The Mortgage Stress Test:
What It Means for You in Ontario

The bank quotes you a rate

Say they offer you 4.44% on a 5-year fixed mortgage. That's what you'd actually pay.

They add 2% to test you

The bank calculates your payments at 6.44% instead — even though you'll never pay that rate. 6.44% is your "stress test rate".

Your borrowing limit is based on that higher rate

If you can afford payments at 6.44%, you're approved — at your actual rate of 4.44%. This means most people qualify for less than they hoped.

Big banks — RBC, TD, BMO, Scotiabank, CIBC, National Bank

All six big banks must run the stress test on every new mortgage. No exceptions.

Mortgage companies — First National, MCAP, CMLS

These lenders only do mortgages (no chequing accounts), but the same government rules apply to them.

Trust companies — Home Trust, Equitable Bank

Same rules as the big banks. The stress test applies to every new mortgage.

Ontario credit unions — Meridian, Alterna, DUCA

Credit unions are not legally required to run the stress test — but most do anyway. Meridian, Alterna, and DUCA all use similar qualifying rules by choice. Don't assume you can avoid the stress test by switching to a credit union. Where they sometimes help: they can be more flexible about how your income is calculated, especially if you're self-employed or have irregular earnings.

Private lenders

Private lenders look at how much equity you have in your home — not your income or the stress test. The catch: their interest rates are much higher than a bank. Rates vary depending on the lender, the property, and your situation — often somewhere in the 9%–13%+ range for first mortgages, but this can be higher. Best used as a short-term bridge while you sort out your situation, not as a permanent mortgage.

Alternative lenders (sometimes called B-lenders)

This is a middle ground between big banks and private lenders. Some use the stress test, some don't. They're generally more flexible about what counts as income. Rates are higher than a bank but lower than a private lender. A good option if the bank said no due to your income type.

Renewing with your same lender — no extra money borrowed

If you're just renewing your mortgage at the end of your term with the same lender and the same amount, you don't have to pass the stress test again. This has been the rule since June 2021.

Switching lenders at renewal — same amount, same payoff timeline

Since November 2024, you can switch to a different lender at renewal without re-doing the stress test — as long as the mortgage amount and payoff timeline stay the same. This makes shopping around at renewal much easier.

Adding your spouse, partner, or a family member puts both incomes on the application. This is the fastest way to qualify for a larger mortgage — two incomes together often unlock significantly more than one.

Every debt payment you have (car loan, credit card, line of credit) reduces how much mortgage you can get. As a rough illustration: eliminating a $500/month debt payment before applying could meaningfully increase your qualifying amount — the exact figure depends on your income, rate, and how long you take to pay off the mortgage.

First-time buyers and people buying a newly built home can now choose to pay off their mortgage over 30 years. Lower monthly payments mean you can qualify for more — and your day-to-day budget has more breathing room.

The more you put down, the smaller your mortgage — and the easier it is to qualify. Putting down 20% or more also means you avoid paying mortgage insurance (which can cost thousands of dollars).

While most credit unions still run a stress test, they can sometimes be more flexible about how your income is calculated. Alternative lenders are another option if the bank said no — rates are a bit higher, but still much lower than a private lender.

If you're self-employed or earn commissions, bonuses, or rental income, how you document it matters a lot. A broker who understands your income type can often help you qualify for significantly more — legally and accurately.

You work for yourself

Banks look at your last 2 years of tax returns. If you write off a lot of expenses, your reported income may be lower than what you actually earn — which means the bank may qualify you for less than you expected. Some lenders can look at your income more holistically. Worth exploring with a broker.

Your mortgage is coming up for renewal

Staying with the same lender and the same mortgage amount? No stress test. Switching to a different lender at renewal (same amount, same payoff timeline)? Also no stress test since November 2024. Want to borrow more? The stress test applies.

You want to borrow against your home

If you're refinancing to access equity — say, for renovations or to pay off other debts — you'll go through the stress test again. It's worth knowing your qualifying number before you commit to a plan.

You're buying your first home

The same stress test rules apply. Your advantages: you can now spread payments over 30 years instead of 25 (which makes qualifying easier), and the government's First Home Savings Account (FHSA) lets you contribute money, get a tax deduction, and withdraw it tax-free when you buy a qualifying first home. Talk to a broker or financial advisor to make sure you're using it correctly.

Your credit score isn't great

Private lenders can often approve you based on how much equity you have in your home — not your credit score or the stress test. The trade-off is a much higher interest rate (typically 9%–13%+). It works best as a short-term solution while you rebuild your credit.

The bank turned you down

A bank saying no is not a dead end. It means that particular lender's rules didn't work for your situation. A broker can quickly tell you which type of lender makes more sense for you — whether that's an alternative lender, a credit union, or a private mortgage.

Before approving your mortgage, the bank has to check whether you could still afford your payments if interest rates went up by 2%. So if they're offering you a rate of 4.44%, they actually check if you can handle payments at 6.44%. If you pass that higher check, you get the mortgage at the lower rate. The result: at current rate levels, most people qualify for roughly 18–22% less than they would without this rule — though the exact reduction depends on the gap between your rate and the stress test rate.

It's a safety net — for you and for the housing market. If you only barely afford your mortgage at today's rates, a rate increase could mean missed payments or losing your home. The stress test is designed to make sure you have some room to absorb a rate change without everything falling apart.

If you're renewing with the same lender and not borrowing any extra money, no — you don't have to pass the stress test again. And since November 2024, you can also switch to a different lender at renewal (keeping the same amount and payoff timeline) without re-doing the stress test. If you want to borrow more or refinance, the stress test applies.

Almost certainly not. Credit unions technically don't have to follow the government's stress test rule — but most of the major Ontario ones (Meridian, Alterna, DUCA) choose to apply the same qualifying checks anyway. Where credit unions can genuinely help is if your income is complicated — for example if you're self-employed — because they may count your income differently.

The bank adds up your mortgage payment, property taxes, home heating costs, and (if you own a condo) half your condo fees. All of that combined should be no more than 39% of your gross (before-tax) household income. If you're putting less than 20% down and getting mortgage insurance, the limit is slightly higher at 44%.

The bank always uses whichever is higher: your actual rate plus 2%, or 5.25% (the minimum floor set by the government). So even if rates dropped to 2%, you'd still be tested at 5.25%. Right now, with rates around 4.44%, the stress test rate is 6.44%.

No. A bank decline means that lender said no — it doesn't mean you can't get a mortgage. Alternative lenders and some credit unions are more flexible about income types. Private lenders can help if you have equity in a home. A mortgage broker can look at your full picture and tell you which door is most likely to open for you.
