Should I Change My Amortization at Renewal in Alberta?
Short answer
It depends on your cash flow and goals. Shortening amortization raises your payment but cuts total interest. Extending it lowers the payment but costs more over time. At renewal you can often adjust amortization with your current lender without a full refinance, within insurer and lender limits.
The plain-English version
Amortization is the total time to pay off the mortgage. Each renewal, your remaining amortization is shorter than before unless you extend it. Shortening (for example from 20 years to 15) increases your payment but builds equity faster. Extending (for example back to 25 years) reduces the payment but adds interest over the life of the loan.
Federal rules cap amortization at 25 years for insured mortgages and 30 years for uninsured mortgages on new high-ratio loans; at renewal, extensions are usually limited to what you already had or what your lender allows on uninsured files. You cannot always stretch back to 30 years if you are currently at 18.
Alberta-specific considerations
- Alberta households with variable income (construction, agriculture, oil and gas) sometimes extend amortization for cash-flow relief — but should weigh the long-term interest cost.
- If your home value rose in Calgary or Edmonton, a shorter amortization may be easier to carry because your balance is lower relative to income.
- Switching lenders at renewal may limit how much you can change amortization if the new lender applies current policy rules.
Example scenario
At renewal your balance is $290,000 with 18 years left at 5.4%. Keeping 18 years gives a payment of about $2,090/month. Shortening to 15 years raises it to roughly $2,360/month but saves about $28,000 in interest over the life of the loan. Extending to 22 years drops the payment to about $1,890/month but adds roughly $35,000 in interest — planning estimates only.
Common mistakes to avoid
- Extending amortization for a lower payment without calculating total interest over the extra years.
- Assuming you can always reset to a 30-year amortization at renewal.
- Shortening amortization so aggressively that one income shock makes payments unmanageable.
- Changing amortization and rate at the same time without isolating what drives the payment change.
