Canadian Mortgage Terms — Plain Language Glossary

Amortization Period

The amortization period is the total length of time over which your entire mortgage balance would be repaid if you made every scheduled payment and never changed your terms. In Canada, the most common amortization periods are 25 years (required for insured mortgages) and up to 30 years for uninsured mortgages (with 20% or more down payment). A longer amortization means lower monthly payments but significantly more total interest paid over the life of the loan. For example, a $500,000 mortgage at 4.89% over 25 years costs approximately $175,000 more in total interest than the same mortgage over 20 years.

Example: You take out a $500,000 mortgage with a 5-year term. Your amortization is 25 years — so after your first 5-year term ends, you'll renew and have 20 years left on your amortization.

Blended Payment

A blended payment is the standard type of mortgage payment in Canada, where each monthly payment consists of both principal and interest combined into one fixed dollar amount. The blend shifts over time: in the early years of a mortgage, most of each payment goes toward interest with very little reducing your principal balance. As years pass and your balance shrinks, the interest portion decreases and the principal portion increases — even though your total payment amount stays the same. This gradual shift is what makes mortgage amortization work. Most Canadian mortgages use blended payments. The alternative is an interest-only payment structure, which is rare in standard residential mortgages.

Example: On a $400,000 mortgage at 4.89%, your blended monthly payment might be $2,290. In year 1, roughly $1,630 goes to interest and $660 reduces your principal. By year 20, roughly $750 goes to interest and $1,540 reduces principal.

Bridge Financing

Bridge financing is a short-term loan that covers the gap between when you must close on your new home purchase and when you receive the proceeds from selling your existing home. It literally "bridges" the two transactions. Bridge loans are typically arranged through your mortgage lender and run for days to a few months, depending on when your sale closes. They carry higher interest rates than standard mortgages — usually prime plus 2-4% — because they are short-term, unsecured by the new property, and resolved quickly. Bridge financing requires that your existing property is sold with a firm closing date. You cannot usually bridge-finance a property that hasn't sold yet.

Example: You buy a new home closing May 15th, but your existing home sale closes May 30th. You need a bridge loan for 15 days on the equity from your existing home to fund the new purchase.

Closed Mortgage

A closed mortgage is a mortgage that restricts prepayment — you can only repay it early within defined limits (the prepayment privilege) or by paying a financial penalty to break it. In exchange for accepting these restrictions, you receive a significantly lower interest rate than an open mortgage. Approximately 95% of Canadian mortgages are closed. Closed mortgages typically run for terms of 6 months to 10 years, with 5-year fixed closed being the most popular product. Most closed mortgages include some prepayment privilege — often 10-20% of the original principal per year as a lump sum payment and a payment increase allowance — which provides meaningful flexibility without requiring a full open mortgage.

CMHC Insurance (Mortgage Default Insurance)

CMHC insurance — provided by Canada Mortgage and Housing Corporation, Sagen, or Canada Guaranty — is mandatory for any Canadian mortgage where the down payment is less than 20% of the purchase price. It protects the lender (not you) if you default on your mortgage. The premium ranges from 0.60% to 4.00% of the mortgage amount depending on your down payment percentage, and it is typically added to your mortgage principal rather than paid upfront. While this insurance costs you money, it also enables you to purchase a home with as little as 5% down and generally results in lower interest rates, because insured mortgages are lower risk for lenders.

Example: On a $500,000 purchase with 10% down ($50,000), your CMHC premium is 3.10% of $450,000 = $13,950, added to your mortgage for a total of $463,950.

Co-Signer / Guarantor

A co-signer is someone who signs the mortgage alongside the primary borrower and is equally responsible for the debt. Their income can be used to qualify for a larger mortgage, making co-signing useful when the primary borrower's income alone is insufficient. A guarantor is slightly different: they guarantee the mortgage will be repaid if the primary borrower defaults, but they are not on title to the property. Co-signers appear on the title deed; guarantors typically do not. Both arrangements affect the co-signer's or guarantor's credit profile and their ability to borrow elsewhere, since lenders treat the mortgage as their obligation too.

Compound Interest (Canadian Semi-Annual)

In Canada, fixed rate mortgages are required by law to compound semi-annually — meaning interest is calculated and added to the balance twice per year, not monthly as in the United States. This makes Canadian mortgage rates slightly more favourable than they appear when compared at face value with American rates. A 4.89% rate compounding semi-annually has an effective annual rate of approximately 4.95%, while 4.89% compounding monthly would produce an effective rate of about 5.00%. Variable rate mortgages in Canada typically compound monthly. When comparing rates across mortgage products or international markets, always clarify the compounding frequency.

