What is a CMHC-Insured Mortgage in Canada

General

Posted by: Gavin Toor

Quick Overview

A CMHC-insured mortgage is a type of home loan in Canada that lets you buy with as little as 5% down. Backed by the Canada Mortgage and Housing Corporation, it protects lenders against default, which often means better mortgage rates for buyers. While it helps first-time buyers enter the market sooner, it comes with strict qualification rules and added insurance premiums.

For many first-time home buyers in Canada, one of the biggest hurdles to owning a home is saving up the down payment. If you’re buying a property with less than 20% down, you’ll likely need a CMHC-insured mortgage. This type of mortgage allows you to purchase with as little as 5% down — but it also comes with strict qualification rules and added insurance costs.

In this article, we’ll break down what a CMHC-insured mortgage is, the pros and cons, and how to know if it’s the right choice for your home purchase.

What is a CMHC-Insured Mortgage?

CMHC stands for the Canada Mortgage and Housing Corporation, one of three national mortgage insurers (alongside Sagen and Canada Guaranty). Mortgage insurance protects the lender if you default on your loan.

Because the lender takes less risk, they’re often willing to offer better mortgage rates. For first-time buyers who don’t yet have a large down payment saved, this can make homeownership much more accessible.

Benefits of a CMHC-Insured Mortgage

✅ Lower Down Payments

  • Buy a home with as little as 5% down on the first $500,000, and 10% on the portion between $500,000–$999,999.

  • This makes entering the housing market more realistic for new buyers.

✅ Access to Competitive Rates

  • Since lenders are protected, they often pass on lower interest rates compared to uninsured options.

✅ Get Into the Market Sooner

  • You don’t have to wait years to save 20%. Instead, you can start building equity right away.

✅ Widely Accepted

  • CMHC-backed mortgages are available through all major banks, credit unions, and alternative lenders in Canada.

Drawbacks of a CMHC-Insured Mortgage

❌ Strict Qualification Rules

  • CMHC uses tight debt service ratios: 39% Gross Debt Service (GDS) and 44% Total Debt Service (TDS).

  • This can make approval harder if you have variable income or existing debts.

❌ Mortgage Insurance Premiums

  • The CMHC insurance premium ranges from 2.8% to 4.0% of your mortgage amount, depending on your down payment.

  • The cost is rolled into your mortgage, increasing the total amount you’ll repay.

❌ Purchase Price Limit

  • Only available for homes under $1 million. Anything above requires a 20% down payment.

❌ Owner-Occupied Requirement

  • CMHC-insured mortgages are for owner-occupied properties only. Rental and investment properties don’t qualify.

Is a CMHC-Insured Mortgage Right for You?

For many first-time buyers in Canada, CMHC insurance is the tool that makes buying possible. It allows for a smaller down payment, often with more competitive rates.

However, the strict qualification rules and extra premium cost mean it’s not always the best choice for every buyer. That’s why it’s so important to prepare early.

One of the best steps you can take is to start planning well before your completion date. My post on The 90-Day Pre-Completion Mortgage Checklist explains exactly what to review in the months leading up to closing so you’re not caught off guard.
