Mortgage in Canada: How does it work?

In Canada, a mortgage allows you to borrow the money needed to buy a house, condo, or building. Repayment occurs over several years, depending on various factors such as the mortgage rate, amortization, down payment, and loan type.

In this guide, discover how mortgages work in Canada, approval criteria, the differences between fixed and variable rates, and the main elements to understand before buying a property.

How does a mortgage work?

In Canada, most buyers use a mortgage to finance the purchase of a house, condo, or building.

Your down payment represents the portion paid upfront. The mortgage then covers the difference between this amount and the property’s purchase price.

A mortgage is an agreement made with a lender, such as a bank or credit union. In exchange for financing, you make regular payments over several years.

Mortgage payments generally include:

During the repayment period, you will also need to renew your mortgage at the end of each term. Penalties may apply if you repay the loan before its due date.

Mortgage Payment Frequency

Payment frequency determines how often you repay your mortgage.

The main options offered in Canada are:

Some accelerated frequencies can slightly reduce the loan term and the total interest paid.

Types of Mortgages

There are several types of mortgages in Canada. The right choice depends on your budget, financial flexibility, and long-term plans.

Some mortgages allow more flexible prepayments, while others offer more advantageous interest rates. Here are the main options offered by mortgage lenders.

Before choosing a mortgage type, it’s important to assess your repayment horizon, risk tolerance, and financial capacity. Comparing several mortgage lenders can also help you find more favorable conditions.

How much does it cost to buy a house?

To buy a property in Canada, you generally need to provide a down payment. This amount represents the portion paid immediately before obtaining a mortgage.

The minimum down payment varies depending on the property’s purchase price (federal rules checked on October 26, 2026 on the Financial Consumer Agency of Canada website):

If your down payment is less than 20%, you will generally have to pay mortgage loan insurance, often called CMHC insurance.

The higher your down payment, the lower the amount borrowed and the interest paid will be.

Costs associated with a mortgage

CMHC insurance

Mortgage loan insurance, often called CMHC insurance, protects the lender in case of default.

In Canada, this insurance is generally mandatory when the down payment is less than 20% of the purchase price. Its cost is usually added to the mortgage and repaid with the payments.

In some situations, the lender may also require mortgage insurance despite a higher down payment, especially if the credit file presents a higher risk.

Property taxes

Some lenders add property taxes directly to mortgage payments.

The financial institution then collects the amounts related to municipal and school taxes before paying them to the municipality.

This option can simplify budget and payment management.

Lender Criteria

Mortgage lenders evaluate several elements before approving a financing application. Their goal is to determine your ability to repay the loan without difficulty.

Among the main criteria analyzed are your income, financial stability, credit file, and debt level.

Debt Ratios

Debt ratios are a central element of lenders’ analysis. They measure the weight of your debts relative to your income.

In Canada, financial institutions primarily use two ratios:

These indicators are used to assess your ability to take on a mortgage, taking into account your other financial obligations, such as credit cards, car loans, or lines of credit.

In addition, lenders use these ratios to determine the income needed to support mortgage payments based on your situation.

The Stress Test

The stress test is a regulatory requirement in Canada to obtain an insured or conventional mortgage.

It aims to verify your ability to continue making your payments even if interest rates increase.

Specifically, lenders evaluate your application using a rate higher than your mortgage contract rate. This rate generally corresponds to the higher of:

This test also applies when refinancing or applying for a home equity line of credit.

Good debt management and a strong credit file can improve your chances of obtaining a mortgage with better conditions.

How do you get pre-approved?

A mortgage pre-approval allows you to estimate the amount a lender could grant you before purchasing a property. This step also helps you know the interest rate for which you could be eligible.

To obtain pre-approval, financial institutions analyze several elements of your financial situation. They check your income, job stability, down payment, and credit file.

Lenders also assess your debt level to determine if your mortgage payments will remain affordable within your budget.

Before submitting an application, it can be helpful to reduce certain debts and improve your credit score to obtain better financing conditions.

