- Extending your mortgage amortization at renewal can lower monthly payments by 10-20% but significantly increases total interest paid over the mortgage's life.
- Most Canadian mortgage terms are 5 years, but the amortization period can be reset up to 25 or 30 years (if initial down payment was less than 20%, CMHC rules may cap it at 25 years).
- A 20-year amortization on a $400,000 mortgage at 5.5% will save approximately $250 monthly compared to a 15-year amortization, but cost over $20,000 more in interest.
- OSFI B-20 guidelines and the mortgage stress test apply to new mortgages and some refinances, but generally not to uninsured renewals switching lenders, as of November 2024.
- Borrowers can often make lump-sum payments or increase regular payments on an extended amortization to reduce future interest, leveraging payment flexibility.
Deciding whether to reset your mortgage amortization at renewal depends on your current financial situation, future goals, and tolerance for paying more interest over the long term. Resetting extends the total time you have to pay off your mortgage, thereby reducing your monthly payment obligations.
Conversely, maintaining your original accelerated schedule, or even further shortening it, will result in higher monthly payments but save you a substantial amount in total interest paid over the life of the loan.
What is mortgage amortization, and how does it affect renewal?
Mortgage amortization is the total length of time, in years, it takes to pay off your mortgage in full, assuming consistent payments.
At renewal, while your mortgage 'term' (typically 1-5 years) is renegotiated, you also have the opportunity to adjust the remaining amortization period. For example, if you took out a 25-year mortgage 5 years ago, you now have 20 years remaining. At renewal, you could choose to keep that 20-year schedule, shorten it to 15 years, or extend it back out to 25 or even 30 years (subject to lender and CMHC rules for insured mortgages). This decision directly impacts your monthly payment amount and the total interest you will pay.
What are the benefits of extending my amortization at renewal?
The primary benefit of extending your amortization at renewal is a reduction in your monthly mortgage payments, providing immediate cash flow relief.
This can be particularly advantageous during periods of financial stress, such as job loss, reduced income, or unexpected expenses. It offers greater financial flexibility, allowing you to allocate funds to other essential needs, investments, or debt repayment. While it increases the total interest paid, it acts as a valuable safety net by lowering your mandatory housing costs, which can be critical during high-interest rate environments. This strategy can also free up cash for high-interest debts like credit cards, ultimately saving you more in the short term.
What are the disadvantages of resetting amortization to a longer term?
The main disadvantage of resetting your amortization to a longer term is paying significantly more interest over the life of your mortgage.
By spreading your payments over a longer period, less of each payment goes towards the principal in the early years, and more is consumed by interest. This also means you will be mortgage-free later in life, potentially impacting your retirement planning. While a longer amortization offers payment flexibility, it should be weighed against the long-term financial cost. For example, extending a $400,000 mortgage from 20 to 25 years at a 5.5% interest rate could add over $20,000 in total interest over that period, despite reducing monthly payments.
How does extending amortization affect total interest paid? (Worked Example)
Extending your amortization can drastically increase the total interest paid over the life of your mortgage.
Consider a homeowner renewing a mortgage with a remaining balance of $400,000 at a new interest rate of 5.5%.
If they choose to maintain their current 20-year amortization, their monthly payment would be approximately $2,729. Over the remaining 20 years, they would pay roughly $254,960 in interest.
However, if they extend their amortization back to 25 years, their monthly payment drops to approximately $2,467, a saving of $262 per month. But, over the 25-year period, the total interest paid would be approximately $340,100. This example shows that while the monthly payment is lower by $262, the total interest paid increases by approximately $85,140 ($340,100 - $254,960) over the life of the loan. This is a significant long-term cost for short-term payment relief.

What are the rules for amortization periods in Canada?
In Canada, the maximum amortization period for a new conventional (uninsured) mortgage is typically 25 years, though some lenders may offer up to 30 years for those with a down payment of 20% or more.
For high-ratio (insured) mortgages, where the down payment is less than 20% (e.g., CMHC insured), the maximum amortization period is capped at 25 years. At renewal, lenders generally allow you to extend the amortization up to the original maximum term you qualified for, or sometimes even longer (e.g., to 30 years if you initially qualified for 25 with 20%+ down), provided you still meet their lending criteria. OSFI B-20 guidelines do not restrict amortization length at renewal as strictly as they do for new mortgages or refinances, especially for existing clients.
Should I reset my amortization if I'm switching lenders at renewal?
If you are switching lenders at renewal and wish to reset your amortization, the new lender will likely treat this as a new mortgage application, which means you will undergo a fresh qualification process.
