Key Takeaways
- Amortization is the total time it takes to pay off your mortgage — most Canadians choose 25 or 30 years.
- Your 'term' (often 5 years) is separate from amortization; it's how long you're locked into your current contract.
- A longer amortization lowers your monthly payment but costs more in total interest over the life of the loan.
- Insured mortgages (down payment under 20%) are typically capped at a 25-year amortization in Canada.
- Reviewing your amortization at renewal — or after major income changes — can free up cash flow or reduce interest costs.
'Amortization', another scary mortgage term… do not fret! The concept of amortization is actually quite straightforward. Amortization is simply how long it will take you to pay off your mortgage according to your mortgage contract. The length of amortization is agreed upon between you and your lender — a common amortization period is 25 years, but it can often take 30 years (or even 35 years depending on which type of lender you arranged your mortgage with).
'Amortization' vs. 'Term'
The 'term' of your mortgage is also a measure of time, but only for a segment of your mortgage. Whereas the amortization period of your mortgage is the entirety of time it will take to pay it off, the term of your mortgage is the amount of time you are contractually committed to it.
For example:
When the term of your mortgage is close to maturing, it means a renewal is on the horizon! During your renewal, your licensed mortgage broker will assist you with re-evaluating whether restructuring your amortization period may be in your best financial interest.
If you would like to refinance your mortgage ahead of the maturity date, it may be a possibility, but it can come at a cost (pre-payment penalties).
How Amortization Affects Your Payments
Choosing a longer amortization period means your mortgage payments will be spread over more time, causing your monthly payments to decrease.
The reverse is true for a shorter amortization period. Less time to pay off your mortgage means you'll be required to fit in higher payments each month.
So why doesn't everybody choose a longer amortization period and enjoy lower monthly payments?
Your mortgage agreement is subject to interest by your lender. If it takes you longer to pay off your principal balance, it may end up costing you more as you'll also be paying a greater amount of interest in the long run.
Which Length of Amortization Should I Choose?
There is no one-answer-fits-all. Each borrower's mortgage needs are different from the next. Your licensed mortgage broker will chat with you regarding your lifestyle and goals to determine which amortization will save you the most money and be the most suitable to your needs.
Not everybody benefits from lower monthly payments. For example:
Overall, a longer amortization period may cost you more in the long run, but it also means you'll have the opportunity to build home equity along the way. Your investment in your home equity has potential to outweigh your interest costs from a longer amortization — it's all a matter of subjective perspective!
How Your Amortization Period Is Determined
As with any decisions regarding your mortgage, your amortization period is a fine balance between what you would like to receive and what your lender is willing to give. There are some aspects a lender may consider when assessing what amortization period they will approve:

Frequently Asked Questions
What is a mortgage amortization period?
The amortization period is the total length of time it will take to pay your mortgage down to zero, assuming payments stay the same. In Canada the most common amortization periods are 25 and 30 years, and some non-insured lenders allow up to 35 years.
What is the difference between amortization and mortgage term?
Amortization is the full payoff timeline for the loan. The term is the length of your current contract with the lender — usually 1 to 5 years — after which you renew the remaining balance at new rates and conditions.
Does a longer amortization cost more?
Yes. Stretching payments over more years lowers the monthly payment but increases total interest paid, because the principal is reduced more slowly.
What is the maximum amortization on an insured mortgage in Canada?
If your down payment is under 20%, the mortgage must be insured and the amortization is generally capped at 25 years, with a limited 30-year option for qualifying first-time buyers of new builds.
Can I change my amortization later?
Often yes. At renewal you can usually shorten or extend the amortization within lender limits, and lump-sum prepayments effectively shorten it. Mid-term changes may trigger prepayment penalties.
