Fixed vs. Variable Mortgages: Which is Right for You?

Tim Lyon • September 25, 2025

When arranging a mortgage, one of the first decisions you’ll need to make is whether to go with a fixed or variable rate. Both options have their own benefits and challenges, and understanding the differences will help you choose the one that fits your financial situation best.


In this post, we’ll break down the differences between fixed and variable mortgages, how they’re priced, the pros and cons of each, and what you should consider before making a decision.


What are Fixed and Variable Mortgages?

Fixed Rate Mortgage: Your interest rate stays the same for the entire mortgage term. That means your monthly payments won’t change, making budgeting more predictable.


Variable Rate Mortgage: Your interest rate changes during the term. There are two main types:

  • Variable Rate Mortgage (VRM): Your payment amount stays the same, but how much goes toward principal vs. interest changes as rates move.
  • Adjustable Rate Mortgage (ARM): Your payment amount itself changes when rates move.


How Do Fixed and Variable Mortgages Work?

Fixed
  • Your rate is set when you sign your mortgage contract.
  • Payments remain consistent, regardless of whether interest rates rise or fall.
  • Fixed rates are heavily influenced by the Canadian 5-year bond yield.
Variable
  • Your rate is tied to your lender’s prime rate, which follows the Bank of Canada’s overnight lending rate (reviewed 8 times a year).
  • Lenders usually offer a discount from prime, such as Prime – 0.4%.
  • You can often lock into a fixed rate at any time (though usually for a term equal to or longer than what’s left on your mortgage).


Penalties for Breaking Your Mortgage

Fixed
  • The greater of three months’ interest or the Interest Rate Differential (IRD). IRD can be very costly if rates have dropped since you signed.
Variable
  • Always three months’ interest — simpler and usually less expensive.


Pros and Cons

Fixed Rate Pros:
  • Predictable payments, easier budgeting
  • Protection if rates rise
  • Currently about 1% lower than variable, meaning you may qualify for more
Fixed Rate Cons:
  • More penalty risk if you break the mortgage early
  • You miss out if rates fall


Variable Rate Pros:
  • Benefit if rates decrease
  • Less penalty risk(3 months’ interest)
  • Option to lock into fixed at any time
Variable Rate Cons:
  • Payments (ARM) or interest portion (VRM) can rise if rates go up
  • Less predictable for budgeting
  • Lock-in rates may not always be the best available



Quick Summary

• Fixed mortgages = stable, predictable, tied to bond yields, but more penalty risk.
Variable mortgages = tied to Bank of Canada, potential savings, lower penalty risk, but less predictable.
VRM vs. ARM = VRM keeps payments steady while ARM adjusts payments with rates.


Next Steps

Choosing between fixed and variable depends on your risk tolerance, financial goals, and comfort with rate changes. If you’re unsure which option is right for you, let’s talk about your situation and find the best fit.

The option to switch from a variable mortgage to a fixed mortgage during your term.
Mortgage Term:
The length of your mortgage contract with your lender (typically 1–5 years), after which you need to renew.
Prime Rate:
The interest rate banks use as a baseline for loans, influenced by the Bank of Canada’s overnight rate.

If you own a property with a mortgage, you've probably heard the terms "renewal" and "refinance" thrown around. While both involve obtaining a new term for your mortgage, there are some important differences to understand. Let's break down what each one means and when you might use them. Understanding Mortgage Basics In Canada, when you take out a mortgage, the payments are typically spread over 25 to 30 years. This period is known as the amortization. However, unlike in the U.S., Canadians do not keep the same interest rate and payment terms for the entire amortization period. Instead, you have an initial term, usually 3 to 5 years, after which you need to renew into a new term. For example, if you have a 25-year mortgage with 5-year terms, you will need to renew your mortgage four times throughout its lifespan. It's also common to have a mix of different term lengths over the course of your mortgage. What is a Mortgage Renewal? A mortgage renewal occurs at the end of your mortgage term. When you renew, you start a new term with a new interest rate while keeping the remaining details of your mortgage the same. The key element here is that the mortgage charge registered on your property's title remains unchanged. A renewal is straightforward and typically does not involve any significant changes to your mortgage agreement other than a new interest rate. Think of it as hitting the "continue" button on your mortgage, but at new rates. What is a Mortgage Refinance? A mortgage refinance is different. When you refinance, you are making changes to your original mortgage agreement. This means paying off your existing mortgage and registering a new one on your property's title. Essentially, you are taking out a completely new mortgage for the same property. People commonly refinance to: Access the equity in their home for investments or major purchases Consolidate high-interest debt into their lower-rate mortgage Extend the amortization period to reduce monthly payments and improve cash flow Make significant changes to their mortgage structure It's important to note that refinancing is not allowed for insured properties (those with less than a 20% down payment at purchase). This means the maximum loan amount in a refinance is 80% of your property value. What About Switching Lenders? If you want to keep everything the same but switch lenders for a better rate, this is known as a transfer. A transfer is a type of renewal where the original mortgage charge is transferred from one lender to another. Depending on the lenders involved, you might be able to make minor changes (like extending the amortization or changing borrowers) without needing a full refinance. Why Timing Matters Your mortgage maturity date is when your current term ends. This is the ideal time to either renew or refinance. If you refinance or switch lenders before the maturity date, you will face a prepayment penalty. If you refinance, renew or transfer at maturity, there is no penalty. Real-World Example A homeowner with a $450,000 mortgage is reaching the end of their 5-year term. Their lender offers a renewal rate, but they also have $40,000 in high-interest credit card debt. Option 1: Renewal They accept the new term. Their mortgage stays the same. Their debt remains separate at high interest rates. Option 2: Refinance at Maturity They consolidate the credit card debt into the new mortgage. Their total monthly payments drop significantly, even after accounting for the new mortgage balance. In this situation, refinancing provides better cash flow and a simpler payment structure. Quick Summary Mortgage Renewal: Starts a new term for your existing mortgage Mortgage charge on your title stays the same Keeps all other terms the same aside from interest rate Can switch lenders at renewal through a transfer No penalty when done at maturity Mortgage Refinance: Pays off current mortgage and creates a new one New mortgage charge registered on your title Often resets the amortization period Can access equity or make structural changes Maximum 80% of property value for uninsured mortgages Incurs penalty if done before maturity Next Steps Understanding the difference between renewal and refinance helps you make informed decisions about managing your mortgage.

Insured Mortgage: A mortgage where the down payment was less than 20%, requiring mortgage default insurance to be added. Maturity Date: The end date of your current mortgage term, when you need to renew or refinance. Mortgage Charge: The legal registration of your mortgage on your property's title. Pre-payment Penalty: A fee charged by your lender if you pay off your mortgage before the end of your term. Refinance: Replacing your existing mortgage with a new mortgage, often with different terms or to access equity. Renewal: Starting a new term for your existing mortgage, typically just updating the interest rate. Term: The length of time your current mortgage contract is in effect, typically 3-5 years in Canada. Transfer: Moving your mortgage from one lender to another at renewal without changing other terms.
