For many first-time homebuyers in Burnaby and Vancouver, saving a 20% down payment can feel like an impossible task. That's where mortgage default insurance, often referred to as CMHC insurance, comes into play. While it allows you to buy a home with a smaller down payment, it's a cost that's often misunderstood. Let's clear up what CMHC mortgage insurance is, why it's required in BC, and how it impacts your home purchase.
What is CMHC Mortgage Insurance?
CMHC stands for Canada Mortgage and Housing Corporation, a Crown corporation that provides mortgage default insurance. This insurance protects lenders (banks, credit unions, etc.) against losses if a borrower defaults on their mortgage payments. It's important to understand that this insurance protects the lender, not you, the homeowner, directly. However, it's a crucial mechanism that enables lenders to offer mortgages to buyers with down payments less than 20%.
Why is CMHC Insurance Required in BC (and Canada)?
In Canada, if your down payment is less than 20% of the home's purchase price, your mortgage is considered a 'high-ratio' mortgage and must be insured against default. This requirement is mandated by federal regulations. While CMHC is the largest provider, there are also two other private insurers: Sagen (formerly Genworth Canada) and Canada Guaranty. The terms and costs are largely similar across all three.
Without this insurance, lenders would face a much higher risk, making it difficult for many Canadians to access homeownership. CMHC insurance effectively lowers the risk for lenders, allowing them to provide mortgages with down payments as low as 5% for properties under $500,000, and 10% for the portion between $500,000 and $999,999.
How is the CMHC Premium Calculated?
The cost of CMHC insurance is called a premium, and it's calculated as a percentage of your total mortgage amount. The premium rate depends on the size of your down payment relative to the purchase price (your loan-to-value ratio). The lower your down payment, the higher the premium.
Table: CMHC Premium Rates (Example)
| Down Payment Percentage | CMHC Premium Rate (on Mortgage Amount) |

Note: These rates are examples and are subject to change by CMHC and other insurers. They are typically added to your mortgage amount.
How CMHC Insurance Impacts Your Mortgage
- Enables Lower Down Payments: The most direct impact is that it makes homeownership accessible with less upfront cash.
- Increased Mortgage Amount: The premium is usually added to your mortgage, increasing your overall loan amount and, consequently, your monthly payments and total interest paid over time.
- One-Time Cost: Although paid over time, the premium itself is a one-time charge, not a recurring annual fee like property taxes.
- No Direct Benefit to You: Remember, the protection is for the lender. While it enables your mortgage, it doesn't provide you with direct financial assistance if you face payment difficulties.
Is There a Way to Avoid CMHC Insurance?
Yes, the primary way to avoid CMHC mortgage insurance is to make a down payment of 20% or more of the home's purchase price. If you can achieve this, your mortgage will be considered a 'conventional' mortgage, and insurance will not be required. For many in Burnaby and Vancouver, saving this much can be challenging, but it's a goal worth considering due to the savings on the premium and associated interest.
Another scenario where CMHC insurance might not apply is for certain types of private mortgages or if you're refinancing with sufficient equity. However, for most standard purchases with less than 20% down, it's a necessary part of the equation.

FAQ: CMHC Mortgage Insurance
Q: Does CMHC insurance protect me if I lose my job and can't make payments?
A: No, CMHC mortgage insurance protects the lender in case you default on your mortgage. It does not provide income replacement or direct financial assistance to you as the borrower.
Q: Can I pay the CMHC premium upfront instead of adding it to my mortgage?
A: While it's typically added to your mortgage, some lenders may allow you to pay a portion or all of the premium upfront. However, this is less common and would depend on your lender's policies.
Q: Are there other mortgage insurers besides CMHC?
A: Yes, in Canada, Sagen (formerly Genworth Canada) and Canada Guaranty are the other two main providers of mortgage default insurance. Lenders work with all three, and the premiums and requirements are very similar.
Q: Does CMHC insurance apply to all types of properties?
A: CMHC insurance is generally for residential properties with up to four units, provided one unit is owner-occupied. There are specific rules for different property types, including rental properties and second homes.
