B-lenders, credit unions and private lenders: who skips the stress test

Do B-lenders have to use the stress test?

Many do. A number of the lenders called B-lenders are federally regulated banks and trust companies, and OSFI's Guideline B-20 applies to "all federally-regulated financial institutions". OSFI's own list of who it regulates includes Equitable Bank and Equitable Trust, Home Trust Company and Home Bank, Haventree Bank, Peoples Trust Company, Community Trust Company, Concentra Bank and B2B Bank.

So an uninsured mortgage at one of them is tested at the greater of your rate + 2 points or 5.25%, the same as at a big bank. An insured mortgage is tested at any lender, because that rule lives in the federal insurance regulations.

What can a B-lender do differently?

The qualifying rate doesn't flex, but a lot around it does. B-20 tells each lender to "establish debt serviceability metrics (including the method to calculate these metrics)". It sets no number for uninsured loans, only that ratios be calculated conservatively and that a lender's average GDS and TDS sit below its own stated maximums. That leaves room for a federally regulated B-lender to:

• accept higher GDS/TDS ratios than a big bank on uninsured loans;
• use different ways to document income, which matters if you're self-employed or your income is new;
• lend to borrowers with bruised credit, typically at a higher rate and with fees.

None of this is guaranteed, and it varies by lender and by file. The trade-off is cost: you pay more to be approved on terms a bank wouldn't offer. Note what's missing from that list: a lower qualifying rate. If the payment at the qualifying rate is the problem, a federally regulated B-lender has the same rule as the bank.

Are credit unions an alternative?

Sometimes. Credit unions and caisses are regulated by their province, so B-20 doesn't bind their uninsured lending. Some provinces prescribe the same test; others leave the buffer to each credit union:

A credit union in a principles-based province may qualify you with a smaller buffer, but ask it directly: there's no published rate to check, and insured loans are tested at the federal rate regardless. Alberta, where this page's example household lives, is a special case: the last credit-union guidance we found (2018) used contract + 2 points or the Bank of Canada's 5-year posted rate, which at 6.19% on October 28, 2026 is above the 5.25% floor. For this household at 4.58%, that would mean being tested at 6.58%, exactly what B-20 asks. Whether that guidance is still current is unconfirmed.

Do private lenders and MICs use the stress test?

Not under B-20. Private lenders, mortgage investment corporations (MICs) and provincially incorporated trust or loan companies aren't federally regulated, so OSFI's guideline doesn't reach them. OSFI doesn't name them; that's our reading of B-20's scope. Lenders that aren't federally regulated "may also ask you to pass a stress test", as the Financial Consumer Agency of Canada puts it, so ask how a private lender qualifies you.

B-20 does close one door: a federally regulated lender can't team up with another lender in any form that circumvents its loan-to-value limits. So a bank can't arrange a second mortgage with another lender to get you past its own limit.

How much more can you borrow without the test, and what does it cost?

Lenders that skip the buffer usually charge more for the privilege. The question is whether the extra room survives the higher rate. Take one Edmonton household and compare a lender that applies B-20 with one that qualifies at a contract rate 2 points higher.

What happens when you try to move back to a bank?

This is the cost that doesn't show up on day one. Say the household takes the biggest approval on offer, $585,300 at a lender that qualifies at 4.58% with no buffer. Five years later, with the same income, the same property tax and the same rate on offer, it wants to move to a bank.

That move is new lending at the bank. OSFI's straight-switch exemption covers switches between federally regulated lenders, and Finance Canada's summary describes it that way, so expect a mortgage coming from a credit union or private lender to be tested again, and ask the bank. On the $391,473 still owing, with 20 years left, the bank would test the household at 6.58%: GDS 44.4% and TDS 47.5%. It would fail, and would need about $109,300 of income to pass, $13,300 more than today.

A federally regulated B-lender is different. Renewing with it later isn't retested, and an uninsured straight switch from it to another federally regulated lender is exempt, as long as the balance and amortization don't change. That's a real advantage over a private lender or MIC, worth weighing alongside the rate.

When is a B-lender or private loan a bridge, not a fix?

It's a bridge when the reason a bank said no is temporary and you can name the date it ends: a longer record of self-employed income on your tax returns, a collection paid and aged off, a car loan finished. Then a higher-cost term buys time, and you move to a cheaper lender when it's up.

It isn't a fix when the problem is that the payment is too big for your income. A higher rate makes that worse, and the exit test above shows why. If you'd fail the federal test today, check the levers first: how to pass the stress test works through each one, and the stress test calculator solves the co-signer income, down payment or debt payoff that would get you there.

Before signing, get every rate, fee and penalty in writing, and write down your exit: the lender you'd move to, what has to change by then, and the date.
