The stress test adds 2% to your contract rate, so a cheaper variable can qualify you for a bigger mortgage than a fixed on the same income. That extra room is real, but after the October 28 rate hike, it’s worth deciding how much of it you actually want to use.

Your pre-approval came back, and the number only works with a variable. The fixed-rate version falls short of the homes you’ve been touring.

Then on October 28, 2026, the Bank of Canada raised its policy rate by 0.25% to 2.50% and said “there could be a need to increase the policy rate further.” Variable rates moved with it.

This isn’t a glitch. The stress test is built so that a cheaper rate qualifies you for more. Here’s what that means for you, and what to do about it.

Why a Variable Rate Can Get You Approved for More

Lenders don’t qualify you at the rate you’ll pay. They qualify you at a higher one, then check that the resulting payment fits your income.

How the stress test treats fixed and variable rates

Your qualifying rate is the greater of 5.25% or your contract rate plus 2%. It applies to insured mortgages and to uninsured mortgages at federally regulated lenders; our B-20 stress test explainer covers the mechanics. Rules can change, so confirm current terms.

Because the buffer sits on top of the contract rate, a variable priced about a point below fixed gets a qualifying rate about a point lower. The same income then supports a bigger loan.

Here’s an illustrative example. A household has $3,500 a month of principal-and-interest room after property tax, heat and debts, at lenders’ debt-service limits. Assume a 25-year amortization and semi-annual compounding.

|   | Fixed (5-year) | Variable | | --- | --- | --- | | Contract rate | 4.99% | 3.90% (prime 4.70% − 0.80%) | | Qualifying rate | 6.99% | 5.90% | | Maximum mortgage | ~$500,000 | ~$552,000 | | Actual payment at maximum | ~$2,906 | ~$2,875 |

On the same income, the variable buyer qualifies for about $52,000 more, with roughly the same starting payment. These rates are hypothetical; check today’s on our rate table.

Why brokers say some buyers have no real choice

It’s common enough that brokers are talking about it. Before the hike, some variable offers were more than a full point below comparable fixed rates, and broker Clinton Wilkins estimated more than 60% of borrowers were taking variable (Canadian Mortgage Trends, Oct 1, 2026).

“Some borrowers will take a variable just because it will be easier to qualify than it would be to qualify for a fixed, as crazy as that might sound,” Wilkins said.

Broker Dave Larock, in the same article, called it a problem with the qualification rules: “It just doesn’t make sense that in uncertain times, the most marginalized borrowers who can barely qualify should have to take variable rate mortgages because that’s the only mortgage they can qualify for.”

If variable is your only approval, you haven’t done anything wrong. But you may have the least room for exactly what just happened.

The Bank of Canada’s Rate Hike Changes the Math

Big-bank prime rose from 4.45% to 4.70%, effective October 29, 2026. The Bank’s next decision is December 9.

What the hike did to variable payments

A variable priced at prime minus 0.80% went from 3.65% to 3.90%. On the $552,000 example, an adjustable-rate payment rises from about $2,801 to about $2,875 a month, roughly $74 more. Each further 0.25% adds about another $75 at this loan size.

With a fixed-payment variable, your payment typically stays the same, but more of it goes to interest and less to principal. You feel the hike in your amortization instead of your chequing account.

How much cushion the stress test really gives you

You were approved at the payment the 5.90% qualifying rate produces: $3,500. Here’s how the same $552,000 loan looks as rates change.

| Variable rate | Monthly payment ($552K, 25-year) | | --- | --- | | 3.90% (today) | ~$2,875 | | +0.25% → 4.15% | ~$2,950 | | +0.50% → 4.40% | ~$3,025 | | +1.00% → 4.90% | ~$3,180 | | Same loan at 4.99% fixed | ~$3,208 | | At the 5.90% qualifying rate | ~$3,500 |

Rates would have to rise about another full point before this variable payment matches what a fixed would cost on the same loan today.

The cushion is real, but it’s sized against your income at approval. It doesn’t cover a job loss, a new baby or a cost-of-living squeeze. That’s where “qualify” and “afford” separate.

As for what’s next, the Bank said more hikes could be needed. As of early October, bond markets were pricing about 1% of hikes over 12 months, and Larock called that pricing “crazy.” We don’t forecast rates, but here’s what moves fixed rates.

Before You Take the Variable: Ways to Qualify for a Fixed

If you’d rather have a fixed, you have levers. Each one comes with a trade-off.

Shop the fixed rate and consider a shorter term

Your qualifying rate tracks your contract rate, so every 0.25% you shave off the fixed rate cuts your qualifying rate by 0.25% too. Fixed rates vary by lender and by whether your mortgage is insured or uninsured, so your first quote may not be the lowest available to you.