Conventional Mortgage

A conventional mortgage is a mortgage where the borrower has provided a down payment of at least 20% of the purchase price. Because the borrower has more equity from the start, CMHC mortgage default insurance is not required — the lender takes on the default risk directly. Conventional mortgages offer more flexibility in some ways (larger purchase prices, longer amortizations up to 30 years, easier refinancing) but the rates may be slightly higher than insured mortgages because the lender cannot pool the risk through insurance. Also called an "uninsured" mortgage.

Default

A mortgage default occurs when a borrower fails to meet the terms of their mortgage contract — most commonly by missing scheduled payments. In Canada, lenders typically classify a mortgage as in default after 3 consecutive missed payments, though the process varies by lender and province. Once a mortgage is in default, the lender has the legal right to begin foreclosure or power of sale proceedings to recover the outstanding balance by selling the property. Canadian mortgage default insurance (CMHC) exists specifically to protect lenders against losses when borrowers default — which is why it is mandatory for high-ratio mortgages. Default has severe, long-lasting consequences for credit scores and future borrowing ability.

Down Payment

The down payment is the portion of the purchase price you pay from your own funds (or approved sources) at closing, with the remainder financed by your mortgage. In Canada, the minimum down payment is 5% for homes priced up to $500,000; 5% on the first $500,000 plus 10% on the portion above $500,000 for homes priced between $500,000 and $999,999; and 20% for homes priced at $1,000,000 or more. Providing 20% or more eliminates the requirement for CMHC mortgage insurance. Approved down payment sources include personal savings, RRSP Home Buyers' Plan, FHSA, gifted funds from an immediate family member, and proceeds from a property sale.

Example: On an $800,000 home, the minimum down payment is 5% × $500,000 + 10% × $300,000 = $25,000 + $30,000 = $55,000 (6.875%).

Equity

Equity is the portion of your property that you truly own — calculated as the property's current market value minus the outstanding mortgage balance and any other liens or encumbrances. Your equity builds in two ways: through mortgage payments that reduce your principal balance, and through property value appreciation over time. Home equity is the primary wealth-building mechanism for most Canadian households. You can access equity through refinancing (borrowing more against the property), a Home Equity Line of Credit (HELOC), or selling the property. Maximum refinancing to 80% of appraised value is the standard limit for conventional mortgages.

Example: Your home is worth $900,000. Your mortgage balance is $450,000. Your equity is $450,000 — 50% of the property value.

First Home Savings Account (FHSA)

The First Home Savings Account is a registered account introduced by the Canadian federal government in 2023 for first-time homebuyers. It combines features of an RRSP and a TFSA: contributions are tax-deductible (like an RRSP), and qualifying withdrawals for a first home purchase are tax-free (like a TFSA). The annual contribution limit is $8,000, with a lifetime limit of $40,000. Unused contribution room carries forward one year. Funds can be invested and grow tax-free within the account. If not used to buy a first home within 15 years of opening, the account must be transferred to an RRSP. This account is one of the most powerful savings tools available to Canadian first-time buyers.

Fixed Rate Mortgage

A fixed rate mortgage locks your interest rate for the entire duration of your mortgage term. If you lock in at 4.89% for 5 years, your rate stays at 4.89% regardless of what happens to the Bank of Canada prime rate or bond yields during those 5 years. This provides payment certainty and protection against rising rates. The trade-off is that if rates fall significantly, you're still paying the higher locked-in rate unless you break the mortgage (paying a penalty). Fixed rate mortgages typically carry higher prepayment penalties than variable rate mortgages, particularly at major banks where the Interest Rate Differential calculation can produce very large penalty amounts.

GDS Ratio (Gross Debt Service)

The Gross Debt Service ratio measures the percentage of your gross monthly income that goes toward housing costs. It includes: your monthly mortgage payment (at the stress test rate), monthly property taxes, monthly heating costs, and 50% of monthly condo fees if applicable. The maximum GDS ratio allowed by most Canadian lenders is 39%. This rule ensures that your basic housing costs do not consume more than 39 cents of every dollar you earn before tax. If your GDS exceeds 39%, lenders will reduce the mortgage amount until your ratio falls within the limit. GDS is always calculated at the stress test rate, not your actual contract rate.

