What Is an Insured Mortgage? A Guide for Canadians

You find a home you like. You’ve saved a down payment. The mortgage numbers look manageable.

Then someone tells you that you need mortgage insurance.

Naturally, you might ask a very reasonable question:

“Insured against what?”

And often another one:

“Am I paying insurance to protect myself or the bank?”

Mortgage terminology doesn’t make this particularly intuitive.

An insured mortgage can allow a Canadian homebuyer to purchase a home with less than a 20% down payment, provided the borrower and property meet the applicable requirements. The insurance is mortgage default insurance, and while the borrower generally pays the premium, it protects the mortgage lender if the borrower defaults.

That’s the short version.

What matters when you’re buying a home is what that insurance does to your down payment, mortgage balance, qualification and total cost.

Let’s get into that.

What Is an Insured Mortgage in Canada?

An insured mortgage is a mortgage protected by mortgage default insurance.

In Canada, this commonly comes into play when you’re purchasing a home with a down payment of less than 20%.

Here’s where the name can be misleading.

The insurance isn’t there to cover your mortgage payments if you lose your job or become unable to pay. It protects the lender against losses if the mortgage goes into default.

The homebuyer typically pays the insurance premium.

So yes, you’re paying for insurance that primarily protects the lender.

That sounds a little strange until you look at what it makes possible.

By reducing the lender’s risk, mortgage insurance allows eligible buyers to purchase a home without first saving a full 20% down payment.

For someone trying to get into the housing market, that can make a significant difference.

Why Does Mortgage Default Insurance Exist?

Think about the lender’s position for a moment.

Someone purchasing with a 20% down payment immediately has a meaningful amount of their own money invested in the property.

Someone purchasing with 5% down has much less equity from day one.

That creates additional risk for the lender.

Mortgage default insurance helps cover that risk, which is why eligible borrowers can access mortgage financing with a smaller down payment.

This is also why an insured mortgage isn’t necessarily a “bad” mortgage or something you should automatically avoid.

We’ve seen buyers become so focused on avoiding the insurance premium that they assume waiting until they have 20% down must always be the better financial decision.

Not necessarily.

There are other things to consider, including how long it’ll take to save the additional down payment, what happens to home prices in the meantime, and how much cash you want left after closing.

The insurance premium matters.

It just isn’t the only number that matters.

When Do You Need Mortgage Insurance?

For many owner-occupied home purchases, putting less than 20% down means mortgage default insurance will be required, assuming the mortgage is eligible for insurance.

However, having a down payment of less than 20% is only one part of determining whether a mortgage qualifies for insurance.

There are rules around borrower qualification, property eligibility, purchase price, amortization and other factors, and those rules can change.

That’s an important distinction.

Less than 20% down doesn’t simply mean “pay the premium and you’re approved.”

You still need to qualify for the mortgage.

If you’re planning a purchase close to the limits of your budget or you’re unsure whether the property qualifies, we’d rather check that before you make an offer.

How Much Down Payment Do You Need?

This is where people often hear “5% down” and assume that’s the whole rule.

It’s not quite that simple.

Canada’s minimum down payment requirements are tiered based on the home’s purchase price. Current federal rules allow eligible buyers to put 5% down on the first $500,000 of the purchase price and 10% on the portion above $500,000, for homes priced below $1.5 million. Homes at $1.5 million or more require at least 20% down and aren’t eligible for high-ratio mortgage insurance.

Here’s a simple example.

Suppose you’re buying a home for $700,000.

The minimum down payment would be:

5% of the first $500,000 = $25,000

10% of the remaining $200,000 = $20,000

That gives you a minimum down payment of $45,000.

Because that’s less than 20% of the purchase price, mortgage default insurance would normally be part of the financing if the mortgage otherwise qualifies.

This is exactly why we’d calculate the down payment based on the property you’re actually considering rather than relying on a general percentage you heard somewhere.

Who Provides the Mortgage Insurance?

Canada has mortgage default insurers that work with approved mortgage lenders.

As the homebuyer, you generally aren’t shopping for mortgage default insurance the same way you’d shop for home or auto insurance.

The mortgage lender handles the insurance application as part of the financing process.

From your perspective, the important questions are usually more practical:

Do I qualify?

What’s the premium?

How does it affect my mortgage?

Those are the numbers worth understanding before you commit to the purchase.

Who Actually Pays the Insurance Premium?

This part catches some buyers off guard.

Although the insurance protects the lender, the premium is generally paid by the borrower.

You don’t usually have to write a separate cheque for the full premium at closing.

The premium can typically be added to the mortgage balance, which means you’ll repay it along with the mortgage.

That makes the upfront cost easier to manage, but there’s a trade-off.

If the premium is added to the mortgage, you’re borrowing that money too—and paying mortgage interest on it.

Depending on the province, sales tax on the insurance premium may also apply and may need to be paid separately rather than added to the mortgage.