A shorter fixed term can help as well. Three-year fixed rates have sometimes priced below five-year this year, and a lower contract rate means a lower qualifying rate. The trade-off is renewing sooner, at whatever rates are on offer then; 91% of borrowers now skip the 5-year fixed, and that article covers the catch.

Down payment, debts and amortization

  • Bigger down payment or lower price. You need a smaller loan. Trade-off: a thinner savings cushion, or a different home.
  • Pay off debts. Clearing a car loan can free up more debt-service room than a rate change. Trade-off: it uses cash you might otherwise keep for emergencies.
  • 30-year amortization, if you’re eligible. Insured first-time buyers and buyers of new builds have had access since December 2024 (eligibility rules can change), and 58.6% of CMHC-insured volume in Q2 2026 used longer amortizations (Canadian Mortgage Trends). In our example, a 30-year fixed qualifies for about $532,000, closing most of the gap. Trade-off: much more interest over the life of the loan. See Should My Mortgage Be 20, 25 or 30 Years?
  • Add a co-borrower. More income on the application raises your limit. Trade-off: they share legal responsibility for the debt.

If Variable Is Your Path, Set It Up to Absorb More Hikes

We’ve covered four ways to make a variable behave more like a fixed. These are the decisions that matter before you sign.

Know which kind of variable you’re signing

With an adjustable-rate mortgage, your payment rises with prime, so you feel this week’s hike right away. With a fixed-payment variable, the payment holds, but if rates climb far enough you can reach your trigger rate, where the payment no longer covers the interest.

Ask your lender which type your offer is. Our variable-rate explainer walks through both.

Locking into a fixed later

Many lenders let you convert a variable to a fixed mid-term, usually at the lender’s fixed rate that day. Rules on which terms you can choose vary.

Before you sign, ask your lender how conversion works and whether it requires requalifying. Keep in mind the fixed rate on conversion day may be higher than today’s.

Budget at your qualifying payment, not your starting payment

If your budget allows, pay as if it were fixed: about $3,208 a month in our example instead of the $2,875 minimum. That’s roughly $333 a month toward principal, building a cushion for future hikes. Check your prepayment privileges first.

Treat $3,500 as your real ceiling. If housing plus the rest of life doesn’t fit at that number, the approval is too big.

Qualifying for It Doesn’t Mean You Should Borrow It

Your approval is the lender’s ceiling, not a target. The right number depends on your job stability, plans and savings.

How much should you actually borrow?

A simple test: could you carry the payment if rates rose 1%? In our example, that’s about $3,180 a month. If that would squeeze you, aim below the approval amount.

A mortgage professional can run this test with your real numbers, including property tax, condo fees and childcare.

You likely won’t be stuck at renewal

Renewing with your current lender typically doesn’t require a new stress test. Since November 21, 2024, an uninsured straight switch to another federally regulated lender (no added funds, no longer amortization) doesn’t either, and insured mortgages can switch under the Canadian Mortgage Charter.

A new lender still reviews your application, and provincially regulated lenders may set their own rules. These rules can change, so verify current terms.

So qualifying with a variable doesn’t typically tie you to your first lender. Our guide to switching lenders at renewal explains how.

Bottom line: variable isn’t a consolation prize; for many borrowers it’s the better-value product. But if it’s the only thing you qualify for, size the loan so the next few hikes are an annoyance, not a crisis.

Your approval shows what a lender will allow. We’ll help you work out what makes sense, and whether a lower fixed rate somewhere else changes the answer. Start your purchase with Homewise, or see today’s fixed and variable rates.

FAQs

Why can I qualify for a variable mortgage but not a fixed one?

The stress test qualifies you at the greater of 5.25% or your contract rate plus 2%. A variable priced below fixed gets a lower qualifying rate, so the same income typically supports a bigger loan.

How much more can I borrow with a variable rate?

It depends on the gap between fixed and variable rates. In our illustrative example, a 3.90% variable qualified for about $552,000 versus about $500,000 at a 4.99% fixed, on the same $3,500 monthly budget.

What mortgage amount or property type (insured or uninsured) qualifies for the lowest variable rates?

Pricing varies by lender and often by whether your mortgage is insured or uninsured. Speaking with a mortgage professional is the best way to see which tier your purchase falls into.

Can I switch my variable mortgage to a fixed rate later?

Many lenders allow it mid-term, usually at their fixed rate that day. Ask your lender how conversion works and whether it requires requalifying before you sign.

Will I have to pass the stress test again at renewal?

Typically not if you renew with your current lender, or since November 21, 2024, for an uninsured straight switch to another federally regulated lender. Insured mortgages can switch under the Canadian Mortgage Charter, but a new lender still reviews your application, so verify current rules before you move.