Example: Gross income $120,000/year = $10,000/month. Max GDS at 39% = $3,900/month for housing costs including mortgage, taxes, and heat.

High-Ratio Mortgage

A high-ratio mortgage is a mortgage where the down payment is less than 20% of the purchase price — meaning the loan-to-value ratio exceeds 80%. High-ratio mortgages are considered higher risk for lenders because the borrower has less equity at stake. Under Canadian law, all high-ratio mortgages must be insured through CMHC, Sagen, or Canada Guaranty, and the borrower pays the insurance premium (0.60%–4.00% of the mortgage amount). High-ratio mortgages are limited to properties with purchase prices under $1,500,000 (as of 2024) and must be amortized over a maximum of 25 years (30 years for first-time buyers purchasing new builds as of December 2024).

Home Buyers' Plan (HBP)

The Home Buyers' Plan allows first-time homebuyers in Canada to withdraw up to $60,000 from their RRSP tax-free to use as a down payment (the limit was increased from $35,000 in 2024). Couples can each withdraw $60,000 for a combined $120,000. The withdrawn amount must be repaid back into your RRSP over 15 years — starting 2 years after the year of withdrawal — or the annual repayment amount is added to your taxable income. Unlike the FHSA, HBP withdrawals are a loan to yourself that must be repaid. The HBP can be combined with the FHSA for maximum down payment flexibility.

Hypothec (Quebec)

In Quebec, the legal mechanism used to secure a mortgage against property is called a hypothec rather than a mortgage. Under Quebec civil law (as opposed to the common law system used in other Canadian provinces), a hypothec is a security interest registered against the property title. Functionally, a hypothec works like a mortgage — the lender holds security over the property and can take action if the borrower defaults. However, the legal process for enforcing a hypothec differs from mortgage enforcement in common law provinces. Homebuyers in Quebec will see the term "hypothec" on their mortgage documents rather than "mortgage."

Insured Mortgage

An insured mortgage is one where mortgage default insurance has been purchased — either because the down payment was less than 20% (mandatory) or because the lender chose to insure it for pricing reasons (insurable). The insurance is provided by CMHC, Sagen, or Canada Guaranty. Insured mortgages carry lower interest rates than uninsured mortgages because the insurance eliminates the lender's default risk. The premium (paid by the borrower) typically ranges from 0.60% to 4.00% of the mortgage amount depending on LTV. Insured mortgages must have a maximum 25-year amortization (with limited exceptions) and a purchase price below $1.5 million.

Insurable Mortgage

An insurable mortgage is one where the borrower has 20% or more down payment — so insurance is not mandatory — but the lender chooses to insure the mortgage in the background through CMHC or a private insurer. The borrower does not pay the insurance premium in this case; the lender absorbs or passes on the cost through slightly different pricing. Insurable mortgages benefit from the lower interest rates associated with insured mortgages, while being available to borrowers with 20%+ down. The key restrictions: amortization must be 25 years or less, and the property must be owner-occupied. Investment properties and refinances do not qualify as insurable.

Interest Rate Differential (IRD)

The Interest Rate Differential is the primary component of the penalty for breaking a fixed rate closed mortgage before the term ends. It is calculated as: (your contract rate minus the lender's current comparison rate for a term matching your remaining time) × outstanding balance × remaining months ÷ 12. The comparison rate used matters enormously: Big 6 banks use their inflated posted rates, producing larger penalties, while monoline lenders use their actual discounted rates, producing smaller, fairer penalties. IRD can range from a few thousand dollars to $40,000 or more depending on the lender, rate environment, and how much time remains in your term.

Example: $500,000 at 4.89%, 36 months remaining. Comparison rate 3.89%. IRD = 1.00% × $500,000 × 3 = $15,000. But bank posted-rate IRD could be dramatically different.

Land Transfer Tax

Land transfer tax (LTT) is a provincial tax paid by the buyer at the time of a property purchase, based on the purchase price. Most Canadian provinces charge LTT, with Ontario and British Columbia having the highest rates. Toronto also charges a municipal land transfer tax on top of Ontario's provincial LTT, making Toronto purchases subject to double taxation. First-time homebuyers may qualify for rebates: Ontario offers up to $4,000; BC offers up to $8,000 for properties under a certain value; Toronto offers up to $4,475. In Alberta and Saskatchewan, there is no land transfer tax — only a nominal title registration fee. LTT must be paid in cash at closing and cannot be added to the mortgage.

