What is a High-Ratio Mortgage and Why Are Rates Lower?Can’t believe how much houses cost these days? With prices climbing across Canada, saving for a traditional 20% down payment feels impossible for many. That’s why high-ratio mortgages are becoming so popular – they let you buy a home with less money up front. But here’s the kicker: these mortgages, where you actually pay less initially, often come with lower interest rates. Why? This blog will break down high-ratio mortgages in Canada, explaining how they work, who’s eligible, and why those seemingly backwards interest rates exist. What Is a High-Ratio Mortgage?Essentially, a high-ratio mortgage means you’re putting down less than 20% on a property. This makes the loan itself a bigger chunk of the home’s value – that’s called the Loan-to-Value (LTV) ratio. If your LTV is over 80%, you need to get mortgage insurance from either the Canada Mortgage and Housing Corporation (CMHC), Sagen, or Canada Guaranty. If you are unable to make your payments, this insurance protects the lender, not you. The opposite is true for a traditional mortgage. Mortgage insurance is not required for down payments of 20% or greater. The idea is simple: with a bigger down payment, you’re less likely to default, so the bank isn’t as worried. Think saving a 20% down payment is a pipe dream? A high LTV mortgage in Canada could be your ticket to owning a home. How High-Ratio Mortgages Work in PracticeOkay, let’s walk through getting a CMHC-insured mortgage, or one from Sagen or Canada Guaranty:
Here’s an example: say you’re buying a $600,000 house and putting 10% down ($60,000). That means you need a $540,000 mortgage. If the insurance premium is 4%, that adds $21,600 to your loan. So, your total original mortgage amount becomes $561,600. And don’t forget, these fees don’t exclude you from first-time homebuyer programs and incentives. Why Are High-Ratio Mortgage Rates Lower?So, why are high-ratio mortgage rates usually lower than regular mortgage rates? It all comes down to risk, or more specifically, the lender’s reduced risk.

Role of High-Ratio Mortgage InsuranceImportant: mortgage insurance from CMHC, Sagen, and Canada Guaranty protects the lender, not you. But it’s thanks to this insurance that you can buy a home with a smaller down payment. The size of your down payment (the loan-to-value ratio) determines the cost of the insurance. A higher LTV and a higher premium are associated with a lesser down payment. This charge is added to your mortgage when you make a single payment. Also, heads up, some provinces charge sales tax on this premium. Before you jump in, get your finances sorted. Our article, Steps to Take Before Applying for a Mortgage, has some great tips.
