In Canada, blend and extend is a mortgage refinancing option offered by some lenders that allows homeowners to extend their mortgage term and blend their current mortgage interest rate with a new interest rate. This option is often used by homeowners who want to take advantage of lower interest rates without breaking their existing mortgage contract, which could result in costly penalties.
Blend and Extend and Your Mortgage

How Blend and Extend Works
Blend and extend works by doing the following:
- Blending the interest rates of more than one term or offering
- Extending the term
- Avoiding penalties
Blending the Interest Rates
The lender combines (or blends) the current mortgage interest rate with the new, lower interest rate available on the market. The resulting rate is somewhere between the old and new rates, offering a compromise that reduces the interest burden without fully switching to the new rate.
Extending the Term
Along with blending the rates, the homeowner extends the mortgage term, effectively lengthening the duration over which the mortgage will be repaid. This extension can reduce the monthly payment amounts since the loan is spread out over a longer period.
Avoiding Penalties
One of the primary advantages of a blend and extend option is that it allows homeowners to refinance at a more favorable rate without incurring the prepayment penalties that would typically apply if they were to break their current mortgage contract early.
Benefits of Blend and Extend
There are many benefits to being able to blend and extend (if the lender allows it for your mortgage product):
- Lower interest rates
- Flexible repayment
- Avoid mortgage breakage penalties
Lower Interest Rates
By blending the current and new rates, homeowners can lower their overall interest rate, reducing the amount of interest paid over the life of the mortgage.
Flexible Repayment
Extending the term can lead to lower monthly payments, making it easier for homeowners to manage their cash flow.
Avoidance of Breakage Fees
Since the existing mortgage is not fully discharged but rather modified, homeowners can avoid the hefty penalties that usually come with breaking a mortgage contract early.

Considerations
When doing a ‘blend and extend’, you should consider the following:
- Longer debt period
- Partial rate reduction
- Complexity
Longer Debt Period
While extending the mortgage term can reduce monthly payments, it also means that the homeowner will be in debt for a longer period, which may result in paying more interest overall despite the lower rate.
Partial Rate Reduction
The blended rate is usually higher than the current market rate, meaning homeowners won’t benefit fully from the lowest available rates. This option is often a compromise rather than the most cost-effective solution.
Complexity
Not all lenders offer blend and extend options, and the calculations involved in determining the blended rate can be complex. It’s important for homeowners to clearly understand how the new rate and term will impact their overall financial situation.
Blend and Extend and Your Mortgage
Blend and extend is a strategic tool for managing mortgage debt, especially when interest rates fluctuate. It allows homeowners to adapt their mortgage to changing financial conditions without the downsides of breaking the mortgage contract. This option can be particularly beneficial in a declining interest rate environment, where homeowners want to lock in lower rates while maintaining flexibility.
Summary
In summary, blend and extend is a refinancing option in Canada that allows homeowners to blend their current mortgage rate with a new rate and extend the mortgage term. This can help reduce interest costs and monthly payments without incurring penalties for breaking the mortgage contract. However, it involves trade-offs, including a potentially longer debt period and only partial benefit from lower interest rates. Homeowners considering this option should weigh the benefits and costs carefully.