Steps to Obtain a Mortgage

Obtaining a mortgage in Canada generally involves several steps:

Many buyers also work with a mortgage broker to compare different financing offers.

How to choose your mortgage

Choosing a mortgage is not limited to the interest rate. Several factors influence the total cost and flexibility of your mortgage.

You must consider the type of lender, the contract term, the repayment period, the interest rate, and your payment frequency.

These elements can have a significant impact on the total amount paid over the life of your mortgage.

Types of Mortgage Lenders

In Canada, several types of lenders offer mortgages.

These include:

Mortgage brokers, like nesto, can compare several offers to help you find a more advantageous rate.

Each type of lender can offer different conditions. It is therefore important to compare before making a decision.

Mortgage Term

A mortgage term corresponds to the duration of your contract with the lender.

In Canada, terms generally range from a few months to five years or more. At the end of each term, you must renew your mortgage according to market conditions.

The interest rate, repayment conditions, and flexibility can vary from one term to another.

It is therefore important to choose a term suited to your financial strategy and risk tolerance.

Amortization Period

The amortization period is the time required to fully repay your mortgage.

In Canada, it is generally 15, 20, or 25 years.

The longer the amortization period, the lower your monthly payments. However, you will pay more interest in the long term.

Conversely, a shorter period reduces the total cost of your loan but increases your monthly payments.

For insured loans (down payment less than 20%), the maximum period is 25 years, or 30 years for a first-time buyer or a newly built home (since December 15, 2024).

Interest rate

The interest rate is one of the main factors influencing the total cost of your mortgage. The higher the rate, the more interest you will pay over the life of your mortgage.

This rate depends on several factors, including:

It is possible to negotiate your interest rate or compare several offers to obtain better conditions. Even a slight difference in rate can represent significant savings over the life of the loan.

To facilitate comparison, you can use our mortgage rate comparison tool.

Fixed or variable rate

The choice between a fixed or variable rate mainly depends on your budget and risk tolerance.

A fixed rate offers stable payments throughout the term. This option facilitates financial planning and protects against interest rate increases.

The variable rate changes according to the Bank of Canada’s key interest rate. It can reduce borrowing costs when rates fall, but payments or interest can also increase.

Before choosing, compare different scenarios based on your financial situation and goals. You can also consult our guide on fixed or variable rate mortgages.

What happens if rates go up?

An increase in interest rates can raise the total cost of a mortgage, especially with a variable-rate loan.

In this case, payments or the interest portion can increase rapidly when the key rate rises.

With a fixed-rate loan, the impact is mainly felt at the time of mortgage renewal.

The Bank of Canada’s decisions therefore directly influence the evolution of mortgage rates. To follow current trends, consult our analysis of the Bank of Canada’s key interest rate.

Mistakes to avoid

Certain mistakes can increase the total cost of your mortgage or complicate the approval of your loan. Here are the most common ones.

Buying at your maximum capacity

Even if a lender approves you for a high amount, it doesn’t necessarily mean that this budget is suitable for your financial situation.

It is important to maintain a margin of maneuver to absorb unforeseen events, rate increases, or property-related expenses.

Neglecting closing costs

Many buyers forget to budget for certain additional costs, such as taxes, notary fees, inspection, or moving expenses.

These costs can amount to several thousands of dollars and must be integrated into your budget from the outset.

Not comparing mortgage rates

Discrepancies between mortgage lenders can be significant. Even a slight difference in rate can represent thousands of dollars over the life of the mortgage term.

Before signing an offer, take the time to compare several options using the mortgage rate comparison tool in Canada.

Forgetting the impact of your credit file

Your credit score directly influences the financing conditions offered by lenders.

Late payments or high debt can reduce your chances of obtaining the best available rates.

Conclusion

A mortgage is a significant financial commitment that allows you to finance the purchase of a property in Canada with a down payment and repayment over several years.

Before choosing, carefully compare the interest rate, term, amortization, and loan type.

In a context of still high rates in 2026, a slight difference in rate can represent thousands of dollars over the life of the loan.
