How Mortgage Financing Works in Canada

A mortgage is a loan used to finance a home purchase. Your down payment is applied toward the purchase price, while the mortgage generally covers the remaining amount, subject to the lender’s approval and applicable requirements.

The amount a lender is willing to provide depends on your financial circumstances and the property you want to purchase. During the mortgage application or pre-approval process, lenders may consider your income, assets, debts and other financial information. They may also require documentation to verify your financial position.

Understanding these factors before you shop for a home can help you set a more realistic financing range.

What Do Lenders Consider When Assessing a Mortgage?

Lenders don’t determine mortgage eligibility based solely on the purchase price.

During pre-approval, a lender or mortgage broker may review your income, assets and level of debt, along with information such as your employment, down payment and other financial obligations. A credit check may also form part of the process.

For example, a borrower with substantial existing debt may have a different borrowing capacity from another borrower with the same income but fewer financial obligations.

Your lender will also assess the property before providing final mortgage approval. The lender’s own policies and lending criteria can affect the final decision.

What Is Mortgage Pre-Approval?

Mortgage pre-approval is an early assessment that can help you understand how much you may be able to borrow.

Depending on the lender, a pre-approval may provide an estimated maximum mortgage amount, estimated payments and an interest-rate hold. The Financial Consumer Agency of Canada says a lender may hold a pre-approved rate for 60 to 130 days, depending on the lender.

Pre-Approval Is Not Final Approval

This distinction is important.

A pre-approval does not guarantee that the lender will approve your mortgage for a particular property. Before final approval, the lender may verify your information and assess the property against its lending requirements.

FCAC specifically notes that a lender can refuse a mortgage even after pre-approval.

For that reason, a pre-approved maximum should not automatically become your target purchase price. Your personal budget may be lower than the maximum amount a lender is prepared to offer.

How Much Down Payment Do You Need in Canada?

The minimum down payment depends on the home’s purchase price.

Under current federal rules:

Home purchase price

Minimum down payment

$500,000 or less

5% of the purchase price

More than $500,000 but below $1.5 million

5% of the first $500,000 + 10% of the portion above $500,000

$1.5 million or more

20% of the purchase price

Example: $600,000 Home

For a $600,000 home:

5% of the first $500,000 = $25,000

10% of the remaining $100,000 = $10,000

Minimum down payment = $35,000

This is an example of the current federal calculation. It does not mean that making only the minimum down payment is necessarily the best choice for every buyer.

A larger down payment means borrowing less, although buyers should also consider how much cash they want to retain for other expenses.

What Is Mortgage Loan Insurance and Provincial Tax?

If your down payment is less than 20% of the purchase price, you will typically need mortgage loan insurance, subject to the applicable requirements. Mortgage loan insurance protects the lender, not the borrower, if the borrower cannot make the mortgage payments.

The federal government increased the insured-mortgage price cap from $1 million to $1.5 million effective December 15, 2024. This allows eligible borrowers purchasing homes below $1.5 million to potentially obtain insured financing with a down payment below 20%.

The insurance premium depends on factors such as the down payment amount. FCAC currently states that premiums range from 0.6% to 4.5% of the mortgage amount. Some provinces apply provincial sales tax to mortgage loan insurance premiums. In Ontario, this tax cannot be added to the mortgage and must generally be paid as part of the buyer’s closing costs. Buyers should include it in their cash-on-closing calculation. If you add the insurance premium to your mortgage instead of paying it upfront, you will also pay interest on that amount.

Fixed vs. Variable Mortgage Rates

Mortgage interest rates generally fall into two broad categories: fixed and variable.

With a fixed-rate mortgage, the interest rate stays the same during the mortgage term. This can make the interest component of your payments more predictable during that period.

With a variable-rate mortgage, the interest rate can change during the term. Depending on the mortgage product and payment structure, rate changes can affect your payments or how much each payment goes toward principal and interest. Variable-rate mortgages may have either adjustable or fixed payments. With adjustable payments, the payment changes when the interest rate changes. With fixed payments, the payment may remain unchanged, but a rate increase directs more of each payment toward interest and less toward principal. If rates rise sufficiently, the borrower may reach a trigger point and be required to increase payments, make a lump-sum payment or address a growing mortgage balance. FCAC mortgage options 

Neither type is automatically better for every borrower. The right choice depends on your financial circumstances, your comfort with changing interest costs, and the specific mortgage contract.

Mortgage Term vs. Amortization

Term and amortization describe two different aspects of a mortgage.

