What You Can Expect When Locking in a Variable Rate

Katherine Martin • July 22, 2020

If you have a variable rate mortgage, and recent economic news has you thinking about locking into a fixed rate, here is what you can expect will happen.

Firstly, your lender will be very happy as they will now make considerably more money off you. Not only will your interest rate increase, but the cost of breaking your mortgage will increase as well.

Now, each lender has a different way of handling this process, but it’s very safe to say that regardless of which lender you are with, you will end up paying more money in interest, and potentially way more money if you have to break your mortgage.

Higher Rates

Fixed rates are always higher than variable rates. If you’re a variable rate mortgage holder, this is most likely the reason you went variable in the first place. The perception is that fixed rates are somewhat “safe” while variable rates are “uncertain”. It is true, as the variable rate is tied to prime, it can increase (or decrease) within your term. However, there are controls in place in Canada to ensure that rates don’t take a roller coaster ride. As the Bank of Canada has scheduled rate announcements, 8 times per year, and they rarely move more than 0.25% per move, it’s impossible for your variable rate to double overnight.

Increased Penalty

Obviously each lender has a different way of calculating the cost to break a mortgage, with the Big Banks being absolutely the worst, but a general rule of thumb is that breaking a variable rate mortgage will cost roughly 3 months interest or roughly 0.5% of the total mortgage balance, while breaking a 5 year fixed rate mortgage will roughly cost 4% of the total mortgage balance. So 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.

Reasons People Break Mortgages

Did you know that 6 out of 10 Canadians will break their current mortgage at an average of 38 months? As we’ve discussed, locking in your variable rate to a fixed rate will increase the cost of breaking your mortgage. Despite our best intentions, sometimes life happens, and we need flexibility.

So here is a list of potential reasons you might need to break your mortgage.

  • Sale of your home (you have to move).
  • 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 home)
  • Because you got divorced. (you need to split up your assets and access the equity in your home)
  • Because you (or someone close to you) got sick.
  • Because you lost your job or because you got a new one.
  • Because you got relocated for work.
  • 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 voluntarily paying more interest to the bank, while giving up some of the flexibility to break your mortgage.

Down Payment Options for Canadian Homebuyers

By Katherine Martin • February 25, 2026
For most Canadians, the down payment is the biggest hurdle to homeownership. A down payment is the initial amount you contribute toward your property purchase, while the lender covers the rest through a mortgage. By law, Canadian lenders can only finance up to 95% of a property’s value, which means you’ll need at least 5% down to qualify. If you’re putting down less than 20%, your mortgage must be insured through one of Canada’s three default insurance providers— CMHC, Sagen (formerly Genworth), or Canada Guaranty . This insurance comes at a cost, but it can be rolled into your mortgage amount. The less you put down, the higher the premium. Since saving a down payment can feel overwhelming, it helps to know the different sources you can draw from. Here are the most common options available to Canadian homebuyers: 1. Savings & Personal Resources The most straightforward source is your own savings. Lenders will ask to see a 90-day history of the funds in your account. Any large deposits outside of regular payroll must be explained with documentation—such as the sale of a vehicle or a transfer from an investment account. This requirement isn’t just red tape; it’s part of Canada’s anti-money laundering rules. 2. Proceeds from the Sale of a Property If you’ve recently sold another home, you can use the proceeds as a down payment on your new purchase. Proof of the sale—such as the final statement of adjustments from your lawyer—will be required. 3. RRSP Home Buyers’ Plan (HBP) First-time buyers can withdraw up to $35,000 each (or $70,000 as a couple) from their RRSPs to put toward a down payment under the federal Home Buyers’ Plan . The funds are withdrawn tax-free, but they must be repaid over a 15-year period. This is a popular option for buyers who have been steadily contributing to their retirement savings. 4. Gifted Down Payment With today’s housing prices, many buyers turn to family for help. A parent or immediate family member can provide a gift that makes up part—or even all—of the required down payment. The lender will require a signed gift letter confirming that the money is a true gift (with no repayment expected) and proof that the funds have been deposited into your account. 5. Borrowed Down Payment In some cases, you may be able to borrow your down payment. This option is usually available only if you have strong credit and sufficient income. The payments on the borrowed funds are factored into your debt service ratios, so affordability is key. Lenders typically use 3% of the outstanding balance when calculating the additional payment. The Bottom Line A down payment doesn’t have to come from just one source—it can be a combination of savings, gifted funds, RRSPs, or other resources. What matters most is being able to show where the money came from and that it meets lender requirements. If you’d like to explore your options or learn how much you might qualify for, it’s never too early to start the conversation.

Stress-Testing Your Mortgage Affordability: Why It Matters

By Katherine Martin • February 18, 2026
Buying a home is one of the biggest financial commitments you’ll ever make. That’s why lenders want to be sure you can handle your mortgage payments—not just today, but also if interest rates rise in the future. This is where the mortgage stress test comes in. Many Canadians hear the term but aren’t entirely sure what it means or how it affects them. Let’s break it down in plain language. What Is the Mortgage Stress Test? The stress test is a rule introduced by the federal government that requires all mortgage applicants to qualify at a higher rate than the one they’ll actually pay. Currently, you must qualify at the greater of your contract rate + 2% or the benchmark qualifying rate (set by the Office of the Superintendent of Financial Institutions). For example: If your lender offers you a 5-year fixed mortgage at 5.25%, you must show you could still afford the payments at 7.25% . Even if rates don’t rise that high, the stress test ensures you won’t be overextended if they do. Why Does It Matter? The stress test protects both borrowers and lenders by: Preventing over-borrowing : It ensures you don’t take on more debt than you can realistically handle. Preparing for rate hikes : With interest rates fluctuating, it’s a safeguard against sudden increases. Strengthening financial stability : It lowers the risk of defaults, protecting the housing market as a whole. While it can sometimes feel like a barrier—reducing the amount you qualify for—it’s ultimately designed to keep you from becoming “house poor.” How Does It Impact Buyers? The stress test can significantly affect your homebuying budget. For example, without it, you might qualify for a $600,000 mortgage, but with the stress test applied, you may only qualify for $500,000. That doesn’t mean your dream of homeownership is out of reach—it just means you may need to adjust expectations or explore other strategies, such as: Increasing your down payment Paying down existing debts Considering alternative lenders who may have different qualification standards Why Work With a Mortgage Professional? Every lender applies the stress test, but not every lender views your application the same way. An independent mortgage professional can: Shop multiple lenders to find the best fit Run affordability scenarios at different rates Help you understand how much house you can truly afford—without stretching your finances too thin The Bottom Line The mortgage stress test isn’t meant to stop you from buying a home—it’s there to protect you from financial strain down the road. By understanding how it works and planning ahead, you can make smarter choices and buy with confidence.
