Stepping into the world of mortgages can feel like learning a new language. You're immediately hit with a flood of acronyms and confusing jargon—LTV, GDS, TDS, amortization, term, collateral charge. It can make anyone's head spin and leave you feeling overwhelmed and uncertain.

This confusing language can make homeowners feel powerless. It can stop you from asking the right questions and prevent you from fully understanding the single biggest financial commitment of your life. But it doesn't have to be this way.

This guide will serve as your simple, plain-English dictionary for the most common mortgage terms used in Canada. We will translate the industry jargon into clear definitions and relatable examples, empowering you to navigate your next mortgage conversation with confidence and control.

The Core Concepts: Term vs. Amortization

These are the two most fundamental and most commonly confused terms in the mortgage world. Understanding their difference is the key to understanding your entire loan structure.

Amortization Period

Definition: The amortization period is the total length of time it will take to pay off your entire mortgage loan to a balance of zero.

The Analogy: Think of your mortgage as a marathon. The amortization is the full 25-year length of that marathon. Every single payment you make is a step towards that finish line, 25 years in the future. While some lenders may offer 30-year amortizations, 25 years is the standard for most new mortgages in Canada. A longer amortization results in lower monthly payments, but you will pay significantly more in interest over the life of the loan.

Mortgage Term

Definition: The mortgage term is the length of time that your current mortgage contract—including your interest rate, lender, and all associated conditions—is in effect.

The Analogy: If the amortization is the full 25-year marathon, your mortgage term is a single 5-year lap within that race. You commit to a specific lender and rate for that 5-year period. At the end of the term, your mortgage "matures," and you must renew your contract for another term. You will repeat this process, signing up for new terms, until you have completed the full 25-year amortization marathon.

Why the Difference Matters

It’s crucial to know the difference. Your amortization sets the overall lifespan of your debt, while your term is your short-term commitment to a specific lender and interest rate.

The Money Terms: Rates and Payments

These terms directly affect your wallet and the cost of your loan.

Fixed Interest Rate

A fixed interest rate is locked in and will not change for the entire duration of your mortgage term. If you sign up for a 5-year fixed rate at 4.99%, your principal and interest payment will remain exactly the same for all 60 of those months. This provides predictability and stability, protecting you from any potential increases in market interest rates.

Variable Interest Rate

A variable interest rate is not locked in; it fluctuates with the lender's prime lending rate, which is influenced by the Bank of Canada. If the prime rate goes up, your interest rate goes up. There are two main types:

Adjustable-Rate Mortgage (ARM): Your interest rate changes and your monthly payment adjusts accordingly.

Variable-Rate Mortgage (VRM) with Fixed Payments: Your monthly payment stays the same, but the amount that goes towards principal versus interest changes. If rates go up, more of your payment goes to interest and less to principal.

Annual Percentage Rate (APR)

The APR represents the true, annualized cost of borrowing. It includes not just the interest rate but also most of the associated fees that may be required to get the mortgage. The APR is often slightly higher than the advertised interest rate and provides a more "apples-to-apples" way to compare the total cost of different loan offers.

Prepayment Privileges

These are clauses in your mortgage contract that allow you to pay your mortgage down faster without incurring a Prepayment Penalty. Most closed mortgages in Canada offer some form of prepayment privileges, typically including:

Lump-Sum Payments: The ability to pay a large, extra amount (e.g., up to 20% of the original balance) against your principal each year.

Payment Increases: The ability to increase your regular monthly payment by a certain percentage (e.g., up to 20%) each year.

The Qualification Terms: How Lenders See You

These are the metrics lenders use to decide if you are a good candidate for a loan.

Debt Service Ratios (GDS & TDS)

These ratios are a financial stress test that all lenders use to assess your ability to handle your debts.

Gross Debt Service (GDS): This is the percentage of your gross (pre-tax) household income that is needed to cover your core housing costs. These costs include your mortgage principal and interest, property taxes, heating expenses, and 50% of any applicable condo fees (PITH). For most 'A' lenders, your GDS ratio must be below 39%.

Total Debt Service (TDS): This is the percentage of your gross income needed to cover your housing costs (PITH) plus all of your other monthly debt obligations, such as car loans, student loans, and credit card payments. For most 'A' lenders, your TDS ratio must be below 44%.

Loan-to-Value (LTV)

This is the ratio of your mortgage loan amount compared to the appraised value or purchase price of the property. For example, if you have a $400,000 mortgage on a home appraised at $500,000, your LTV is 80% ($400,000 ÷ $500,000). A lower LTV represents lower risk for the lender, as you have more equity in the home.

Credit Score (Beacon Score)

Your credit score is a three-digit number that summarizes your entire credit history and predicts your likelihood of repaying your debts. In Canada, your score is calculated by two main credit bureaus, Equifax and TransUnion, and is often called a "Beacon Score." A higher score indicates a lower risk and gives you access to the best lenders and interest rates.

Other Key Terms from A to Z

Appraisal: A formal, professional opinion of a property's market value, prepared by a licensed appraiser. Lenders require this to ensure they are not lending more money than a property is worth.

Closing Costs: The various fees you must pay on closing day to complete the purchase of a home. These include legal fees, land transfer tax, and other disbursements.

Collateral Charge: A type of mortgage registration that allows a lender to secure both a mortgage and a line of credit against your property at the same time. It can make it more difficult to switch lenders at renewal.

Conventional vs. High-Ratio Mortgage: A conventional mortgage is one where you have a down payment of 20% or more. A high-ratio mortgage is one where your down payment is less than 20% and requires mortgage default insurance.

Lender: The financial institution (bank, credit union, trust company, etc.) that is providing the mortgage funds.

Mortgage Broker: A licensed professional who acts as an intermediary, connecting borrowers with a wide variety of lenders to find the best mortgage product and rate for their specific needs.

Portability: A feature that allows you to "port" or move your existing mortgage contract and interest rate from the home you are selling to a new home you are buying.

Title Insurance: An insurance policy that protects both you and the lender from losses related to issues with the property's title or ownership.
