You Probably Don't Need the Stress Test to Switch Lenders Anymore

Here's a rule change that got about ten minutes of coverage and then vanished: since November 2024, most Canadians renewing a mortgage can move to a different lender without passing the stress test.

If you've been assuming you're stuck with whatever your bank mails you — because your income dipped, or you went self-employed, or you just remember how brutal qualifying was the first time — that assumption is probably out of date. It's worth ten minutes to find out.

What actually changed

On 21 November 2024, OSFI dropped the minimum qualifying rate requirement for what the industry calls a straight switch: moving your existing mortgage to a new lender at renewal without increasing the balance or stretching the amortization. Borrowers with insured mortgages — less than 20% down — were already exempt. The November change extended it to uninsured borrowers, which is roughly 70% of the market.

Before that, switching meant requalifying at the greater of your contract rate plus two percent or 5.25%. Staying put meant no requalification at all. That asymmetry did exactly what you'd expect: it handed your existing lender the upper hand at the precise moment you were supposed to be shopping. OSFI's own reasoning for scrapping it was that the risks it was meant to guard against never really showed up.

So the playing field levelled. Mostly.

Two catches worth knowing before you get excited

The exemption isn't an approval. OSFI removed a rate test, not the underwriting. The new lender still pulls your credit, still verifies your income, still assesses whether you can carry the debt. The difference is that they now measure you against your actual contract rate rather than a stress-tested one — which lowers the income bar meaningfully, but doesn't remove it. A file that's genuinely deteriorated is still a file that can be declined.

Some lenders kept the test anyway. This is the part almost nobody mentions. OSFI removed the requirement; it didn't forbid banks from applying their own. BMO adopted the exemption and then reversed itself in December 2024, going back to stress-testing uninsured switches while it worked out its own approach. Others have their own quirks.

Which means the practical answer to "can I switch?" is now lender-specific rather than rule-specific. That's genuinely harder to research on your own, and it's most of the value a licensed mortgage agent adds at renewal — knowing which lenders are actually applying the exemption this month, not which ones announced they would.

What counts as "straight," precisely

Same balance. Same remaining amortization. Move either one and you're outside the exemption.

That trips people up, because the two things borrowers most often want at renewal — a bit of cash out, or a longer amortization to cut the payment — are exactly the two things that convert a switch into a refinance. And a refinance is fully qualified: stress test, 80% loan-to-value ceiling, the works.

It's not a reason to avoid refinancing. It's a reason to know which transaction you're actually asking for before you start, because they have completely different qualification bars.

What it's worth in dollars

Renewal offers tend to arrive a few tenths of a percent above what's available if you shop. That sounds like rounding. It isn't.

On a $400,000 balance with 25 years remaining, half a percentage point is about $112 a month. Over a five-year term that's roughly $9,600 in extra interest — and because more of every payment went to interest, you also arrive at maturity owing about $2,850 more. Call it $12,000 for signing the first thing you were sent.

Our mortgage renewal calculator runs your own numbers against current rates. The gap is usually wider than people guess, which is precisely what the old rules were counting on.

The 120-day window

Most Canadian lenders will hold a rate for 90 to 120 days at no cost. Start four months before maturity and you can lock today's rate while you shop; if rates fall before closing, most lenders will honour the lower one. Start in the final month and you're negotiating against a deadline you can't move, which is not negotiating.

A reasonable sequence: pull your current rate and balance, check what's on offer at today's Ontario rates, then ask your existing lender to match. Plenty will. If they won't, you now have somewhere to go — which you may not have had two years ago.

If a switch still isn't realistic

Some files genuinely won't move. Income that can't be documented yet, credit that's taken real damage, or a debt load that's grown since you last qualified. If that's you, three options — and only one of them is bad.

Renew where you are and negotiate anyway. Less leverage than someone who can walk, but not none. Ask directly, be willing to wait, and use the term to fix whatever is blocking the move.

Go to a B lender. Regulated institutions like Home Trust, Equitable Bank and MCAN work with more flexible credit and income rules, generally from around a 550 score, at roughly 1–2% above bank rates plus a lender fee of about 1% of the mortgage. On $400,000 that fee is about $4,000 — real money, worth it only if the alternative is worse. Here's what B lenders approve and what they charge. If the issue is documenting self-employed income specifically, that's its own conversation and often more solvable than it looks.

Let it drift past maturity. This is the bad one. An unrenewed mortgage doesn't vanish; it typically converts to the lender's open or posted rate, which is worse than anything you'd have negotiated. Doing nothing is the most expensive thing available.

The short version

The rule that made your renewal offer hard to refuse is mostly gone. Not entirely — the lender still underwrites you, some banks still apply a test of their own, and the moment you ask for more money or a longer amortization you're back to full qualification.

But if you're a straight switch and your situation is roughly what it was, you have more room than you think. Find that out at 120 days, and the worst case is your current lender matches a better offer. That's a good worst case.
