From a recent CBC article.
The bar at which the finances of Canadian mortgage borrowers gets tested has been lowered again, making it easier for would-be homebuyers to reach. In 2017, a stress test was designed during a hot real estate market, to ensure borrowers would be able to pay back their loans if rates rose suddenly. However, the pandemic and historically low-interest rates that are showing no hint at rising have resulted in changes that are making it a little easier for borrowers.