The mortgage term is the period during which your current mortgage contract is in effect. When the term ends, you generally need to renew the mortgage or arrange another financing solution if you still have a balance.

The amortization period is the estimated time needed to repay the mortgage based on the payment structure and current assumptions.

A longer amortization generally lowers scheduled payments but increases the amount of interest paid over the life of the mortgage.

Current 30-Year Amortization Rules

For mortgages with a down payment of less than 20% uninsured mortgages or more, the current maximum amortization is 30 years for first-time buyers and/or those purchasing a new build. In other cases, the maximum is generally 25 years. If the down payment is more than 20%, the lender sets the maximum amortization period.

These rules can change, so buyers should confirm the applicable requirements when arranging financing.

Understanding the Mortgage Stress Test

Mortgage qualification can involve a qualifying interest rate that is higher than the rate offered on the mortgage.

FCAC’s current consumer guidance states that federally regulated financial institutions require new borrowers to pass a stress test using the higher of 5.25% or the negotiated mortgage rate plus 2 percentage points. FCAC states that this applies to both insured and uninsured mortgages. 

For an insured mortgage with a down payment of less than 20%, a maximum amortization of up to 30 years may be available when at least one borrower qualifies as a first-time home buyer, or the buyer is purchasing a qualifying new build. The maximum is generally 25 years for other insured mortgages.

OSFI separately sets the Minimum Qualifying Rate for uninsured mortgages at federally regulated lenders at the greater of the contract rate plus 2 percentage points or 5.25%.

When the down payment is 20% or more, the mortgage is generally uninsured, and the lender determines the maximum amortization it will permit. A longer amortization can lower scheduled payments but usually increases the total interest paid. 

The Straight Switch Rule

The Policy: The Office of the Superintendent of Financial Institutions (OSFI) removed the minimum qualifying rate test for uninsured “straight switches” at renewal. 

The Conditions: This exemption applies as long as you do not increase your mortgage amount or extend your amortization period when moving to the new bank.  

The Timing: This rule went into effect on November 21, 2024, making it much easier to shop around for better rates.

When the Stress Test Still Applies

You will still have to pass the stress test if you decide to:

Refinance: Borrow extra cash or increase your total loan amount during the transfer.

Extend Amortization: Lengthen the timeline you use to pay off the loan. 

The important takeaway for buyers is that the mortgage rate you see offered is not necessarily the rate used to assess your ability to qualify.

Mortgage Features That Can Affect Your Costs

The interest rate is only one part of a mortgage.

Prepayment Privileges

A mortgage may allow you to pay additional amounts toward the principal without a prepayment charge, subject to the limits in your contract.

For example, your mortgage may allow certain lump-sum payments or increases to your regular payment amount. The permitted amount varies by mortgage.

If paying down your mortgage faster is important to you, these privileges are worth comparing before choosing a product.

Prepayment Penalties

You may face a prepayment charge if you pay off your mortgage early, renegotiate before the end of your term or exceed your permitted prepayment amount. The penalty depends on the mortgage and your contract terms.

This matters more if you expect to sell your home or refinance before the mortgage term ends.

Open vs. Closed Mortgages

An open mortgage generally offers more flexibility to repay the mortgage without the same prepayment restrictions.

A closed mortgage generally has greater restrictions on early repayment, although the exact privileges and penalties depend on the contract.

Don’t compare mortgages based solely on whether they are described as open or closed. Review the actual terms.

Portability

Some mortgages are portable, meaning you may be able to transfer the mortgage to another property if you move, subject to the lender’s conditions.

If you expect your housing needs to change during your mortgage term, ask whether portability is available and what conditions apply.

What Happens When Your Mortgage Term Ends?

The end of your mortgage term does not necessarily mean your mortgage has been paid off.

If you still have a balance, you’ll generally need to renew the mortgage or arrange another financing solution.

Your new term may have a different interest rate and different conditions from your previous term.

Because most borrowers need multiple mortgage terms to fully repay a mortgage, the renewal stage can significantly affect the overall cost of borrowing.

When comparing a mortgage today, consider not only the current rate but also what your options may look like when the term ends.

How Should You Compare Mortgage Options?

Evaluate a mortgage as a complete product, not just by its advertised interest rate.

Consider the interest rate alongside the term, amortization, prepayment privileges, penalties, portability and other contractual conditions.

For example, a mortgage with a slightly lower rate may not be the best fit if it has restrictions that conflict with your plans to move, refinance or make additional payments.

FCAC recommends comparing mortgage options and understanding the associated costs and conditions before deciding.

If you’re working with a mortgage broker, ask which lenders they work with. FCAC notes that brokers do not all have access to the same lenders or mortgage products.

