Buying a home with less than 20 percent down usually means dealing with two very different insurance products at the same time, and it is easy to mix them up. Comparing mortgage default insurance vs home insurance matters because they protect two different interests: one is designed to protect the lender if a mortgage goes unpaid, and the other is arranged by the homeowner to help protect the house and its contents.
Both often show up in the same stack of closing paperwork, which is part of why buyers confuse them. This article explains what each one is, how they typically work, and where the two intersect during a home purchase, a renewal, or a refinance.
What is the difference between mortgage default insurance and home insurance?
Mortgage default insurance is a policy a lender requires on certain mortgages, and it is designed to protect the lender, not the borrower, if the loan goes into default. Home insurance, by contrast, is a policy the homeowner arranges directly with an insurer or broker to help protect the physical property and personal belongings against damage, loss, and liability.
According to the Canada Mortgage and Housing Corporation, mortgage default insurance becomes mandatory whenever a buyer's down payment is below 20 percent of the purchase price. Home insurance is not tied to that same threshold. A lender will still generally expect proof of home insurance before funding any mortgage, high-ratio or conventional, because the home itself is the collateral for the loan.
How mortgage default insurance works
Mortgage default insurance is sold by three providers in Canada: CMHC, a federal Crown corporation, and two private insurers, Sagen and Canada Guaranty. A buyer does not choose which of the three insures their mortgage; the lender makes that decision as part of approving the loan.
The premium is calculated as a percentage of the mortgage amount and generally rises as the down payment shrinks. According to mortgage industry data reported by WOWA (2026), standard premiums have ranged from roughly 2.8 percent of the loan for a 15 to 20 percent down payment up to about 4 percent for a 5 to 10 percent down payment. Rather than being billed separately, the premium is typically added to the mortgage principal and repaid gradually as part of the regular mortgage payments.
Mortgage default insurance is also subject to a property price limit, reported as $1,500,000 following a threshold change that took effect in recent years. Homes priced above that limit generally require a down payment of 20 percent or more and cannot be insured this way, regardless of the buyer's financial profile.
If a homeowner later stops making mortgage payments, the insurer pays the lender for the resulting loss. That payout does not clear the borrower's debt: the insurer can still pursue the homeowner for any shortfall between what was owed and what the home sold for. This is a structural feature of how the product is designed, not a description of what happens in every individual default, and specific outcomes depend on the mortgage documents and the lender involved.
What home insurance is designed to cover instead
Home insurance in Canada is a separate policy that a homeowner chooses and pays for directly, typically on an annual or monthly basis rather than folded into the mortgage. It is generally designed to help protect the dwelling structure, personal belongings inside it, and the homeowner against certain liability claims, alongside additional living expenses if the home becomes temporarily uninhabitable.
Because coverage varies by insurer and by the specific policy wording, only the terms of an actual policy and a licensed broker can confirm what applies to a given home. A lender is often listed on a home insurance policy through a mortgagee or loss payee clause, which is meant to keep the lender informed if coverage lapses, but that clause does not change who the policy actually protects or who chooses it.
Before a mortgage closes, most lenders ask for proof of home insurance, sometimes called a home insurance binder, confirming that a policy will be active on the closing date. That step is separate from, and in addition to, any mortgage default insurance already built into the loan.
Mortgage default insurance vs. home insurance at a glance
The table below summarizes what each product is generally designed to do. Coverage details and requirements vary by lender, insurer, and policy, so only the actual documents and a licensed broker can confirm what applies to a specific mortgage or home.
| Mortgage default insurance | Home insurance | |
|---|---|---|
| Who it is designed to protect | The lender | The homeowner and household |
| Who typically arranges it | The lender, added to the mortgage | The homeowner, through a broker or insurer |
| When it usually applies | Down payment below 20 percent | Almost always required by the lender before closing |
| How it is usually paid | Added to the mortgage principal | Billed directly, usually annually |
| What can trigger it | Missed mortgage payments and default | Damage, loss, or liability events named in the policy |
Benefits of understanding the difference
Knowing which product does what helps a buyer budget more accurately, since mortgage default insurance is folded into the loan while home insurance premiums are a separate, ongoing cost that renews every year. It also clarifies who to contact with a question: a mortgage default insurance question generally goes to the lender or mortgage professional, while a home insurance question belongs with a licensed broker.
This distinction also helps explain the paperwork that shows up at closing. A buyer who understands that one document protects the lender and the other protects their own property is less likely to assume the two overlap or that one makes the other unnecessary.
Where you'll come across this distinction
This comparison tends to surface most often when arranging a mortgage with a smaller down payment, at closing when a lawyer or notary confirms proof of home insurance is in place, and again at mortgage renewal or refinance if the loan-to-value ratio changes. It can also come up on an annual mortgage statement, where a default insurance premium line item sometimes appears alongside principal and interest, separate from any home insurance renewal notice arriving from the homeowner's own insurer or broker.
Homeowners comparing quotes for home insurance in Canada often run into mortgage default insurance terminology at the same time, simply because both processes happen close together during a purchase.
Talk to a licensed broker about your home insurance
A mortgage lender can explain the default insurance built into a loan, but questions about what a specific home insurance policy is designed to include, and how it fits a particular property, belong with a licensed broker.

Coverage details vary by insurer and by policy, and only the wording of an actual policy and a licensed broker can confirm what applies to a specific situation.
