What Is CMHC Insurance in Canada?
CMHC mortgage insurance protects lenders when your down payment is under 20%. Learn exactly how it works, premium rates for 2026, how to avoid it, and how Canadian mortgage insurance compares to PMI in the US, the UK, and Australia.
TL;DR: CMHC mortgage insurance is a mandatory one-time premium on Canadian mortgages with less than 20% down. It protects the lender (not you), costs 2.80–4.00% of the mortgage depending on your down payment size, and is added to your loan balance. The premium can be partially refunded if you pay down to 75% LTV within 3 years.
If you are buying a home in Canada with less than 20% down, you have heard the term CMHC come up. Maybe your lender mentioned it as a line item on your closing costs. Maybe you saw the premium added to your mortgage balance in the fine print. Either way, what is CMHC insurance is the first question every Canadian buyer with a smaller down payment needs answered.
CMHC mortgage insurance explained simply: it is a one-time premium that protects the lender if you stop making payments. It does not protect you, it protects the bank. But it exists for a good reason: without it, lenders would not offer mortgages with less than 20% down at competitive rates, and millions of Canadians would be locked out of homeownership.
This guide covers what CMHC is, exactly what it costs at different down payment levels, how it compares to Sagen and Canada Guaranty, how the stress test interacts with insured mortgages, and what equivalent products exist in the US, the UK, and Australia.
What Is CMHC Insurance? The Basics
What is CMHC in Canada, CMHC stands for Canada Mortgage and Housing Corporation, a federal Crown corporation. Mortgage default insurance Canada is the technical name for what CMHC offers, along with two private competitors: Sagen and Canada Guaranty.
CMHC insurance how it works is straightforward: you pay a premium calculated as a percentage of your mortgage amount. That premium is added to your loan balance. You pay interest on it over the life of your mortgage. In exchange, the insurer guarantees your lender will be covered if you default.
Down payment less than 20% CMHC is the trigger. If your down payment is 20% or more, you do not need default insurance. If it is under 20%, you must have it with one of the three approved insurers, CMHC, Sagen, or Canada Guaranty.

CMHC Insurance and the Stress Test
Mortgage stress test insured vs uninsured Canada is one of the most misunderstood parts of Canadian mortgage rules.
How the Stress Test Works
For CMHC insured mortgages (less than 20% down), you qualify at the higher of:
- Contract rate + 2%, the standard buffer applied to all borrowers
- OSFI mortgage stress test floor of 5.25% (or the current minimum qualifying rate), whichever is higher
For uninsured mortgages (20%+ down), you qualify at contract rate + 2% only.
CMHC insurance stress test 5.25% Canada, with five-year fixed rates sitting around 5.49% to 6.49% in mid-2026, the insured borrower qualifies at roughly 5.25% to 7.49%, while the uninsured borrower qualifies at 7.49% to 8.49%. Because the insured floor is lower, a buyer with 5% down can qualify for a larger mortgage than a buyer with 20% down in many cases, our guide on how much house you can afford in Canada breaks down scenarios with real numbers.
OSFI mortgage stress test floor 5.25% has not changed in 2026, though discussions about adjusting it continue. Mortgage stress test 2026 Canada insured rules remain the same.
GDS TDS ratio CMHC insured mortgage, 39% GDS and 44% TDS are the maximums for CMHC-insured mortgages. CMHC insurance GDS TDS ratio impact Canada means every dollar of CMHC premium added to your balance increases your monthly payment slightly, which pushes your GDS higher.
Minimum Down Payment Canada 2026
Minimum down payment Canada 2026 follows a graduated structure:
- 5% for homes up to $500,000
- 5% on first $500k + 10% on the portion above $500k for homes $500k–$999,999
- 20% for homes at $1 million or more (CMHC insurance not available at this price)
Graduated down payment Canada calculation example: a $750,000 home needs $25,000 (5% of $500,000) + $25,000 (10% of $250,000) = $50,000 minimum down.
Minimum down payment $1 million home 2026, 20% = $200,000. CMHC is not available above $999,999, so you need either 20% down or a lender willing to accept a private insurer (rare at this price point).
Down payment rules Canada 2026 update, no changes this year. The graduated structure remains.

How Other Countries Handle Mortgage Insurance
USA: PMI and FHA MIP
The US has two systems that parallel CMHC:
Conventional PMI, monthly premium on loans with less than 20% down. Cancelable at 80% LTV. Unlike CMHC's single upfront premium, US PMI is monthly and stops when you reach enough equity. For a buyer who plans to build equity quickly, PMI costs less than CMHC over time.
FHA MIP, 1.75% upfront + 0.80% to 1.05% annual. On 30-year loans with less than 10% down, MIP lasts for the full loan term. This is closer to CMHC in structure: an upfront premium plus ongoing costs. But FHA MIP is monthly, not a single add-on.
The key difference: CMHC is a one-time cost you pay interest on. US PMI is a monthly cost you can cancel. Which is better depends on how long you keep the loan.
UK: No Direct Equivalent
The UK does not have mortgage default insurance like CMHC. Instead, lenders manage low-deposit risk through higher interest rates on high-LTV products. A borrower with 5% down pays a higher rate than someone with 20% down, the risk is priced into the interest rate, not separated as an insurance premium.
The UK's 95% mortgage guarantee scheme (government-backed) is the closest equivalent to CMHC, it insures lenders against losses on high-LTV loans, but it is the government, not the borrower, who pays.
Australia: Lenders Mortgage Insurance
Australia's LMI is the closest equivalent to CMHC. Key differences:
- LMI is a one-time premium (like CMHC), not monthly (like US PMI)
- LMI cannot be canceled, once paid, it stays
- LMI costs range from 1.0% to 4.0%, lower than CMHC's 2.80% to 4.00% at equivalent LVRs
- The First Home Guarantee (5% deposit scheme) lets eligible buyers avoid LMI entirely
Australia's LMI market is more competitive than Canada's, with multiple insurers and lender-based pricing that can vary significantly.
The Bottom Line
CMHC mortgage insurance 2026 is a cost that adds roughly 2.80% to 4.00% to your mortgage, but it also gets you into a home years earlier than waiting for 20% down. In markets where prices rise faster than you can save, buying with CMHC today beats waiting for 20% tomorrow.
