How does amortization affect my mortgage?

Amortization represents the total time it takes to fully repay your mortgage.

Key Points

  • Your lender sets the maximum time you have to pay off your mortgage.

  • Lenders try to keep the average mortgage payoff time shorter than the maximum allowed.

  • The time you take to pay off your mortgage affects your monthly payments and how quickly you build equity in your home.

Extending Your Mortgage Amortization at Renewal in Canada: 2026 Rules, Costs & Options

Related Questions

How does the stress test affect my 2026 renewal options?

Same-lender renewals and uninsured straight switches (OSFI, November 21, 2024) are exempt from the prescribed MQR. A refinance, an insured switch, or any increase in loan amount still requires the stress test — greater of 5.25% or contract + 2%.

What's the difference between insured and uninsured mortgage renewals?

Insured mortgages face stricter CMHC/Sagen constraints while uninsured mortgages enjoy flexible OSFI-only guidelines.

Should I consider switching lenders or negotiate with my current lender?

Your switching decision hinges on rate differential versus requalification risk, with break-even analysis determining optimal strategy.

When should I start my mortgage renewal process?

Start your renewal process 120-180 days before your current term expires to maximize your strategic options.

$500,0005%30~$2,684.11~$466,279

As you can see, extending the amortization from 25 to 30 years saves about $239 each month, but adds about $89,279 to the total interest paid. For a $500k mortgage, this can drastically change the decision-making process.
