What Is Mortgage Default Insurance in Canada? Complete 2026 Guide

With the Bank of Canada holding its policy rate at 2.25% and renewal volumes easing through 2026, thousands of first-time buyers are finally jumping into the housing market — only to discover an unexpected cost at closing. Mortgage default insurance in Canada is mandatory if you’re putting down less than 20%, and it can add thousands of dollars to your mortgage. If you’ve seen “CMHC insurance” on your mortgage documents and wondered why you’re paying to protect your lender, you’re not alone. In this guide, you’ll learn exactly what mortgage default insurance is, how much it costs, when you can avoid it, and how to minimize what you pay.

Quick Answer:

• Mortgage default insurance protects your lender (not you) if you stop making payments — and it’s required by law when your down payment is under 20%
• The premium ranges from 2.8% to 4.0% of your mortgage amount, depending on your down payment size, and gets added to your mortgage balance
• You cannot avoid this insurance with less than 20% down, but you can reduce the premium by increasing your down payment — even small bumps help
• Since December 2024, first-time buyers (and buyers of new construction) can access 30-year amortizations on insured mortgages, not just the traditional 25-year cap
• This is completely different from mortgage life insurance, which pays off your mortgage if you die

What Is Mortgage Default Insurance in Canada and Why Does It Exist?

Mortgage default insurance is an insurance policy that protects the lender — not the buyer — if the borrower stops paying the mortgage. In Canada, the government requires this insurance whenever a home buyer puts down less than 20% of the purchase price. This type of mortgage is called a “high-ratio mortgage” because the loan-to-value ratio exceeds 80%.

The logic behind this requirement is straightforward. When you put down a small down payment, you’re borrowing a larger percentage of the home’s value. If housing prices drop or you face financial hardship and can’t make payments, the lender faces a bigger potential loss. The insurance guarantees the lender will recover their money even if you default and the home sells for less than what’s owed.

Who Provides Mortgage Default Insurance?

Three organizations provide mortgage default insurance in Canada:

• Canada Mortgage and Housing Corporation (CMHC) — A federal Crown corporation and the largest insurer
• Sagen (formerly Genworth Canada) — A private insurer
• Canada Guaranty — Another private insurer

All three use virtually identical premium rates set by government regulation. Your lender typically chooses which insurer to use, though the cost to you remains the same regardless. When people say “CMHC insurance,” they’re often referring to mortgage default insurance generally, even if a private insurer provides the actual policy.

The Minimum Down Payment Rules

Canada has specific minimum down payment requirements based on purchase price:

• Homes up to $500,000: Minimum 5% down payment
• Homes $500,001 to $1,499,999: 5% on the first $500,000, plus 10% on the portion above $500,000
• Homes $1,500,000 and above: Minimum 20% down payment (no high-ratio mortgage allowed)

This means mortgage default insurance is only available for homes under $1.5 million. If you’re buying a more expensive property, you must have at least 20% down — period.

How Much Does CMHC Insurance Cost in 2026?

The mortgage insurance premium in Canada is calculated as a percentage of your mortgage amount (the loan, not the purchase price). The percentage depends on your loan-to-value (LTV) ratio — essentially, how much you’re borrowing compared to the home’s value.

Here’s the current premium structure for standard high-ratio mortgages:

Notice how the premium drops significantly as your down payment increases. Going from 5% down to 10% down saves you nearly 1% of your mortgage amount — that’s $4,500 on a $500,000 mortgage.

How the Premium Gets Added to Your Mortgage

Here’s something many first-time buyers don’t realize: you don’t pay the insurance premium upfront. Instead, it gets added to your mortgage balance and financed over your entire amortization period.

Let’s say you’re buying a $550,000 home with 10% down ($55,000). Your mortgage would be $495,000. With a 3.10% insurance premium, that’s $15,345 in mortgage default insurance (verified: $495,000 × 3.10%). Your total mortgage balance becomes $510,345.

You’ll pay interest on that insurance premium for the life of your mortgage. At the current lowest 5-year fixed rate of 4.04% (as of August 2026), a $15,345 premium adds approximately $79 per month to your payment when financed over 25 years (independently verified) — money that never builds equity, since it’s paying for the lender’s protection, not yours.

Provincial Sales Tax on Insurance Premiums

If you live in Ontario, Quebec, or Saskatchewan, there’s another cost to consider: provincial sales tax (PST) on the insurance premium. Unlike the premium itself, PST cannot be added to your mortgage — you must pay it at closing.

• Ontario: 8% PST on the premium
• Quebec: 9% PST on the premium
• Saskatchewan: 6% PST on the premium

Using our earlier example of a $15,345 premium, an Ontario buyer would owe $1,228 in PST at closing (verified: $15,345 × 8%). This catches many buyers off guard because it’s a cash expense on top of all other closing costs.

