Insured vs Uninsured Mortgages: What's the Difference?

Understand the difference between insured (CMHC) and uninsured mortgages. Jay Klair explains how down payments impact your interest rates in Ontario.

In Canada, the amount of your down payment determines whether you have an insured or an uninsured mortgage. If you have less than 20 percent of the purchase price, you are required by law to have mortgage default insurance, often provided by CMHC, Sagen, or Canada Guaranty. While this insurance protects the lender, not you, it actually allows you to access lower interest rates because the lender's risk is virtually eliminated. For many first-time buyers in Ontario, an insured mortgage is the only way to enter the market with as little as five percent down. The insurance premium is typically added to your mortgage balance, so you do not need to pay it upfront.

Uninsured mortgages, on the other hand, are for buyers with 20 percent or more as a down payment or for properties valued at over one million dollars. Because these loans are not backed by the government or private insurers, lenders often charge slightly higher interest rates to account for the increased risk they carry. However, uninsured mortgages offer more flexibility, such as the ability to extend your amortization to 30 years, which is not available for standard insured products on resale homes. This can be a significant benefit for managing monthly cash flow in expensive markets like Oakville or Toronto. Balancing the lower rate of an insured mortgage against the flexibility of an uninsured one is a key part of our strategy.

The maximum purchase price for an insured mortgage in Canada is currently capped at one million dollars. If you are looking at a home priced at 1.1 million dollars, you must have at least 20 percent down, as insurance is no longer an option regardless of your income level. This creates a significant 'gap' for buyers in the GTA where many detached homes exceed the million-dollar mark. For these high-value purchases, your credit score and income must be exceptionally strong to qualify for the best uninsured rates. We will look at your available capital and decide if pushing for a 20 percent down payment is better than paying the insurance premium for your specific case.

I recommend that you run two sets of numbers with me: one with 15 percent down (insured) and one with 20 percent down (uninsured). Sometimes, keeping that extra five percent in your pocket for renovations or investments is more beneficial than the small monthly savings from a lower interest rate. We can compare the total cost over a five-year term to see which path puts you further ahead financially. Every buyer's situation is different, and there is no right or wrong answer without looking at your full financial picture. Call me to discuss how your down payment size will dictate your mortgage options and total costs.