This includes the mortgage stress test (Bank of Canada's benchmark rate or contract rate + 2%, whichever is higher), credit checks, and income verification. As of November 2024, uninsured mortgage renewals that switch lenders will no longer need to re-qualify at the stress-test rate, which significantly eases the process for many Canadians. However, if you're looking to *extend* the amortization significantly beyond what was remaining, or if your financial situation has changed, the new lender will still assess your ability to carry the debt under their current guidelines. It's crucial to compare renewal offers from your existing lender against new offers, especially considering any associated costs like appraisal fees or legal fees when switching.
Comparing Amortization Strategies at Renewal
Understanding the trade-offs between different amortization strategies is key to making an informed decision at renewal. The choice should align with your immediate financial needs and your long-term wealth-building goals.
| Feature | Extend Amortization (e.g., 20 to 25 years) | Keep Original Amortization (e.g., 20 years) | Shorten Amortization (e.g., 20 to 15 years) |
|---|---|---|---|
| Monthly Payment | Lower | Moderate | Higher |
| Total Interest Paid | Higher | Moderate | Lower |
| Cash Flow | Improved | Stable | Reduced |
| Time to be Mortgage-Free | Longer | Original Schedule | Shorter |
| Financial Flexibility | High (can make prepayments) | Moderate | Lower |
| Ideal For | Budget strain, unexpected costs, other high-interest debt | Stable finances, balance of cost & payment | Aggressive debt repayment, high income stability |
How can I evaluate my options and make the best decision?
Evaluating your options requires a clear understanding of your current financial health, future income projections, and risk tolerance.
Consider using a mortgage renewal calculator to compare payments and total interest paid under different amortization scenarios. Reflect on whether you anticipate significant life changes (e.g., starting a family, career change, retirement) that might impact your income or expenses. If you extend your amortization for cash flow relief, remember that you can still make prepayments (lump sums or increased regular payments) if your financial situation improves, effectively shortening your amortization and saving on interest. However, if you are unsure, speaking with a licensed Canadian mortgage agent can provide personalized advice based on your unique circumstances. They can help you navigate the nuances of lender policies and interest rates to ensure your mortgage renewal strategy aligns with your overall financial plan.

Frequently asked
What happens if I don't reset my amortization at renewal?
If you don't reset your amortization, you will continue paying down your mortgage based on the remaining schedule. Your monthly payments will be recalculated with the new interest rate but will still aim to pay off your mortgage by the original end date.
Can I extend my amortization by more than 5 years at renewal?
Yes, at renewal, you can typically extend your amortization beyond the original remaining period, often up to 25 or even 30 years, depending on your lender's policies and whether your mortgage is insured. This will reduce your monthly payments.
Will extending my amortization affect my credit score?
Extending your amortization at renewal generally does not directly impact your credit score. However, reducing your monthly payments can improve your debt-to-income ratio, which could indirectly benefit your credit by making it easier to manage other debts.
Is it always better to pay off my mortgage faster by keeping a shorter amortization?
Financially, paying off your mortgage faster generally means you pay less total interest over time. However, it requires higher monthly payments, which might not be feasible if you have other pressing financial priorities or seek more cash flow flexibility.
Do I need to re-qualify for a mortgage if I extend my amortization at renewal?
If you renew with your existing lender and extend your amortization, you may not need to fully re-qualify, especially if the extension is modest. If you switch lenders or extend significantly, the new lender will likely require you to re-qualify, including stress testing your ability to pay.
What is the maximum amortization period allowed in Canada for an insured mortgage?
For insured mortgages (those with less than 20% down payment, often backed by CMHC), the maximum amortization period allowed in Canada is 25 years. Uninsured mortgages may sometimes be extended to 30 years by some lenders.
Can I extend my amortization now and then shorten it later?
Yes, if you extend your amortization at renewal, you typically retain the flexibility to make lump-sum payments or increase your regular payment amounts without penalty (up to your prepayment privileges). This allows you to shorten the effective amortization period later.
Will my lender automatically extend my amortization at renewal?
No, your lender will not automatically extend your amortization. They will typically offer you renewal terms based on your remaining amortization. You must actively request and negotiate to extend it if that is your preference.
Does OSFI regulate amortization periods at renewal?
OSFI's B-20 guidelines primarily target new mortgages and refinances. While they indirectly influence lender policies, existing clients renewing with their current lender often have more flexibility regarding amortization extensions compared to new borrowers or those switching lenders, particularly for uninsured mortgages.
What if I can't afford my payments at renewal with my original amortization?
If you can't afford your payments, extending your amortization is one viable strategy to reduce them and improve cash flow. You should also explore other options like negotiating a better rate, making lump-sum payments if possible, or consulting a mortgage professional for tailored advice.
