How Mortgage Default Insurance Works

Mortgage default insurance is mandatory if you're buying a home in Canada with a down payment of less than 20% from a federally regulated lender. And the sticker shock can be huge. So let's dig in for some fast facts about what that means.

What is Mortgage Default Insurance?

Mortgage default insurance protects your lender in case you ever default on your mortgage. “Default" means you haven't lived up to your end of the deal you made when you signed on the dotted line for a mortgage.

If you were late with a payment, or you didn't pay the full amount required by the payment due date, you'd be in default. That's the most common type of default, but you can also default if you don't comply with your other obligations under your mortgage contract.

How Does Mortgage Default Insurance Work?

Let's say you continue to miss making payments. Your lender may take action to ensure they get back the money you borrowed from them. That could include forcing the sale of your home and the lender would use the sale proceeds to pay down your mortgage debt to them.

If your mortgage loan has mortgage default insurance and the sale yields less money than what you owe the lender, the difference would be covered by the mortgage default insurance benefit. For example, let's say you have a mortgage of $400,000 and you default on the loan. If the house was sold in a bad real estate market and was only sold for $350,000, then you'd still owe the lender $50,000. The mortgage default insurance would pay the lender that $50,000.

The kicker: the mortgage default insurer may still go after you for that amount. If you find yourself in this position or approaching it, consider speaking with a Licensed Insolvency Trustee.

Another thing to note: “mortgage default insurance" is often referred to as “CMHC insurance" since CMHC (Canadian Mortgage and Housing Corporation) is the biggest provider of this insurance. The other two mortgage default insurance providers in Canada are Genworth Financial and Canada Guaranty.

How Much Does Mortgage Default Insurance Cost?

Like most insurance policies, there's a premium. “Premium" is just insurance-speak for “cost." That cost can be many thousands of dollars. For example, if you were buying a $500,000 home with only a 5% down payment ($25,000), your mortgage default insurance premium would be $19,000. That's calculated by multiplying the "rate" of the insurance by the amount being borrowed. The rate is set by the mortgage default insurers and depends on how large your down payment is, relative to the price of the home. For down payments of 5%, the rate of the current insurance premium is 4%. So we multiply 4% by the amount being borrowed ($475,000) to get $19,000.

That's a lot of money, and most people don't pay for that out of pocket. Instead, they add it to their mortgage. So instead of owing $475,000 on their mortgage for a $500,000 home, they start by owing $494,000.

There's an Incentive to Increase Your Down Payment Size

The higher your down payment, the lower your mortgage default insurance premium will be, and for two reasons.

First, if you reduce the amount you're borrowing, your premium goes down, since the rate is multiplied against a smaller amount.

Second, the rate applied is tiered, meaning that at certain thresholds, the rate decreases. So for that same $500,000 home, if you were to put down a 10% down payment ($50,000), your mortgage loan default insurance drops to $13,950 because the rate charged for the insurance drops from 4% to 3.1%, and you have a lower amount that the rate is applied to.
