A Mortgage Glossary is a collection of important mortgage-related terms and their definitions. It acts as a reference guide that helps homebuyers, homeowners, and investors understand the language used in the mortgage industry. This glossary includes commonly used terms such as mortgage term, amortization, fixed rate, variable rate, refinancing, prepayment penalty, and many others.

Buying a home is one of the biggest financial decisions you’ll ever make, but understanding the language of mortgages can often feel overwhelming. Whether you’re purchasing your first home, renewing an existing mortgage, or refinancing your property, you’ll come across terms that may seem unfamiliar.

The good news is that mortgage terminology doesn’t have to be complicated. Once you understand the key terms, you’ll be better equipped to compare mortgage options, communicate with lenders and brokers, and make confident financial decisions.

This mortgage glossary explains the most common mortgage terms in simple, easy-to-understand language. Think of it as your go-to reference whenever you’re navigating the Canadian mortgage process.

Mortgage

A mortgage is a loan used to purchase a home or other real estate. Instead of paying the full purchase price upfront, you borrow money from a lender and repay it over time through regular mortgage payments. The property acts as security for the loan until the mortgage has been paid in full.

Most mortgage payments include both the principal—the amount you borrowed—and interest, which is the cost of borrowing the money. Depending on your agreement, your payments may also include property taxes or insurance.

Mortgage Term

One of the most misunderstood mortgage terms is the mortgage term.

A mortgage term is the length of time your current mortgage agreement remains in effect. During this period, your interest rate, payment amount, and the conditions of your mortgage remain unchanged. At the end of the term, you may choose to renew your mortgage, negotiate new terms, switch lenders, or pay off the remaining balance.

Common mortgage terms in Canada include:

• 6 months
• 1 year
• 3 years
• 5 years
• 7 years
• 10 years

It’s important to remember that your mortgage term is not the same as the amount of time it takes to pay off your mortgage.

Amortization Period

The amortization period is the total number of years it will take to completely repay your mortgage, assuming you continue making your scheduled payments.

For many Canadian homeowners, a 25-year amortization is common, although shorter or longer periods may be available depending on your financial situation.

The amortization period has a significant impact on both your monthly payment and the total interest you will pay.

A longer amortization lowers your monthly payment but increases the total interest paid over the life of your mortgage. A shorter amortization requires higher monthly payments but helps you become mortgage-free sooner while reducing the amount of interest you pay.

Fixed Rate Mortgage

A fixed-rate mortgage offers stability and predictability.

With this type of mortgage, your interest rate remains the same throughout your mortgage term. As a result, your regular mortgage payments stay consistent, making it easier to budget for your monthly expenses.

A fixed-rate mortgage may be a good choice if you:

• Prefer stable monthly payments.
• Want protection against rising interest rates.
• Like knowing exactly how much you’ll pay throughout your mortgage term.

Variable Rate Mortgage

A variable-rate mortgage has an interest rate that can change as market interest rates change.

When interest rates decrease, a larger portion of your payment goes toward reducing your mortgage balance. If rates increase, more of your payment goes toward interest.

A variable-rate mortgage may be suitable if you:

• Are comfortable with changing interest rates.
• Can manage some payment uncertainty.
• Are looking for potential long-term savings.

Open Mortgage

An open mortgage gives you maximum flexibility.

With an open mortgage, you can repay your mortgage in full or make large prepayments at any time without paying a prepayment penalty. Because of this flexibility, open mortgages generally have higher interest rates than closed mortgages.

An open mortgage may be appropriate if you expect to:

• Sell your home soon.
• Refinance in the near future.
• Receive a large sum of money that you plan to use toward your mortgage.

Closed Mortgage

A closed mortgage is the most common type of mortgage in Canada.

It generally offers lower interest rates than an open mortgage. However, if you repay your mortgage early or refinance before your mortgage term ends, your lender may charge a prepayment penalty.

A closed mortgage is often a good option if you:

• Plan to keep your mortgage for the full term.
• Want a lower interest rate.
• Do not expect major financial changes in the near future.

Conventional Mortgage

A conventional mortgage is a mortgage where your down payment is at least 20% of the home’s purchase price or appraised value.

Because the lender assumes less risk, mortgage default insurance is generally not required.

High-Ratio Mortgage

A high-ratio mortgage is a mortgage where the down payment is less than 20%.

In most cases, these mortgages require mortgage default insurance from an approved mortgage insurer. This insurance protects the lender if the borrower defaults on the mortgage.

Mortgage Default Insurance (CMHC Insurance)

Mortgage default insurance is typically required for high-ratio mortgages.

The insurance protects the lender—not the borrower—if mortgage payments cannot be made. Although the lender receives the protection, the insurance premium is generally paid by the borrower as part of the mortgage financing.

Refinancing

Refinancing means replacing your current mortgage with a new mortgage.

Homeowners often refinance to:

• Access home equity.
• Consolidate higher-interest debt.
• Finance home renovations.
• Obtain different mortgage terms.
• Adjust their overall financial strategy.

Depending on your mortgage agreement, refinancing before the end of your mortgage term may result in a prepayment charge.

Maturity Date

The maturity date is the final day of your current mortgage term.

When your mortgage reaches its maturity date, you can renew the mortgage, negotiate a new agreement, switch lenders, or pay off the remaining balance without early repayment penalties.

Prepayment Charge (Prepayment Penalty)

A prepayment charge is a fee that may apply when you repay all or part of your mortgage before your mortgage term ends.

Common situations that may trigger a prepayment charge include:

• Selling your home before the end of your mortgage term.
• Refinancing your mortgage.
• Paying off your mortgage early.

Many lenders calculate the penalty using whichever amount is greater:

• Three months’ interest.
• Interest Rate Differential (IRD).

Because every lender has different rules and mortgage products, it’s always a good idea to review your mortgage agreement before making changes.

Interest Rate Differential (IRD)

The Interest Rate Differential (IRD) is one method lenders use to calculate a prepayment penalty.

In simple terms, it compares the interest rate on your current mortgage with the lender’s current rate for a mortgage that has a similar amount of time remaining in its term. If the difference between the two rates is significant, the IRD calculation may result in a higher penalty than three months’ interest.

Prepayment Privileges

Many Canadian mortgages include prepayment privileges that allow homeowners to pay off their mortgage faster without paying additional penalties, provided they stay within the limits outlined in their mortgage agreement.

Depending on your lender, these privileges may allow you to:

• Make annual lump-sum payments.
• Increase your regular mortgage payment.
• Increase your payment frequency from monthly to bi-weekly or weekly.
• Make additional payments throughout the year.

Taking advantage of these options can reduce your mortgage balance faster and lower the amount of interest you pay over the life of your loan.
