What Is a Mortgage and Why It Matters for Canadian Buyers

Buying a home is one of the biggest financial decisions most Canadians will ever make, and unless you’re paying entirely in cash, a mortgage is the key that makes homeownership possible. But what exactly is a mortgage? How does it work in Canada? And why is it so important for buyers to understand their options before signing on the dotted line?

In this blog, I’ll break down the basics of mortgages in plain language. We’ll cover what a mortgage is, how it works in Canada, the main types of mortgages available, and why a mortgage is essential for most buyers. Plus, I’ll share some expert advice to help you choose the mortgage that fits your needs best.

What Is a Mortgage?

A mortgage is a type of loan that helps you buy a home. Because most people don’t have the entire purchase price saved up, they borrow money from a lender (like a bank or credit union). In return, they agree to pay the loan back over time, with interest.

The home itself is used as collateral, meaning the lender has a legal right to it if the borrower doesn’t make payments. Simply put: a mortgage makes homeownership affordable and achievable for the vast majority of Canadians.

How Does a Mortgage Work in Canada?

Mortgages in Canada are structured around a few key terms you’ll want to know:

  • Down Payment: The portion of the home’s price you pay upfront. In Canada, this is at least 5% of the purchase price (higher for homes above $500,000).
  • Amortization Period: The total length of time it will take to pay off your mortgage — usually 25–30 years.
  • Mortgage Term: The length of time your current contract lasts, often 1–5 years. At the end of each term, you’ll renew or renegotiate with your lender.
  • Principal vs. Interest: Your monthly payments include both the original amount you borrowed (principal) and the cost of borrowing it (interest).

This system allows buyers to spread out the cost of a home over many years, making it manageable within their budget.

Types of Mortgages in Canada

Not all mortgages are created equal. Understanding the main types will help you decide which option suits your needs:

  • Fixed-Rate Mortgage: Your interest rate stays the same for the entire term. Great for stability and predictable payments.
  • Variable-Rate Mortgage: The interest rate can go up or down depending on the lender’s prime rate. This can save you money if rates fall, but it carries more risk.
  • Open Mortgage: Lets you pay off your loan in full anytime without penalties — useful if you expect extra income soon.
  • Closed Mortgage: Offers lower interest rates but restricts how much you can pay off early without penalty.
  • Conventional vs. High-Ratio: If your down payment is at least 20%, you have a conventional mortgage. Less than 20% requires mortgage insurance, making it a high-ratio mortgage.

Each type has its pros and cons and choosing the right one can save you thousands over the life of your loan.

Why You Need a Mortgage When Buying a Home

Unless you have the entire purchase price ready in cash, a mortgage is the tool that turns the dream of homeownership into reality. It allows you to:

  • Afford a Home Sooner: You don’t need to wait decades to save the full amount.
  • Build Equity: As you pay down your mortgage, you build ownership in your property.
  • Plan Financially: Fixed or variable terms let you choose a repayment structure that fits your income and lifestyle.
  • Grow Wealth Over Time: Owning a home can be a long-term investment that increases in value.

Simply put: a mortgage bridges the gap between your savings and your dream home.

Tips for Choosing the Right Mortgage

Because mortgages are complex, it’s essential to make informed choices. Here are a few expert tips:

  • Understand Your Budget: Calculate not just the mortgage payments but also property taxes, insurance, and utilities.
  • Shop Around: Different lenders may offer different rates and terms and compare before committing.
  • Consider Your Future Plans: If you expect to move in a few years, a shorter mortgage term might be best.
  • Get Pre-Approved: Knowing how much you qualify for helps set realistic expectations when house hunting.
  • Work With a Professional: A mortgage broker or trusted Realtor can help explain the fine print and guide you toward the best options.

We had the absolute pleasure of working with Laurence as part of our real estate dream team with both the sale of our house and purchase of our new home. Laurence was absolutely incredible every step of the way—she helped stage our house, designed beautiful marketing materials, hosted open houses every weekend, attended home inspections, collected water samples, and was a master in negotiation… the list goes on of all the wonderful things she did for our family. She gave great advice, was there for us every step of the way, and was always available. Laurence is truly one of the most lovely, hard working and genuine people we have had the pleasure of knowing. She was positive when there were bumps in the road, supportive, and had our best interest at heart. Our 3 year old still asks when she will get to see Laurence next. She truly became part of our family, and we are so grateful to have met and worked with her.
