Should the mortgage stress test be required for renewals?

This post was first published on August 19, 2019, and was updated on November 21, 2024.

Update: As of November 21, 2024, both insured and uninsured mortgage borrowers are exempt from the stress test when switching to a new mortgage lender at renewal time. The new policy applies to all borrowers making "straight switches", meaning their original mortgage amount and amortization period, remains the same.

The below information reflects the state of the mortgage stress test as of August 19, 2019. Changes to the mortgage stress test in early 2020 may affect the relevance of information below.

The Office of the Superintendent of Financial Institutions (OSFI) introduced a mortgage stress test that took effect in January 2018. It requires homebuyers to prove they can afford payments of the greater of the Bank of Canada’s five-year benchmark rate (currently 5.19%) or their contract rate plus two percentage points.

The stress test is meant to ensure first time homebuyers and existing owners can handle interest rate spikes.

Evan Siddall, president and CEO of the Canada Mortgage and Housing Corporation (CMHC), recently argued last year’s mortgage stress test should continue to apply to mortgage renewals.

“In a February 2019 speech, OSFI Assistant Superintendent Carolyn Rogers explained why renewals should not be exempted from the stress test. In brief, OSFI doesn’t want to stimulate competition among banks for weaker credits,” Siddall wrote in a letter to the Standing Committee on Finance in late May.

“We can take the thinking a step further. Lenders often engage in pro-cyclical behaviour such as dumping assets in the face of a crisis, especially weaker assets, sending asset values even lower. We wouldn’t want lenders hiding behind the stress test to justify refusing to renew mortgages,” he continued. “OSFI evidently chose a lesser evil: effectively requiring that existing lenders support their existing customers — a practice they will monitor — in a crisis. Inherently, the policy means that lenders must therefore re-price these exposures instead of refusing to renew.”

The problem with Siddall’s argument is that renewers aren’t “weaker” in terms of credit worthiness than purchasers since they have a history of making mortgage payments over the course of their previous mortgage terms.

And if homeowners attain a lower interest rate by shopping around at renewal, it actually reduces their risk of default.

“If there is a better rate out there and the consumer switches to that lender it, in fact, reduces the risk of a default because the monthly mortgage payments are lower,” James Laird, president of CanWise Financial, said.
