Going From A Variable Rate To A Fixed Rate Mortgage

Kambi Heywood • August 14, 2025

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.

One of the major qualifiers lenders look at when considering your application for mortgage financing is your debt service ratios. Now, before we get started, if you prefer to have someone walk through these calculations with you, assess your financial situation, and let you know exactly where you stand, let’s connect. There is no use in dusting off the calculator and running the numbers yourself when we can do it for you! However, if you’re someone who likes to know the nitty-gritty of how things work instead of simply accepting that's just the way it is, this article is for you. But be warned, there are a lot of mortgage words and some math ahead; with that out of the way, let’s get started! “Debt servicing” is the measure of your ability to meet all of your financial obligations. There are two ratios that lenders examine to determine whether you can debt service a mortgage. The first is called the “gross debt service” ratio, or GDS, which is the percentage of your monthly household income that covers your housing costs. The second is called the “total debt service” ratio, or TDS, which is the percentage of your monthly household income covering your housing costs and all your other debts. GDS is your income compared to the cost of financing the mortgage, including your proposed mortgage payments (principal and interest), property taxes, and heat (PITH), plus a percentage of your condo fees (if applicable). Here’s how to calculate your GDS. Principal + Interest + Taxes + Heat / Gross Annual Income Your TDS is your income compared to your GDS plus the payments made to service any existing debts. Debts include car loans, line of credit, credit card payments, support payments, student loans, and anywhere else you’re contractually obligated to make payments. Here’s how to calculate your TDS. Principal + Interest + Taxes + Heat + Other Debts / Gross Annual Income With the calculations for those ratios in place, the next step is to understand that each lender has guidelines that outline a maximum GDS/TDS. Exceeding these guidelines will result in your mortgage application being declined, so the lower your GDS/TDS, the better. If you don’t have any outstanding debts, your GDS and TDS will be the same number. This is a good thing! The maximum ratios vary for conventional mortgage financing based on the lender and mortgage product being offered. However, if your mortgage is high ratio and mortgage default insurance is required, the maximum GDS is 39% with a maximum TDS of 44%. So how does this play out in real life? Well, let’s say you’re currently looking to purchase a property with a payment of $1700/mth (PITH), and your total annual household income is $90,000 ($7500/mth). The calculations would be $1700 divided by $7500, which equals 0.227, giving you a gross debt service ratio of 22.7%. A point of clarity here. When calculating the principal and interest portion of the payment, the Government of Canada has instituted a stress test. It requires you to qualify using the government's qualifying rate (which is higher), not the actual contract rate. This is true for both fixed and variable rate mortgages. Now let’s continue with the scenario. Let’s say that in addition to the payments required to service the property, you have a car payment of $300/mth, child support payments of $500/mth, and between your credit cards and line of credit, you’re responsible for another $700/mth. In total, you pay $1500/mth. So when you add in the $1700/mth PITH, you arrive at a total of $3200/mth for all of your financial obligations. $3200 divided by $7500 equals 0.427, giving you a total debt service ratio of 42.7%. Here’s where it gets interesting. Based on your GDS alone, you can easily afford the property. But when you factor in all your other expenses, the TDS exceeds the allowable limit of 42% (for an insured mortgage anyway). So why does this matter? Well, as it stands, you wouldn’t qualify for the mortgage, even though you are likely paying more than $1700/mth in rent. So then, to qualify, it might be as simple as shuffling some of your debt to lower payments. Or maybe you have 10% of the purchase price saved for a downpayment, changing the mortgage structure to 5% down and using the additional 5% to pay out a portion of your debt might be the difference you need to bring it all together. Here’s the thing, as your actual financial situation is most likely different than the one above, working with an independent mortgage professional is the best way to give yourself options. Don’t do this alone. Your best plan is to seek and rely on the advice provided by an experienced independent mortgage professional. While you might secure a handful of mortgages over your lifetime, we do this every day with people just like you. It’s never too early to start the conversation about mortgage qualification. Going over your application and assessing your debt service ratios in detail beforehand gives you the time needed to make the financial moves necessary to put yourself in the best financial position. So if you find yourself questioning what you can afford or if you want to discuss your GDS/TDS ratios to understand the mortgage process a little better, please get in touch. It would be a pleasure to work with you, we can get a preapproval started right away.

Thinking About Selling Your Home? Start With These 3 Key Questions Selling your home is a major move—emotionally, financially, and logistically. Whether you're upsizing, downsizing, relocating, or just ready for a change, there are a few essential questions you should have answers to before you list that "For Sale" sign. 1. How Will I Get My Home Sale-Ready? Before your property hits the market, you’ll want to make sure it puts its best foot forward. That starts with understanding its current market value—and ends with a plan to maximize its appeal. A real estate professional can walk you through what similar homes in your area have sold for and help tailor a prep plan that aligns with current market conditions. Here are some things you might want to consider: Decluttering and removing personal items Minor touch-ups or repairs Fresh paint inside (and maybe outside too) Updated lighting or fixtures Professional staging Landscaping or exterior cleanup High-quality photos and possibly a virtual tour These aren’t must-dos, but smart investments here can often translate to a higher sale price and faster sale. 2. What Will It Actually Cost to Sell? It’s easy to look at the selling price and subtract your mortgage balance—but the real math is more nuanced. Here's a breakdown of the typical costs involved in selling a home: Real estate agent commissions (plus GST/HST) Legal fees Mortgage discharge fees (and possibly a penalty) Utility and property tax adjustments Moving expenses and/or storage costs That mortgage penalty can be especially tricky—it can sometimes be thousands of dollars, depending on your lender and how much time is left in your term. Not sure what it might cost you? I can help you estimate it. 3. What’s My Plan After the Sale? Knowing your next step is just as important as selling your current home. If you're buying again, don’t assume you’ll automatically qualify for a new mortgage just because you’ve had one before. Lending rules change, and so might your financial situation. Before you sell, talk to a mortgage professional to find out what you’re pre-approved for and what options are available. If you're planning to rent or relocate temporarily, think about timelines, storage, and transition costs. Clarity and preparation go a long way. The best way to reduce stress and make confident decisions is to work with professionals you trust—and ask all the questions you need. If you’re thinking about selling and want help mapping out your next steps, I’d be happy to chat anytime. Let’s make a smart plan, together.