High-Ratio Mortgage Insurance vs. Conventional Mortgages: What’s the Real Difference?

The distinction between high-ratio and conventional mortgages goes beyond just the insurance premium. Here’s a comprehensive comparison:

Here’s an interesting twist: insured mortgages sometimes qualify for slightly lower interest rates. Because the lender faces zero risk of loss (the insurer covers any default), they may offer a rate that’s 0.05% to 0.15% lower than for uninsured mortgages. However, this small rate discount rarely offsets the total cost of the insurance premium plus interest.

💡 The 25-Year Amortization Limit — With an Important Exception

High-ratio mortgages have traditionally been capped at a 25-year amortization period. This changed in December 2024: first-time home buyers (and buyers of newly constructed homes, regardless of first-time buyer status) can now access 30-year amortizations even on insured mortgages. This typically comes with a modest premium surcharge (around 0.20% added to your insurance rate) but can meaningfully lower your monthly payment.

If you’re a repeat buyer without this exception, the traditional 25-year cap still generally applies to insured mortgages. Always ask your lender or broker specifically whether you qualify for the 30-year option — many buyers still assume the 25-year cap is absolute.

How Can You Reduce Your Mortgage Insurance Premium in Canada?

While you can’t negotiate the insurance premium rate, you can take strategic steps to reduce what you pay.

Step 1: Target the Next Premium Tier

Look at the premium tiers and calculate whether you can push your down payment to the next threshold. The biggest jumps in savings happen at 10%, 15%, and 20%.

For a $600,000 home (all figures independently verified):

• 5% down ($30,000): Mortgage = $570,000 × 4.00% = $22,800 premium
• 10% down ($60,000): Mortgage = $540,000 × 3.10% = $16,740 premium
• 15% down ($90,000): Mortgage = $510,000 × 2.80% = $14,280 premium

Saving an extra $30,000 for a 10% down payment instead of 5% saves you approximately $6,060 in insurance costs (verified: $22,800 − $16,740) — and that’s before counting the interest you won’t pay on that amount over your amortization.

Step 2: Use Your FHSA and RRSP Strategically

First-time buyers have powerful tools to boost their down payment. The First Home Savings Account (FHSA) lets you contribute $8,000 per year (up to $40,000 lifetime) and withdraw tax-free for a home purchase. Combined with the Home Buyers’ Plan (HBP), which allows withdrawing up to $60,000 from your RRSP, you could access up to $100,000 tax-advantaged to reach that next down payment tier.

Step 3: Consider a Gifted Down Payment

Family gifts are an acceptable down payment source for insured mortgages. If parents or grandparents can help, even a $20,000 gift might push you from 5% to 10% down, saving thousands in insurance premiums. Just know that lenders require a signed gift letter confirming the money doesn’t need to be repaid.

Step 4: Buy a Less Expensive Home

This sounds obvious, but many buyers stretch to their maximum approval without considering how a lower purchase price affects insurance costs. A smaller mortgage means a lower premium (since the percentage applies to a smaller amount), and potentially further savings if your LTV ratio also improves — plus more manageable monthly payments.

Common Mistakes First-Time Buyers Make with Mortgage Default Insurance

Mistake 1: Forgetting About PST at Closing

Ontario, Quebec, and Saskatchewan buyers often budget carefully for their down payment, legal fees, and land transfer tax — then get blindsided by PST on the insurance premium. On a $600,000 purchase with 10% down, an Ontario buyer owes $1,339 in PST (verified: $16,740 premium × 8%). Budget for this as a cash expense.

Mistake 2: Assuming More Down Payment Always Means Lower Total Cost

If saving for a larger down payment means waiting two more years to buy, run the numbers carefully. In a rising market, home price appreciation might exceed your insurance savings. There’s no universal answer — it depends on your local market, your savings rate, and current interest rates.

With the lowest 3-year fixed rate at 3.94% and 5-year fixed at 4.04% as of August 2026, borrowing costs remain reasonable by recent historical standards. If you’re ready to buy and meet pre-approval requirements, waiting solely to avoid insurance might cost you more than the premium itself.

Mistake 3: Confusing Mortgage Default Insurance with Mortgage Life Insurance

These are completely different products with completely different purposes:

• Mortgage default insurance protects your lender if you stop paying. You pay for it, but it benefits them.
• Mortgage life insurance pays off your mortgage if you die or become critically ill. It protects your family.

Your lender will likely offer mortgage life insurance at signing. That’s a separate decision — and often, a personal term life insurance policy offers better value and more flexibility than bank-offered mortgage life insurance.