Example: In Toronto, a $900,000 purchase pays combined provincial + municipal LTT of approximately $30,950 — a significant closing cost to budget for.

Maturity Date

The maturity date is the date on which your current mortgage term ends and the outstanding balance legally becomes due. At maturity, you must either pay off the full balance, renew the mortgage with the same lender, or refinance with a new lender. You do not automatically need to sell your home or pay off the entire original amount — the outstanding balance at maturity is simply what remains after years of payments. Lenders typically begin contacting borrowers 120-180 days before maturity with renewal offers. Missing your maturity date results in the mortgage reverting to open status at much higher posted rates — a costly mistake to avoid.

Monoline Lender

A monoline lender is a financial institution that specializes exclusively in mortgage lending — unlike banks that offer chequing accounts, credit cards, and other financial products. Well-known Canadian monoline lenders include First National, MCAP, MERIX Financial, RMG Mortgages, and Radius Financial. Monoline lenders typically offer more competitive rates than the Big 6 banks, better prepayment privileges (20/20 vs 10/10), and more transparent IRD penalty calculations. They are federally regulated and must comply with the same OSFI rules as banks. The primary trade-off is that you must have a broker to access most monolines — they do not have retail branches.

Mortgage Broker

A mortgage broker is a licensed professional who acts as an intermediary between borrowers and multiple lenders, shopping your application across banks, credit unions, monoline lenders, and alternative lenders to find the most suitable mortgage. Brokers are regulated provincially and must be licensed in each province where they operate. In most cases, brokers are paid by the lender through a finder's fee, not by the borrower — making their services free to use. Brokers provide access to lenders and products not available at retail bank branches, and they can often negotiate better rates and terms than borrowers would obtain by walking into a branch directly.

Mortgage Discharge

A mortgage discharge is the legal process of removing a mortgage from the title of your property once it has been fully repaid. When you pay off your mortgage in full — whether through regular payments reaching zero, a lump sum payoff, or the sale of the property — your lender must formally release their claim on your property by filing a discharge with the land registry office. Lenders charge a discharge fee, typically $200–$400, for this administrative process. If you are switching lenders at renewal, the new lender typically registers a new charge while the old lender discharges — legal costs may apply and are sometimes covered by the new lender as an incentive.

Mortgage Portability

Mortgage portability is a feature that allows you to transfer your existing mortgage — including its remaining balance, rate, and term — from your current property to a new property you are purchasing. This is valuable when you want to sell your home and buy a new one without breaking your mortgage and paying a penalty. Most Canadian closed mortgages are portable, but the process is more complex than it sounds: you must still qualify for the mortgage under current rules, close on the new property within a lender-specific window (typically 30-120 days of selling), and the lender has full discretion to approve or decline the port.

Example: You have a $300,000 mortgage at 2.89% with 3 years remaining. You sell and buy a new home at $700,000. You port your $300,000 at 2.89% and top up the remaining $200,000 at current market rates — a blended rate arrangement.

Mortgage Renewal

Mortgage renewal is the process of extending your mortgage for a new term when your existing term reaches maturity. At renewal, you negotiate a new rate, choose a new term length, and your mortgage continues with the outstanding balance carried forward. You can renew with your existing lender (no stress test required since 2023) or switch to a new lender (stress test required). Most Canadians renew several times over the life of their amortization. Your lender will send a renewal offer approximately 120 days before your maturity date — this offer is almost never their best rate. Always shop the market and negotiate before signing any renewal offer.

Open Mortgage

An open mortgage allows the borrower to repay any amount — up to and including the full outstanding balance — at any time, without any prepayment penalty whatsoever. This maximum flexibility comes at a significant cost: open mortgage rates are typically 1–2 percentage points higher than equivalent closed mortgage rates. Open mortgages are usually available only in short terms (6 months or 1 year) because lenders are unwilling to offer long-term open products at these rate levels. They are most useful for borrowers who are selling their home within the near term, expecting a large windfall, or in bridge financing situations where the repayment date is unknown.

Prepayment Penalty

A prepayment penalty is the fee charged by a lender when a borrower repays more than the permitted prepayment privilege on a closed mortgage — or breaks the mortgage entirely before the term ends. For fixed rate mortgages, the penalty is the greater of three months' interest or the Interest Rate Differential (IRD). For variable rate mortgages, it is typically just three months' interest. Penalties can range from $3,000 to $40,000 or more depending on your lender type, rate, remaining term, and outstanding balance. Big 6 bank fixed rate penalties are consistently larger than monoline lender penalties due to how they calculate IRD using posted rates.

