With interest rate hikes, homeowners are facing the potential detonation of a financial bomb tied to their mortgages, the trigger rate. Let’s get into how a trigger point on a fixed-payment, variable mortgage can have such a strong impact on Canadians:
Impact of Interest Rate Hikes
Rising interest rates are inching homeowners closer to the trigger point of their mortgage, potentially impacting tens of thousands of Canadian homeowners with fixed-payment variable-rate mortgages. As interest rates increase, the mortgage payment may no longer cover the interest being charged, resulting in deferred interest added to the principal balance.
Financial Burden for Variable Rate Mortgage Holders
The Bank of Canada’s interest rate hikes could significantly increase the financial burden for variable-rate mortgage holders. RBC estimates that around 80,000 variable mortgages will be impacted by the interest rate hikes, potentially leading to a substantial increase in monthly payments for Canadians.

Fixed Payment, Variable Mortgages
Trigger rates can occur for customers who have fixed payment, variable rate mortgages. First, it’s important to understand that in a variable rate mortgage, the interest rate can change over time. This rate typically fluctuates based on a benchmark interest rate, like the prime rate set by lenders, which means it can go up or down during the term of the mortgage. This makes the mortgage variable.
Despite the variable interest rate, the amount of your monthly payment remains fixed. This is a key feature of a fixed payment, variable rate mortgage. Your monthly mortgage payment amount doesn’t change even when interest rates fluctuate. This makes the mortgage fixed payment.
When interest rates go down, more of your fixed payment goes towards paying off the principal of the loan, which can help you pay off your mortgage faster. However, when interest rates rise, a larger portion of your payment goes towards the interest, and less towards the principal. This could slow down the rate at which you build equity in your home.

Interest Rate Cap
Some fixed payment, variable rate mortgages have an interest rate cap. This means that even if interest rates rise to a certain level, your payments won’t change. However, if rates rise above this cap, your monthly payment may need to be adjusted to ensure the mortgage is paid off within the agreed term.
Fixed Payment, Variable Mortgages: Benefits and Risks
Fixed payment, variable rate mortgages offers the predictability of a fixed monthly payment, which can be easier for budgeting. However, there’s a risk that if interest rates rise significantly, you might end up with a smaller portion of your payment going towards the principal, which could extend the time it takes to pay off your mortgage or require a payment adjustment. Further, if interest rates rise high enough, the trigger rate could occur.
Fixed Payment Variable Rate Suitability
Fixed payment, variable rate mortgages might be suitable for someone who prefers the certainty of knowing exactly what their payment will be each month, but is also comfortable with the potential changes in how much of their payment is going towards the principal versus interest.
Impact of Rising Rates
Rising interest rates are inching homeowners closer to the trigger point of their mortgage, potentially impacting tens of thousands of Canadian homeowners with fixed payment variable rate mortgages. As interest rates increase, the mortgage payment may no longer cover the interest being charged, resulting in deferred interest added to the principal balance.
The trigger rate is reached when the minimum required principal payment towards the mortgage is not being met, a strategy employed by Canadian banks for protection. Rising interest rates could lead to payment adjustments. A trigger rate of 5.28% could cause payment adjustments if Bank of Canada’s interest rate increases, ensuring that amortization doesn’t exceed the original term.
Options for Dealing with Impact
Lenders may offer three options to mitigate the impact:
- Increase monthly payments
- Switch to a fixed rate mortgage
- Pay a lump sum.
However, interest rate hikes may still cause financial difficulties for Canadian homeowners, especially variable rate mortgage holders with different trigger rates.
As interest rates climb, Canadian homeowners must be prepared for potential payment adjustments. Consulting with mortgage lenders and staying informed about the impact of interest rate hikes is crucial for financial planning and stability.
