Introduction
If you're buying a home in Canada with a down payment of less than 20%, you’ll be required to purchase mortgage default insurance. This insurance protects the lender — not the borrower — but it plays a major role in helping first‑time homebuyers enter the market with a smaller down payment. Understanding how mortgage default insurance works helps you plan your budget and make informed decisions about your mortgage options.
What Is Mortgage Default Insurance?
Mortgage default insurance (often called “CMHC insurance”) is a mandatory insurance premium added to your mortgage when your down payment is less than 20%. It protects the lender in case you’re unable to make your mortgage payments.
Key points:
Required for high‑ratio mortgages
Allows buyers to purchase a home with as little as 5% down
Premium is added to your mortgage amount
Does not protect the homeowner — it protects the lender
Who Provides Mortgage Default Insurance in Canada?
There are three approved mortgage insurers:
1. CMHC (Canada Mortgage and Housing Corporation)
The most well‑known and government‑backed insurer.
2. Sagen (formerly Genworth Canada)
A private mortgage insurer.
3. Canada Guaranty
Another private insurer offering competitive options.
All three follow similar guidelines, but premiums and programs may vary slightly.
When Do You Need Mortgage Default Insurance?
You must purchase mortgage default insurance if:
Your down payment is less than 20%
Your home price is under $1 million
You are applying for a high‑ratio mortgage
Homes over $1 million are not eligible for insured mortgages, meaning you must put down at least 20%.
How Much Does Mortgage Default Insurance Cost?
The cost is based on your loan‑to‑value ratio (LTV) — essentially, how much you’re borrowing compared to the home’s price.
Typical premium ranges:
5% down: Highest premium
10% down: Lower premium
15% down: Even lower premium
Premiums are usually between 2.8% and 4% of the mortgage amount, depending on your down payment.
Example:
If your mortgage is $500,000 and your premium is 4%:
Insurance premium = $20,000
New mortgage total = $520,000
This amount is added to your mortgage, not paid upfront.
Benefits of Mortgage Default Insurance
While the insurance protects the lender, it also offers important advantages for buyers.
1. Lower Down Payment Requirements
You can buy a home with as little as 5% down.
2. Competitive Interest Rates
Insured mortgages often come with lower interest rates because they carry less risk for lenders.
3. Easier Qualification
Lenders may be more flexible with insured mortgages.
Drawbacks of Mortgage Default Insurance
It’s important to understand the trade‑offs.
1. Higher Overall Mortgage Amount
The premium increases your total mortgage balance.
2. Higher Monthly Payments
Because the premium is added to your mortgage, your payments increase.
3. Only Available for Homes Under $1M
Buyers in high‑priced markets may not qualify.
How to Reduce Your Mortgage Default Insurance Premium
Here are ways to lower your cost:
1. Increase Your Down Payment
Even moving from 5% to 10% can significantly reduce your premium.
2. Choose a Shorter Amortization
Shorter amortizations can reduce risk and lower premiums.
3. Improve Your Financial Profile
A stronger application may give you access to better lender options.
Mortgage Default Insurance vs. Home Insurance
These two are often confused, but they serve completely different purposes:
Type | Protects | Required? |
Mortgage Default Insurance | Lender | Required with <20% down |
Home Insurance | Homeowner | Required by lenders for property protection |
Final Thoughts
Mortgage default insurance is a key part of the Canadian home‑buying process, especially for first‑time buyers. While it adds to your mortgage cost, it also makes homeownership more accessible by allowing you to buy with a smaller down payment and secure competitive interest rates. Understanding how it works helps you plan your budget and choose the mortgage option that best supports your financial goals.
