Variable-Rate Mortgage Holders: 3 Steps to Prepare for Bank of Canada Rate Increases
Variable-Rate Mortgage Holders: 3 Steps to Prepare for Bank of Canada Rate Increases
The Bank of Canada policy rate sits at 4.25% in September 2026, and borrowers who locked in variables during 2021 at sub-2% are now living with a payment they've seen rise three, four, sometimes five times. If you're still variable, here's how to position yourself before the next cycle.
1. Calculate Your Trigger Rate and Know Your Amortization
Run the numbers on your current amortization, not the original one. Most variable-rate, fixed-payment mortgages (VRMs) have already crossed into negative amortization, meaning your monthly payment no longer covers the interest portion and your principal balance is growing instead of shrinking. The Financial Consumer Agency of Canada calls this the "trigger rate," and most lenders will force a payment increase or require a lump-sum injection once you hit it.
Log into your lender portal and check your remaining amortization. If it's pushed past 30 years or if your statement shows principal increasing month-over-month, you're already there. TD, RBC, and Scotiabank will send a letter when you cross the threshold, but the letter often arrives 60 days late and buried in routine correspondence. Don't wait for it.
The fix: request a new amortization schedule from your lender. If your amortization has ballooned to 35 or 40 years, you need to decide now whether to increase your payment voluntarily, make a lump-sum prepayment, or lock into a fixed rate. Waiting for the bank to force your hand typically means less favourable terms.
2. Use Your Prepayment Privilege Before You Lock In
Most variable contracts allow 10% to 20% of the original principal as a penalty-free prepayment each year. If you have cash sitting in a HISA earning 4%, and your variable rate is Prime + 0.5% (currently around 6.5%), moving that cash onto your mortgage saves you the spread and reduces the principal balance before any rate lock.
This matters more than it sounds. A $400,000 mortgage with a $40,000 prepayment (10% privilege) drops your remaining balance to $360,000. If you then lock into a fixed rate, you're locking a smaller number. On a 5-year fixed at 5.89% (current insured rate as of September 2026 per WOWA.ca), that $40,000 reduction saves roughly $14,000 in interest over the term.
Prepayment privileges reset annually on your mortgage anniversary date, and they don't roll over. If you're close to your anniversary and you haven't used it, this is a use-it-or-lose-it window.
3. Lock Your Rate Only When You've Compared the Full Term Cost
Variable-to-fixed conversions are penalty-free, but the rate you get quoted is rarely the best rate in the market. Lenders know you're motivated, and they price accordingly. Before you accept the lender's offer, pull current fixed rates from at least two brokers and compare the total interest cost over the full term, not just the rate.
Here's the math that matters: if your lender offers you 6.25% on a 5-year fixed and the broker shows you 5.89%, that's 36 basis points. On a $400,000 mortgage, that's $7,200 more in interest over five years. The difference compounds if you're renewing into another term at the end.
The penalty for breaking most variables is three months' interest, typically $6,000 to $8,000 on a $400,000 balance. If switching to a broker-sourced fixed saves you $7,200 and costs you $7,000 in penalty, you're net-positive by year two. Run the numbers with your specific balance and rates before you commit.
Most borrowers lock when the Bank of Canada signals a hike, which is exactly when lenders raise their fixed rates. If you're going to lock, do it before the announcement, not after.
