Canadian Mortgage Glossary
39 essential mortgage terms explained in plain English, with Canadian-specific definitions, real examples, and what they actually mean for your mortgage decisions.
Quick Answer
Buying a home is hard enough. Understanding mortgage language should not be. Whether you are buying your first property, renewing, refinancing, or comparing lenders, this glossary covers 39 essential Canadian mortgage terms — so you can make smarter decisions and avoid expensive mistakes.
Most mortgage jargon exists to protect lenders, not to help you. Terms like "uninsurable rate" and "interest rate differential" sound designed to confuse — and they often do. That confusion costs real money.
This glossary strips away the jargon and explains every term the way a good broker would over coffee: plainly, with Canadian-specific context, and with what it actually means for your wallet.

How does your rate tier work?
Three terms in this glossary — insured, insurable, and uninsurable — determine the rate you actually get. Here is how they compare.
| Rate Tier | Down Payment | CMHC Required? | Typical Pricing |
|---|---|---|---|
| Insured | < 20% | Yes (premium added to balance) | Lowest rates available |
| Insurable | ≥ 20% | No (but meets insurer criteria) | Mid-tier pricing |
| Uninsurable | ≥ 20% | No (does not qualify) | Highest rates |
Refinances, rentals, amortizations over 25 years, and homes above $1.5M typically fall into the uninsurable tier.
Navigate by letter
- Amortization
- The total length of time it would take to fully pay off your mortgage at your scheduled pace. In Canada, 25 years is standard. Some borrowers qualify for 30 years depending on lender rules and eligibility. Stretching the amortization lowers your monthly payment today but increases the total interest you pay over time.Example: A $500,000 mortgage over 25 years means 300 monthly payments.
- Appraisal
- A professional estimate of your home's market value, ordered by the lender to confirm the property is worth what you're paying or borrowing against. Budget $300 to $500.
- Bi-Weekly Accelerated Payments
- Paying half your regular monthly payment every two weeks. Because there are 26 bi-weekly periods in a year, you effectively make one extra monthly payment annually. That one additional payment per year can cut years off your amortization without dramatically changing your budget.Example: $2,000 monthly becomes $1,000 bi-weekly, totaling $26,000 per year instead of $24,000.
- Blended Payment
- A single regular payment combining both principal and interest. Most Canadian mortgages work this way. It keeps your payment amount predictable from one month to the next.
- Bridge Financing
- A short-term loan used when you buy your next home before your current one sells. It covers the gap between the two transactions, typically for 1 to 90 days.
- Closed Mortgage
- Offers lower rates than open mortgages but limits how much you can prepay without a penalty. If you break a closed mortgage early, the penalty is usually the greater of three months' interest or the IRD. The cheapest rate is not always the cheapest mortgage.
- CMHC Insurance
- Mortgage default insurance required when your down payment is below 20%. Three providers offer this in Canada: CMHC, Sagen, and Canada Guaranty. This insurance protects the lender, not you. The premium gets added to your mortgage balance.See CMHC premium tiers
- Conventional Mortgage
- A mortgage where your down payment is 20% or more. No default insurance required, which reduces upfront borrowing costs. That said, a larger down payment does not guarantee a lower rate.
- Cost of Borrowing
- The true total you pay for your mortgage: interest, applicable fees, and any insurance premiums. Most borrowers compare rates and ignore this number. That habit is expensive. Most of the time a slightly higher rate with better structure costs less overall than a lower rate with poor terms.Understand your cost of borrowing
- Cost of Credit
- Often used interchangeably with cost of borrowing. It reflects the real total cost of your mortgage over time. Focus on this vs the mortgage interest rate. It is more powerful.Calculate your cost of credit
- Debt Service Ratios (GDS / TDS)
- Two affordability calculations lenders use to determine how much you can qualify for. GDS = housing costs divided by gross income. TDS = housing costs plus all other debts divided by gross income.
- Down Payment
- The portion of the purchase price you contribute upfront. Minimum requirements in Canada vary based on the home's price. A larger down payment typically reduces insurance costs and improves borrowing flexibility.Full down payment rules
- Effective Rate
- Canadian fixed mortgages compound semi-annually, not monthly. The effective rate reflects what that compounding actually costs you. The advertised rate and the effective rate are not always the same number.
- Equity
- The difference between your home's value and your remaining mortgage balance. As your balance drops or your home appreciates, your equity grows.
- FHSA (First Home Savings Account)
- A registered account built for first-time buyers. Contributions are tax-deductible. Qualifying withdrawals are tax-free. If you haven't opened one and you're buying your first home, it belongs in your plan.FHSA details
- Fixed Rate
- Your rate stays the same for the full mortgage term. Payments are predictable. Whether a fixed rate is the right choice depends on your timeline, flexibility needs, and overall strategy, not just the number on the rate sheet.How rates are set
- High-Ratio Mortgage
- A mortgage with less than 20% down. Default insurance is required. Because the lender's risk is backed by insurance, high-ratio mortgages often qualify for competitive pricing.
- Home Buyers' Plan (HBP)
- Allows eligible buyers to withdraw from their RRSP to help fund a purchase. Repayment rules apply. When used thoughtfully as part of a larger strategy, it can meaningfully improve your position.HBP guide
- Insurable Rate
