Locking in a Variable Rate Mortgage

Sabeena Bubber • March 13, 2024

If you have a variable rate mortgage and recent economic news has you thinking about locking into a fixed rate, here’s what you can expect will happen. You can expect to pay a higher interest rate over the remainder of your term, while you could end up paying a significantly higher mortgage penalty should you need to break your mortgage before the end of your term.


Now, each lender has a slightly different way that they handle the process of switching from a variable rate to a fixed rate. Still, it’s safe to say that regardless of which lender you’re with, you’ll end up paying more money in interest and potentially way more money down the line in mortgage penalties should you have to break your mortgage.


Interest rates on fixed rate mortgages


Fixed rate mortgages come with a higher interest rate than variable rate mortgages. If you’re a variable rate mortgage holder, this is one of the reasons you went variable in the first place; to secure the lower rate.


The perception is that fixed rates are somewhat “safe” while variable rates are “uncertain.” And while it’s true that because the variable rate is tied to prime, it can increase (or decrease) within your term, there are controls in place to ensure that rates don’t take a roller coaster ride. The Bank of Canada has eight prescheduled rate announcements per year, where they rarely move more than 0.25% per announcement, making it impossible for your variable rate to double overnight.


Penalties on fixed rate mortgages


Each lender has a different way of calculating the cost to break a mortgage. However, generally speaking, breaking a variable rate mortgage will cost roughly three months of interest or approximately 0.5% of the total mortgage balance. While breaking a fixed rate mortgage could cost upwards of 4% of the total mortgage balance should you need to break it early and you’re required to pay an interest rate differential penalty.


For example, on a $500k mortgage balance, the cost to break your variable rate would be roughly $2500, while the cost to break your fixed rate mortgage could be as high as $20,000, eight times more depending on the lender and how they calculate their interest rate differential penalty.


The flexibility of a variable rate mortgage vs the cost of breaking a fixed rate mortgage is likely another reason you went with a variable rate in the first place.


Breaking your mortgage contract


Did you know that almost 60% of Canadians will break their current mortgage at an average of 38 months? And while you might have the best intention of staying with your existing mortgage for the remainder of your term, sometimes life happens, you need to make a change.


Here’s is a list of potential reasons you might need to break your mortgage before the end of the term. Certainly worth reviewing before committing to a fixed rate mortgage. 


  • Sale of your property because of a job relocation.
  • Purchase of a new home.
  • Access equity from your home.
  • Refinance your home to pay off consumer debt.
  • Refinance your home to fund a new business.
  • Because you got married, you combine assets and want to live together in a new property.
  • Because you got divorced, you need to split up your assets and access the equity in your property
  • Because you or someone close to you got sick
  • Because you lost your job or because you got a new one
  • You want to remove someone from the title.
  • You want to pay off your mortgage before the maturity date.


Essentially, locking your variable rate mortgage into a fixed rate is choosing to voluntarily pay more interest to the lender while giving up some of the flexibility should you need to break your mortgage.

What Mortgage Lenders Need to Know About Your Down Payment Source

By Sabeena Bubber • September 16, 2026
Why the Source of Your Down Payment Matters More Than You Think When buying a home, most people focus on how much they need for a down payment. What often gets overlooked is that where the down payment comes from matters just as much to the lender . The source of your down payment affects approval, risk assessment, and how your mortgage is structured. Here’s why lenders care—and what you need to know. 1. Anti–Money Laundering Requirements Lenders aren’t just being cautious—they’re legally required to verify the source of your down payment. To comply with anti–money laundering regulations, lenders must document where every dollar of the down payment came from on every purchase. Acceptable Down Payment Sources Down payments can come from: Your own savings or investments Borrowed funds through an insured program (such as FlexDown) A gift from an immediate family member How You Prove the Source Personal savings: You’ll need bank statements showing the funds have been in your account for at least 90 days , or proof they were accumulated through payroll deposits or other acceptable sources. Borrowed funds: Any borrowed portion must be included in your debt service ratios , since you’re responsible for repayment. Gifted funds: A signed gift letter is required confirming the money is a true gift with no repayment obligation , along with proof the funds were deposited into your account. 2. Financial Suitability and Risk The source of your down payment also tells the lender a lot about your financial habits. Down payments coming from your own savings demonstrate: Positive cash flow The ability to save consistently Strong financial management This reassures lenders that you’re more likely to keep up with mortgage payments. If the down payment is borrowed or gifted, lenders may look more closely at the rest of your application to ensure the mortgage remains affordable. Why a Larger Down Payment Helps From a lender’s perspective, more equity equals lower risk. The more money you have invested in the property, the less likely you are to walk away from the mortgage. This reduces the lender’s exposure and can sometimes result in better terms. 3. Down Payment and Loan-to-Value (LTV) Your down payment directly establishes your loan-to-value ratio (LTV)—the percentage of the property’s value being financed. In Canada: Lenders can finance up to 95% of a property’s value The buyer must contribute at least 5% as a down payment Example: On a $400,000 purchase: Maximum mortgage = $380,000 Minimum down payment = $20,000 How the Source Affects LTV Property value must be genuine and independently supported. Lenders rely on appraisals and comparable sales—not artificial price inflation. If: The seller provides money back The buyer doesn’t bring the full down payment independently Funds move “behind the scenes” …the lender considers this a change to the LTV and may decline the mortgage. All financial details of the purchase must be fully disclosed. Non-disclosure is mortgage fraud , and lenders will not proceed if the numbers don’t align. Final Thoughts Lenders ask for detailed documentation about your down payment source for good reason—it affects legality, risk, and the structure of your mortgage. Understanding these rules upfront helps avoid delays, declined applications, and last-minute surprises.