That’s worth including in your closing-cost budget.

How Much Does Mortgage Default Insurance Cost?

There’s no single flat premium for every insured mortgage.

The cost is generally calculated as a percentage of the mortgage amount, with the percentage affected by the size of your down payment relative to the home’s value.

In simple terms, a smaller down payment generally means a higher insurance premium.

That’s why we’d look at more than whether you can reach the minimum down payment.

Suppose you have additional savings available.

Should all of it go into the down payment?

Would increasing the down payment change the insurance premium enough to make that worthwhile?

Or would keeping some cash available for closing costs, repairs and an emergency fund leave you in a better position?

Those are much better questions than simply asking:

“How do I avoid paying mortgage insurance?”

Sometimes avoiding the premium is the right goal.

Sometimes it isn’t.

Can an Insured Mortgage Get a Lower Interest Rate?

This one seems backwards at first.

You put less money down, yet you may see an insured mortgage advertised at a lower rate than an uninsured mortgage.

How?

Risk.

Because mortgage default insurance protects the lender against certain losses if the borrower defaults, an insured mortgage can represent less credit risk to the lender. That can sometimes result in more favourable mortgage pricing.

It doesn’t mean the insured mortgage is automatically cheaper overall.

You still need to account for the insurance premium.

So, if you’re comparing an insured mortgage with an uninsured one, don’t stop at the interest rate.

Compare the actual financing.

Rate.

Premium.

Mortgage amount.

Monthly payment.

Cash required upfront.

That’s the comparison that tells you something useful.

Insured vs. Uninsured Mortgage: What’s the Real Difference?

The easiest distinction starts with the financing.

An insured mortgage has mortgage default insurance attached to it and must meet the insurer’s eligibility requirements.

An uninsured mortgage doesn’t have that insurance protection.

For many homebuyers, the dividing line is the down payment. Put less than 20% down on an eligible purchase and insurance will generally be required. Put 20% or more down and mortgage default insurance generally isn’t required.

But don’t turn that into:

Insured = bad. Uninsured = good.

That’s far too simplistic.

Imagine one buyer empties nearly every savings account they have just to reach 20% down and avoid the premium.

Another puts less down, accepts the insurance cost and keeps a healthy emergency fund after closing.

Which buyer made the better decision?

You can’t answer that without seeing the rest of their finances.

That’s the point.

Should You Put 20% Down Just to Avoid Mortgage Insurance?

If you comfortably have 20% available, it’s certainly worth comparing.

You’ll avoid the mortgage default insurance premium, borrow less money and start with more equity in your home.

But we’d emphasize the word comfortably.

Buying a home has a habit of producing expenses you didn’t see coming.

Legal costs. Moving. Furniture. Property tax adjustments. A furnace that decides your first winter is the perfect time to retire.

Putting every available dollar into the down payment just to avoid an insurance premium can leave you house-rich and cash-poor.

We’d rather look at the complete financial picture.

How much will you have left after closing?

What will the monthly payment be?

Do you have an emergency fund?

How long would it take you to save 20% if you’re not there yet?

That’s where the decision becomes personal rather than mathematical.

Does an Insured Mortgage Mean You’re Guaranteed Approval?

No.

Mortgage insurance doesn’t replace the mortgage approval process.

Your lender and insurer still need to be comfortable with the application.

Your income matters.

Your debts matter.

Your credit matters.

The property matters.

And you’ll still need to meet the applicable mortgage qualification requirements.

This is one reason a mortgage pre-approval can be useful before you start seriously shopping.

It gives you a chance to look at your down payment, income and borrowing range before there’s a property and an offer deadline involved.

What Happens to the Insurance When You Sell?

This is another area where the word “insurance” can create the wrong expectation.

Mortgage default insurance isn’t like a savings account attached to your house.

If you sell the property, you generally don’t receive the premium back simply because you never defaulted.

Depending on the insurer, lender and transaction, there can be situations where existing mortgage insurance may have portability benefits when moving to another home, subject to the applicable rules.

If you’re moving and already have an insured mortgage, that’s worth checking before automatically starting over.

Frequently Asked Questions

The Bottom Line

So, what is an insured mortgage?

At its simplest, it’s a mortgage backed by default insurance that reduces the lender’s risk and can allow an eligible Canadian homebuyer to purchase with less than 20% down.

But knowing the definition is the easy part.

The more useful question is whether putting less than 20% down makes sense for you.

Sometimes waiting and building a larger down payment is the better move.

Sometimes buying sooner with an insured mortgage leaves you with a healthier cash reserve and gets you into the right home without waiting years to reach 20%.

That’s why we’d rather compare the actual numbers than make a blanket recommendation.

If you’re planning to buy, Red Key Mortgage can help you work through your down payment, estimated mortgage insurance cost, qualification and monthly payments before you start making offers.

Then you can decide based on the full picture—not simply whether the mortgage has the word “insured” attached to it.
