Mortgage Default Insurance Explained

Mortgage Default Insurance in Canada, Explained

If you’re buying with less than 20% down, mortgage default insurance is part of the deal. Here’s what it is, what it costs, and the 2024 rule changes that let more Canadians buy with a smaller down payment — explained by a Calgary mortgage broker.

Quick answer: Mortgage default insurance is mandatory in Canada when your down payment is under 20%. It protects the lender (not you) if you default, and the one-time premium — 0.60% to 4.00% of the loan — is added to your mortgage. Three insurers provide it: CMHC, Sagen and Canada Guaranty. As of December 2024, insured mortgages are available on homes up to $1.5 million (was $1M), and 30-year amortizations are allowed for first-time buyers and buyers of newly built homes.

What is mortgage default insurance?

Mortgage default insurance (often called CMHC insurance) protects your lender from a loss if a borrower stops making payments. It’s mandatory in Canada on any mortgage with a down payment of less than 20% — a “high-ratio” mortgage. It doesn’t protect you or cover your payments; what it does is let lenders say yes to a smaller down payment, which is how most first-time buyers get into the market with as little as 5% down.

Do I need mortgage default insurance?

If your down payment is 20% or more, no — your mortgage is “conventional” and no insurance is required. If it’s under 20%, yes — it’s built into the deal, and the premium is added to your mortgage balance rather than paid up front.

Who qualifies? Eligibility requirements

To have a mortgage insured, borrowers generally need to meet a few criteria:

Credit score: usually a minimum of about 600.

Maximum purchase price: under $1.5 million — raised from $1 million on December 15, 2024.

Minimum down payment: 5% on the first $500,000 of the price, and 10% on the portion between $500,000 and $1.5M (see the table below).

New in 2024: a $1.5M cap and 30-year amortizations

Two federal changes took effect December 15, 2024 and meaningfully expanded who can buy with an insured mortgage:

1

$1.5M price cap

Insured mortgages are now available on homes priced up to $1.5 million — up from the old $1 million limit — so buyers in higher-priced markets can put down less than 20%.

2

30-year amortizations

First-time buyers and anyone buying a newly built home can now choose a 30-year insured amortization (up from 25), which lowers the monthly payment.

3

A small surcharge

Choosing the 30-year amortization adds a 0.20% premium surcharge — a modest cost for the extra breathing room in your monthly budget.

How much does mortgage default insurance cost?

The premium depends on your loan-to-value ratio (LTV) — how much of the home’s value you’re financing. The less you put down, the higher the premium. It’s a one-time cost, added to your mortgage and paid off over time.

Standard premium rates (CMHC, Sagen & Canada Guaranty)
Down paymentLoan-to-valuePremium on loan
35%+ downUp to 65%0.60%
25%–35% down65.01% – 75%1.70%
20%–25% down75.01% – 80%2.40%

10%–15% down85.01% – 90%3.10%
5%–10% down90.01% – 95%4.00%

A 30-year amortization adds a 0.20% surcharge to the rates above. Premiums are non-refundable and are added to your mortgage balance, so you pay interest on them over the life of the loan.

Who provides it? The three insurers

Canada has three mortgage default insurers. Your lender chooses which to use, but they offer similar coverage — and each has niche programs a broker can tap:

  • CMHC — the federal Crown corporation and the original provider.
  • Sagen (formerly Genworth) — programs for new-to-Canada buyers, self-employed, second mortgages, investment properties, and borrowed-down-payment mortgages.
  • Canada Guaranty — programs for new-to-Canada buyers, conventional and rental-property mortgages, second mortgages, and more.

The drawbacks to weigh

Insurance is what makes a low down payment possible, but it isn’t free:

  • Non-refundable — the premium is a real, one-time cost you don’t get back.
  • Interest on the premium — because it’s added to your mortgage, you pay interest on it for the life of the loan.
  • It protects the lender, not you — it’s not homeowner or life insurance.

Sometimes it’s worth putting down a little more to shrink or avoid the premium; sometimes buying sooner with 5% down is the better move. That trade-off is exactly the kind of thing we’ll run the numbers on with you.

Frequently asked questions

Do I have to pay mortgage default insurance?
Only if your down payment is under 20% of the purchase price. At 20% or more, your mortgage is conventional and no insurance is required.
How much does CMHC insurance cost?
The premium is 0.60% to 4.00% of the mortgage, based on your loan-to-value ratio — the less you put down, the higher the premium. With 5% down it’s 4.00%. A 30-year amortization adds a 0.20% surcharge. The premium is added to your mortgage, not paid up front.
What’s the maximum home price for an insured mortgage?
As of December 15, 2024, insured mortgages are available on homes priced under $1.5 million — up from the previous $1 million limit. At $1.5M or more you need 20% down and no insurance is available.
Can I get a 30-year amortization with less than 20% down?
Yes — since December 15, 2024, first-time buyers and buyers of newly built homes can choose a 30-year insured amortization (up from 25 years). It lowers your payment and adds a 0.20% premium surcharge.
Is mortgage default insurance the same as mortgage life insurance?
No. Default insurance protects the lender if you stop paying. Mortgage life or disability insurance protects you and your family. They’re completely different products.
Is the premium refundable if I sell or refinance?
No, the premium is non-refundable. In some cases a portion can be ported to a new home or applied when you increase your loan, which a broker can help you use.
