Good to know

Lenders qualify every buyer at the greater of the contract rate plus 2% or 5.25%, whatever rate they will actually pay.
The 39% and 44% limits are CMHC’s, for insured mortgages. Most lenders use them for uninsured mortgages too; some are stricter.
An insured mortgage also needs a credit score of at least 600 for one of the borrowers.
