There is a common misconception that mortgage loan insurance protects the borrower. This is not the case. Mortgage loan insurance is there to protect the lender against default in payments by the homebuyer. If the buyer has a down payment of less than 20 per cent of the purchase price, the lender will purchase default insurance and pass that cost on to the borrower. This can be paid up front, or tacked on to the mortgage payments and stretched out over time. Mortgage loan insurance is offered by companies like Canada Mortgage and Housing Corp., Genworth Financial Canada, Canada Guaranty, or another approved private insurer.
