How Mortgages Work in Canada: A Complete Mortgage Guide

A mortgage is a loan you use to buy a home, secured by the property itself. In Canada, you make regular payments — typically monthly — that cover both the principal (the amount borrowed) and the interest charged by the lender. Your home serves as collateral: if you stop making payments, the lender can take possession. This guide explains the key parts of a Canadian mortgage, from down payment to amortization, so you can approach home buying with confidence.

Core Components of a Canadian Mortgage

Every mortgage in Canada is built around a few essential elements. Understanding these will help you compare offers and choose what fits your situation.

• Down payment: The minimum is 5% of the purchase price for homes under $500,000. For homes between $500,000 and $999,999, you need 5% on the first $500,000 and 10% on the remainder. Above $1 million, the minimum down payment is 20%.
• Interest rate: This is the cost of borrowing, expressed as a percentage. It can be fixed (same rate for the entire term) or variable (fluctuates with the prime rate set by the Bank of Canada).
• Amortization: The total length of time it will take to fully pay off the mortgage, usually 25 years for a first-time buyer. A longer amortization means lower monthly payments but more total interest paid.
• Term: The length of your current contract with the lender, commonly 1 to 5 years. At the end of the term, you renew or renegotiate your rate.
• Credit score: Your credit history with Equifax or TransUnion Canada influences the interest rate and approval. A higher score (usually 680 or above) qualifies you for better rates.

How Mortgage Payments Work

Your monthly payment is calculated based on the loan amount, interest rate, and amortization period. In Canada, most mortgages use a semi-annual compounding schedule for fixed rates, though some lenders compound more frequently. Each payment first covers the interest due, and the remainder reduces the principal. Over time, as the principal shrinks, more of your payment goes toward the principal — this is called amortization. You can also make prepayments (within limits set by your lender) to pay off the mortgage faster and save on interest.

Key Mortgage Types in Canada

Most Canadian mortgages fall into two categories: conventional and high-ratio. A conventional mortgage requires a down payment of 20% or more, and you do not need mortgage default insurance. A high-ratio mortgage has a down payment below 20%, and you must buy insurance from the Canada Mortgage and Housing Corporation (CMHC) or a private insurer. This insurance protects the lender, not you. Additionally, you can choose between an open mortgage (more flexible, higher rate) and a closed mortgage (lower rate, but penalties for early payout).

Refinancing and Renewal Options

If you already have a mortgage, you may consider refinance to access equity, lower your rate, or change your term. Refinancing involves breaking your current mortgage, which may trigger a penalty — typically three months' interest or the interest rate differential. Always read your mortgage contract. At renewal, you can switch lenders without penalty as long as you stay within your current amortization. Shopping around at renewal can save thousands over the life of the loan.

Steps to Get a Mortgage in Canada

First, check your credit score with Equifax and TransUnion Canada — both are used by lenders. Next, save for your down payment and document your income, debts, and assets. Get pre-approved by a lender or broker to know your budget. When you find a home, your lender will arrange an appraisal and final approval. At closing, you sign the mortgage agreement and pay any closing costs (typically 1.5% to 4% of the purchase price). After that, you make regular payments until the mortgage is paid off or you sell the property. This guide is general educational content and not financial advice.