- A pricing category for mortgages that meet insurer guidelines, even though insurance was not purchased. Typically priced between insured and uninsurable rates.Compare insurable rates
- Insured Rate
- Usually the lowest rate tier available. Applies to default-insured mortgages where the down payment is under 20%.Compare insured rates
- IRD (Interest Rate Differential)
- A penalty calculation used when you break a fixed-rate mortgage before the term ends. This is where borrowers regularly get blindsided. On a typical mortgage, IRD penalties can exceed $10,000. Always ask your lender to calculate your penalty exposure before you sign.IRD explained
- Land Transfer Tax (LTT)
- A tax paid when purchasing real estate. Rules and amounts vary by province. Ontario uses a bracket-based structure. Toronto adds a second municipal layer on top.Calculate your LTT
- Loan-to-Value (LTV)
- Your mortgage balance divided by your property's value. LTV affects your rate, approval conditions, and whether default insurance applies.Example: $480,000 mortgage on a $600,000 home equals 80% LTV.
- Maturity Date
- The date your mortgage term ends. At maturity, you renew, switch lenders, refinance, or repay the balance. Most borrowers underestimate how much negotiating leverage they hold at this moment.
- Monoline Lender
- A lender whose focus is primarily mortgages rather than full banking products. Often accessed through brokers, and frequently competitive on both rates and terms.
- Mortgage Broker
- A licensed professional who compares options across multiple lenders, rather than offering one institution's product line. That access creates better options and real negotiating leverage for many borrowers.
- Mortgage Qualifying Rate (MQR)
- The benchmark used to stress test whether you can afford the mortgage you're applying for. Borrowers must qualify at the required benchmark or their contract rate plus the applicable buffer, whichever is higher.Stress test guide
- Open Mortgage
- Can usually be paid off at any time without penalty. Useful if you expect to sell, refinance, or receive a large sum in the near term. Rates are typically higher than closed mortgages.
- OSFI
- The Office of the Superintendent of Financial Institutions. Canada's federal banking regulator. Responsible for mortgage guidelines, including stress test policy.B-20 guide
- Porting
- Transferring your existing mortgage to a new property when you move. It can help you avoid penalties, but approval is not automatic, and the conditions are more involved than most people expect.
- Pre-Approval
- A conditional approval from a lender based on your income, credit, and debts, often with a rate hold for a limited period. More reliable than estimating your own budget, but not the same as a final approval.
- Prepayment Privileges
- Your contractual right to make extra payments, whether as lump sums or increased regular payments, without a penalty. These payments typically reduce your principal directly, which makes this one of the most practically valuable features in a mortgage. Not all lenders offer the same terms.
- Prime Rate
- The benchmark rate used by lenders for variable mortgages and lines of credit. Variable pricing is expressed as Prime plus or minus a spread.Example: Variable rate of Prime - 0.50% means if Prime is 5.95%, your rate is 5.45%.How Prime is set
- Refinancing
- Replacing your current mortgage with a new one, typically to access equity, consolidate debt, or adjust your terms. It may trigger penalties and requires re-qualifying under current rules.Refinance vs renewal
- Renewal
- When your term ends and you negotiate new conditions. Many borrowers sign the first offer their lender sends without questioning it. Renewal is one of the strongest opportunities you have to reduce your total borrowing cost. Most people leave money on the table here.Renewal guide
- Semi-Annual Compounding
- The standard compounding method for fixed-rate mortgages in Canada. Interest is calculated twice per year. It is a technical detail that affects your real borrowing cost more than most people realize.Example: A 4.99% posted rate compounds to an effective monthly rate of approximately 0.4116%.
- Term
- How long your current mortgage contract lasts, typically one to five years. Not the same as amortization. Term = contract length. Amortization = full payoff timeline.
- Uninsurable Rate
- The pricing category for mortgages that do not qualify under insurer guidelines. Examples include refinances, rental properties, longer amortizations, and higher-value homes. These mortgages are typically priced above insured tiers.Compare uninsurable rates
- Variable Rate
- A rate that moves with Prime. Depending on how your mortgage is structured, your payment may stay fixed while the interest portion adjusts, or the payment itself may change. Variable rates can work well for borrowers who are comfortable with some movement and focused on keeping flexibility.BoC rate impact

Rate vs. cost — they are not the same thing
Most borrowers focus on getting the lowest rate. But the real question is: what does this mortgage cost over time? A slightly higher rate with better prepayment privileges, lower penalties, and flexible terms often costs less than the lowest rate with rigid conditions. See how to compare the real cost.

IRD penalties can cost you $10,000+
Breaking a fixed-rate mortgage early triggers an Interest Rate Differential penalty — and borrowers are regularly blindsided by the amount. Before you sign any mortgage, ask your lender to show you the penalty calculation. Better yet, ask a broker to compare penalty structures across lenders. Learn how IRD is calculated.

Your renewal is your biggest leverage moment
When your term ends, you do not have to accept your lender's first offer. In fact, most renewal offers are not the best rate available. Shop around, get competing quotes, and let lenders compete for your business. Even a 0.15% difference on a $500,000 mortgage saves over $4,000 in five years.
