longer to be debt-free

Strategy: Best of Both Worlds

The smartest approach for many buyers is to take the 30-year amortization for qualification and flexibility, then voluntarily make payments at the 25-year level. This gives you the safety net of a lower required payment during tight months while still paying off the mortgage in 25 years when times are good. Most Canadian lenders allow 10–20% annual lump-sum prepayments and 10–25% payment increases without penalty — use these privileges aggressively. The key is discipline: if you take the 30-year and spend the difference instead of investing it, you’ll simply pay $94,000 more in interest with nothing to show for it.

Get 30-Year, Pay Like 25-Year

Approach Result
Take 30-year amortization Qualify for more, lower required payment
Make 25-year-equivalent payments Pay off in 25 years anyway
Flexibility Can drop to 30-year payment if needed

Example

Factor Amount
Mortgage $500,000 at 5%
30-year payment $2,684
25-year payment $2,908
Extra monthly $224
If paid like 25-year Same cost as 25-year
Flexibility Can pay $2,684 if tight month

Prepayment Privileges

Lender Feature Typical
Annual lump sum 10-20% of original mortgage
Payment increase 10-25% more per payment
Double-up payments Make extra payments

Use these to pay off 30-year faster without committing to 25-year payment.

Who Should Choose Which?

Choose 25-Year If…

Factor Why
Stable, high income Can afford payments comfortably
Want to minimize interest Saves $75,000-130,000+
Planning to stay long-term Build equity faster
Near retirement Want mortgage paid before retiring
Don’t need max borrowing Already qualify for what you need

Choose 30-Year If…

Factor Why
Need lower payments Cash flow flexibility
Need to qualify for more Increases borrowing power
Variable income Buffer in lean months
First-time buyer, new build Take advantage of new rules
Plan to invest difference Potential higher returns

The Investment Argument

Should You Invest the Payment Difference?

| 30-Year Payment Savings | $224/month | | Invested at 7% for 25 years | ~$170,000 | | Interest cost of 30 vs 25-year | ~$95,000 | | Net benefit | ~$75,000 |

However: This assumes disciplined investing and 7% returns. Most people don’t actually invest the difference — they spend it.

Reality Check

Outcome Likelihood
Actually invest difference monthly Low for most people
Spend the “extra” cash flow High
Result 30-year just costs more

Recommendation: Unless you’ll truly invest the difference, the 25-year usually wins.

Impact on Other Goals

Goal 25-Year Impact 30-Year Impact
Retirement savings Less monthly cash for RRSP More monthly cash available
Emergency fund Harder to build Easier to build
Home equity Builds faster Builds slower
Financial freedom Sooner (debt-free earlier) Later

The Bottom Line

For most Canadians with stable income, the 25-year amortization saves tens of thousands in interest and gets you debt-free sooner. The 30-year makes sense if you need the lower payments to qualify, want cash-flow flexibility in a high cost-of-living city, or will genuinely invest the payment difference. If you’re unsure, take the 30-year and make 25-year payments — you get flexibility without the extra cost.
