Canada's top banking regulator has published the final version of its new mortgage rules, which include a requirement to "stress test" borrowers with uninsured loans to ensure they could withstand higher interest rates.
The Office of the Superintendent of Financial Institutions (OSFI) released new guidelines for the mortgage industry on Tuesday. The regulator floated a similar version of these rules earlier this summer in draft form, but Tuesday's release makes them official as of Jan. 1.
Among the major new rules is a requirement to stress test uninsured borrowers. Previously, only insured borrowers had to undergo such a test.
By law, borrowers with a down payment of under 20 per cent for a home must purchase mortgage insurance. Borrowers pay an insurance premium, but the beneficiary is actually the lender, because the insurance protects the loan giver in the event the borrower defaults on the loan.
The stress test is designed to simulate a borrower's financial situation by assuming they would have to pay back the loan at the posted average — not whatever deal they were able to negotiate. So under OSFI's new rules, borrowers would be stress tested at either the five-year average posted rate, or two per cent higher than their actual mortgage rate — whichever one is higher.
Notably, the new stress test rules won't apply to mortgage renewals as long as they are with the borrower's existing lender.
The regulator published a draft of its new rules over the summer, before consulting with stakeholders about any changes that need to be made. The regulator said it received more than 200 submissions from people in the industry and members of the public about the rules as they were proposed in July.