Questions to Ask Before Choosing a Mortgage

Before signing a mortgage agreement, make sure you understand:

What is the interest rate, and is it fixed or variable?

How long is the mortgage term?

What is the amortization period?

What prepayment privileges are included?

How are prepayment penalties calculated?

Is the mortgage portable?

What happens when the term ends?

Are there fees or restrictions that could affect me later?

These questions can help you look beyond the advertised rate and understand how the mortgage could work throughout the term.

Common Mortgage Mistakes to Avoid

Choosing Based Only on the Lowest Rate

A lower advertised rate does not necessarily mean a mortgage is the best fit. Prepayment privileges, penalties, portability, and other conditions can affect the mortgage’s overall value.

Treating Pre-Approval as Guaranteed Financing

Pre-approval indicates potential borrowing capacity. It does not guarantee final approval for a specific property.

Ignoring Prepayment Conditions

If you expect to make additional payments, sell your property or refinance before the end of the term, understand the mortgage’s prepayment rules before signing.

Choosing a Longer Amortization Without Considering the Total Cost

A longer amortization can reduce scheduled payments, but it can also increase the total interest paid over the life of the mortgage.

Making Major Financial Changes After Pre-Approval

A significant change to your income, debts or other financial circumstances can affect the mortgage process. Discuss major changes with your lender or mortgage professional before closing.

Mortgage Financing for First-Time Buyers

First-time buyers may have access to federal programs that can help them save for or finance a home.

The First Home Savings Account (FHSA) currently provides $8,000 of participation room in the first year you open an FHSA, with a $40,000 lifetime limit, subject to the applicable rules.

The Home Buyers’ Plan (HBP) currently allows eligible individuals to withdraw up to $60,000 from an RRSP to buy or build a qualifying home. CRA also confirms that eligible buyers may use an HBP withdrawal and a qualifying FHSA withdrawal for the same home when all applicable conditions are met.

Frequently Asked Questions

What is mortgage pre-approval?

Mortgage pre-approval is an assessment that can help you understand the mortgage amount you may qualify for. Depending on the lender, it may also include an interest-rate hold. Pre-approval does not guarantee final mortgage approval.

How much down payment do I need in Canada?

The minimum depends on the home’s purchase price. Current federal rules require 5% on homes priced at $500,000 or less, a tiered calculation for homes above $500,000 and below $1.5 million, and 20% for homes priced at $1.5 million or more.

Do I need mortgage loan insurance if I put less than 20% down?

Typically, yes, subject to the applicable requirements. Mortgage loan insurance protects the lender against losses if the borrower cannot make the mortgage payments.

What is the difference between a fixed and variable mortgage?

A fixed mortgage rate remains the same throughout the mortgage term, while a variable rate can change during the term. The right option depends on your circumstances and the mortgage terms.

What is the difference between mortgage term and amortization?

The mortgage term is the period during which the current mortgage contract is in effect. The amortization period is the estimated time needed to repay the mortgage under the applicable payment structure.

What is the mortgage stress test?

For federally regulated lenders, borrowers must generally qualify at a rate higher than the actual mortgage rate. FCAC currently states that the qualifying rate is the higher of 5.25% or the negotiated rate plus 2 percentage points.

Can I pay my mortgage off faster?

Your mortgage may include prepayment privileges that allow additional payments without a charge, subject to the limits in your contract. Exceeding those privileges can result in a prepayment penalty.

What happens when my mortgage term ends?

If you still have a mortgage balance at the end of the term, you’ll generally need to renew the mortgage or arrange another financing option. The new term may have different interest rates and conditions.

Can I use an FHSA and the Home Buyers’ Plan for the same home?

Yes, it may be possible if you meet the requirements for both programs. CRA confirms that an eligible individual can make a qualifying FHSA withdrawal and an HBP withdrawal for the same qualifying home, provided the applicable conditions are met.

Final Thoughts

Choosing a mortgage is about more than finding the lowest advertised interest rate.

Before committing to financing, understand how much you may qualify for, how much you plan to put down, whether mortgage insurance applies, how the interest rate works, how long the term lasts and what happens if your plans change before the mortgage is paid off.

Pay particular attention to prepayment privileges, penalties, portability and renewal terms. These features can matter if you sell, refinance, or want to pay your mortgage down faster.

For first-time buyers, programs such as the FHSA and Home Buyers’ Plan may also be relevant, but eligibility requirements apply.

A qualified mortgage professional can help you evaluate the financing options available for your particular circumstances.
