Understanding Canadian Mortgages

The Canadian mortgage landscape is unique, governed by specific regulations in the Interest Act and the Bank Act. Whether you are buying a trendy condo in Toronto, a family home in Calgary, or an investment property in Vancouver, understanding how interest is calculated and how insurance premiums work can save you thousands of dollars.

Semi-Annual Compounding: The Canadian Standard

One of the most distinctive features of Canadian fixed-rate mortgages is that interest is compounded semi-annually (twice a year) but paid monthly. This is a legal requirement for all fixed-rate mortgages in Canada. For the borrower, this is actually a slight advantage; it means the effective interest rate is slightly lower than if the same annual rate were compounded monthly (the US standard).

Variable-rate mortgages in Canada, however, are typically compounded monthly, matching the frequency of the payments.

CMHC Insurance and the 20% Rule

In Canada, if your down payment is less than 20% of the home's purchase price, you must obtain mortgage default insurance. While there are private providers like Sagen and Canada Guaranty, this is most commonly provided by the Canada Mortgage and Housing Corporation (CMHC).

The insurance premium is a one-time fee calculated as a percentage of your loan amount. It decreases as your down payment increases:

5.0% to 9.99% Down: 4.00% Premium

10.0% to 14.99% Down: 3.10% Premium

15.0% to 19.99% Down: 2.80% Premium

20% or More Down: 0% Premium (Insurance not required)

Most buyers choose to "roll" this premium into their mortgage balance rather than paying it upfront in cash.

Minimum Down Payment Requirements

Canada has a tiered system for minimum down payments designed to ensure housing market stability:

Price up to $500,000: 5% of the total price.

Price $500,001 to $999,999: 5% on the first $500k, and 10% on the remaining balance.

Price $1,000,000 or more: A flat 20% minimum is required (no CMHC insurance available for homes over $1M).

Amortization vs. Term

It is crucial to distinguish between the amortization period and the mortgage term.

The Amortization Period is the total length of time it would take to pay off the mortgage in full (e.g., 25 years). For insured mortgages, the maximum amortization is 25 years. For uninsured mortgages (20% down or more), 30-year amortizations are common.

The Mortgage Term is the length of your current contract with the lender (e.g., 5 years). At the end of the term, you must either pay off the remaining balance or "renew" your mortgage for a new term at the then-current market interest rates.

Closing Costs in Canada

In addition to your down payment, you should budget 1.5% to 4% of the purchase price for closing costs, which include:

Land Transfer Tax: Varies by province (and city, in Toronto's case).

Legal Fees: Usually $1,000 - $2,500.

Title Insurance: $250 - $500.

Appraisal Fee: $300 - $500.

PST on CMHC Premium: In provinces like Ontario, Quebec, and Saskatchewan, you must pay provincial sales tax on the insurance premium upfront, even if the premium itself is rolled into the loan.