Mistake 4: Not Considering Portable Insurance

If you sell your home and buy another, your mortgage default insurance may be portable — meaning you can transfer it to your new property without paying a new premium (assuming your mortgage amount doesn’t increase). Ask your lender about portability terms before assuming you’ll pay insurance twice if you move within a few years.

Does Mortgage Default Insurance Affect Your Interest Rate?

Here’s something that surprises many buyers: insured mortgages often qualify for lower interest rates than uninsured mortgages. Why? Because the lender faces zero default risk — the insurer covers any losses.

This means a buyer putting 15% down (insured) might actually get a better rate than someone putting 20% down (uninsured). The rate difference is typically small (0.05% to 0.15%), but it exists.

That said, the lower rate rarely compensates for the insurance premium cost. On a $500,000 mortgage, a 0.10% rate reduction saves roughly $500 per year in interest. The insurance premium on that same mortgage could be $14,000 to $20,000. The math generally doesn’t favour paying insurance just for the rate benefit.

Some buyers with 20% down actually choose to take out a slightly smaller mortgage that’s insured, then add a second mortgage or line of credit for the remainder — betting that the lower rate on the insured portion will save money overall. This strategy is complex and not suitable for most buyers, especially with current rate uncertainty.

What Happens to Your Insurance When You Renew Your Mortgage?

Good news: mortgage default insurance is a one-time cost. Once you’ve paid the premium (added to your original mortgage), you don’t pay it again at renewal — even if you switch lenders.

Your new lender will verify that your original mortgage was insured and that insurance remains valid. As long as you don’t increase your mortgage amount beyond the original insured balance, you stay covered under the existing policy.

If you need to increase your mortgage at renewal (for renovations or debt consolidation), the additional amount may require new insurance or a “top-up” premium. Rules vary by insurer and lender, so discuss this before assuming your existing insurance covers any increase.

Key Takeaways

• Mortgage default insurance is mandatory in Canada for down payments under 20%, with premiums ranging from 2.8% to 4.0% of your mortgage amount — potentially $14,000 to $20,000+ on a typical purchase
• The premium gets added to your mortgage balance and financed over your full amortization, meaning you pay interest on the insurance for years (verified: $79/month in added interest on a $15,000 premium at 4.04% over 25 years)
• Ontario, Quebec, and Saskatchewan buyers must pay PST on the premium at closing — budget 6% to 9% of your insurance premium as a cash expense
• Since December 2024, first-time buyers (and new construction buyers) can access 30-year amortizations on insured mortgages — not just the traditional 25-year cap
• You can reduce your premium by targeting the next down payment tier (10%, 15%, or 20%), using your FHSA ($8,000/year, $40,000 lifetime) and RRSP HBP ($60,000 maximum) to boost savings
• Mortgage default insurance is completely different from mortgage life insurance — one protects your lender, the other protects your family
• The insurance is a one-time cost that doesn’t repeat at renewal, even if you switch lenders

Frequently Asked Questions

How much does CMHC insurance add to my mortgage payment?

CMHC insurance typically adds $40 to $90 per month to your mortgage payment, depending on your mortgage size and down payment percentage. For example, a $15,000 premium financed over 25 years at 4.04% adds approximately $79 per month (independently verified). The exact amount depends on your amortization period and interest rate, since the premium is rolled into your mortgage principal and accrues interest like the rest of your loan.

Can I avoid paying mortgage default insurance in Canada?

Yes, but only by making a down payment of 20% or more. There is no way to waive, negotiate, or opt out of mortgage default insurance with a smaller down payment — it’s a federal requirement, not a lender policy. If you’re close to 20%, it may be worth waiting to save more or exploring family gift options to reach that threshold and avoid the premium entirely.

Can first-time buyers get a 30-year amortization on an insured mortgage?

Yes. Since December 15, 2024, first-time home buyers (and buyers of newly constructed homes) can access 30-year amortizations even on insured mortgages with less than 20% down — a change from the previous 25-year maximum. This typically adds a small premium surcharge (around 0.20%) to your insurance rate but can meaningfully lower your monthly payment. Repeat buyers without this exception generally remain capped at 25 years for insured mortgages.

Is mortgage default insurance the same as mortgage life insurance?

No, these are completely different products. Mortgage default insurance protects your lender if you stop making payments — you pay for it, but the coverage benefits them. Mortgage life insurance protects your family by paying off your mortgage balance if you die or become critically ill. Your lender will likely offer mortgage life insurance separately; it’s optional and typically more expensive than getting your own term life insurance policy.

Understanding mortgage default insurance in Canada is essential for any first-time buyer putting less than 20% down. While the premium adds significant cost to your mortgage, knowing how the system works lets you make smarter decisions — whether that’s pushing to reach the next down payment tier, budgeting properly for PST at closing, asking about the newer 30-year amortization option, or simply understanding why this cost exists.
