Mortgage Default Insurance Explained

Mortgage default insurance (often called CMHC insurance) is a mandatory premium that protects your lender if you default on a mortgage. In Canada, this insurance is required when your down payment is less than 20% of the home's purchase price. It does not protect you, the borrower – it protects the lender against financial loss. This guide explains how mortgage default insurance works, what it costs, and how it affects your overall mortgage.

What Is Mortgage Default Insurance?

Mortgage default insurance is a one-time premium paid by the borrower (usually added to the mortgage principal) that guarantees the lender will recover a portion of the loan if you stop making payments. In Canada, this insurance is provided by three main insurers: the Canada Mortgage and Housing Corporation (CMHC), Sagen, and Canada Guaranty. It applies to conventional mortgages – those with less than a 20% down payment. The insurance does not cover you if you lose your job or face financial hardship; it only covers the lender's loss.

When Is Mortgage Default Insurance Required?

You must purchase mortgage default insurance if your down payment is less than 20% of the home's purchase price. This rule applies to all residential properties with a purchase price up to $1 million (as of general guidance). For homes over $1 million, a minimum 20% down payment is usually required, so insurance is not needed. Certain exceptions exist – for example, if you are self-employed or have a non-traditional income source, some lenders may still require insurance even with a larger down payment. Generally, the insurance is mandatory for high-ratio mortgages (those with a loan-to-value ratio above 80%).

How Much Does Mortgage Default Insurance Cost?

The premium is calculated as a percentage of your mortgage amount and depends on your down payment size. The smaller your down payment, the higher the premium. Premiums are typically added to your mortgage principal, meaning you pay interest on them over the amortization period. Below is an example of typical premium ranges (subject to change by insurers):

For example, if you put 5% down on a $400,000 home, your mortgage would be $380,000. The insurance premium at 4% would be $15,200, added to the mortgage, making the total amount $395,200. You then pay interest on that higher amount over your amortization period. Keep in mind that the premium is a general guide; the actual rate may vary by insurer and your credit score.

How to Avoid Mortgage Default Insurance

The most straightforward way to avoid paying mortgage default insurance is to make a down payment of at least 20% of the purchase price. This gives you a conventional mortgage with no insurance requirement. Other strategies include:

• Buying a less expensive home so that 20% down is more achievable.
• Using a financial gift from a family member to boost your down payment (subject to lender requirements).
• Considering a co-signer with strong income and credit to help you reach the 20% threshold.
• Saving for a longer period before purchasing.

Remember, if you do need mortgage default insurance, it can actually help you qualify for a mortgage sooner and with a lower down payment, which may be worth the added cost.

Impact on Your Monthly Payments and Amortization

Because the insurance premium is added to your mortgage principal, your monthly payments increase slightly. However, insured mortgages often come with lower interest rates from lenders because the insurance reduces the lender's risk. This can partially offset the premium cost over the term. The amortization period (the total time to pay off the mortgage) remains the same – typically 25 years for high-ratio mortgages. If you later refinance your mortgage, you may be able to remove the insurance if your home equity has grown above 20%, but this depends on the lender and the type of refinance. Generally, once a mortgage is insured, the insurance stays for the life of that mortgage, even if you renew with the same lender. Switching lenders at renewal may require a new insurance assessment.

Your credit score plays a role in whether you qualify for a mortgage and the interest rate you receive, but it does not directly affect the insurance premium – that is based solely on your down payment size. Lenders will also check your credit report from Equifax or TransUnion Canada as part of the mortgage approval process.

Understanding mortgage default insurance helps you make informed decisions about your down payment, mortgage term, and overall home-buying budget. As always, this is general educational information and not financial advice. Consult a licensed mortgage professional for guidance tailored to your situation.