Prepayment Privilege

A prepayment privilege is the contractual right to pay down more of your mortgage principal than your regular scheduled payments — without triggering a penalty. Privileges are specified as a percentage of the original principal for lump sum payments (typically 10% or 20% per year) and as a percentage increase in your regular payment amount (typically 10–100% depending on lender). For example, a 20/20 privilege on a $400,000 original mortgage allows up to $80,000 in lump sum payments per year, plus the ability to double your regular payment amount. Prepayment privileges reset annually — often January 1st — and unused room does not carry forward.

Principal

The principal is the actual loan amount — the money your lender advanced to help purchase your property, minus any repayments made to date. When you take out a $500,000 mortgage, $500,000 is your original principal. Each payment you make includes some interest (the cost of borrowing) and some principal repayment (reducing what you owe). The principal balance is the number that matters for calculating your equity, your prepayment privilege amounts, and your mortgage statements. When mortgage professionals refer to "paying down your mortgage," they mean reducing the principal balance faster than the amortization schedule requires.

Property Transfer Tax (BC)

Property Transfer Tax (PTT) is British Columbia's version of land transfer tax, charged at closing when property ownership is transferred. The rate is 1% on the first $200,000 of fair market value, 2% on the portion from $200,001 to $2,000,000, and 3% on the portion above $2,000,000. A further 2% foreign buyer tax applies to certain foreign purchasers in specific areas. First-time buyers may qualify for a full PTT exemption on properties up to $835,000 (as of 2024) if meeting eligibility requirements. Like land transfer tax in other provinces, PTT must be paid in cash at closing and cannot be financed through the mortgage.

Rate Hold

A rate hold (also called a rate lock) is a commitment from a lender to hold a specific mortgage rate for you for a defined period — typically 90 to 120 days — while you complete your purchase. This protects you from rate increases that occur between your pre-approval and your closing date. If rates rise during your rate hold period, you get the lower locked-in rate. If rates fall, most lenders allow you to take the lower rate at closing — though this varies by lender and is worth confirming before you lock. Rate holds are typically available through pre-approval applications at no cost to you.

Refinancing

Refinancing means replacing your existing mortgage with a new one — either with the same lender or a new lender. Refinancing can occur mid-term (paying a prepayment penalty to break the existing mortgage) or at maturity (no penalty). Reasons to refinance include: accessing home equity as cash, consolidating high-interest debt, changing your amortization period, adding or removing a borrower from title, or switching to a product with better terms. Refinancing typically requires a new qualification process, including a stress test with the new lender. The maximum refinance amount is 80% of the property's appraised value.

Stress Test (Mortgage)

The mortgage stress test is a federal qualification requirement mandating that all borrowers at federally regulated lenders must prove they can afford mortgage payments at a rate higher than their actual contract rate. Specifically, borrowers must qualify at the greater of their contract rate plus 2%, or 5.25%. This was introduced by OSFI (B-20 guideline) to protect borrowers and the financial system from taking on excessive debt that would become unmanageable if rates rose after closing. The stress test reduces qualifying power by approximately 20% compared to qualifying at the actual contract rate. Renewals at the same lender are exempt; new purchases and refinances with new lenders are not.

Example: Actual rate 4.89%. Stress test rate: 6.89% (4.89% + 2%). All qualifying calculations use 6.89%.

TDS Ratio (Total Debt Service)

The Total Debt Service ratio measures the percentage of your gross monthly income that goes toward ALL debt obligations — your housing costs (GDS) plus all other monthly debt payments including car loans, credit card minimums, student loans, and other credit obligations. The maximum TDS ratio allowed by most Canadian lenders is 44%. If your car payment is $600/month, your student loan payment is $400/month, and your housing costs (GDS) total $3,200/month, your TDS includes all $4,200. On $120,000 annual income ($10,000/month), your TDS ratio would be 42% — just under the 44% limit. Like GDS, TDS is calculated at the stress test rate.

Term

The mortgage term is the length of your current mortgage contract — how long your agreed interest rate and conditions are in effect before the outstanding balance comes due for renewal or repayment. Common term lengths in Canada are 1, 2, 3, 5, and 10 years, with 5 years being by far the most popular choice. At the end of your term (maturity), you renew or refinance — the term is not the same as your amortization period, which is the total time to pay off the mortgage. Choosing a longer term provides rate certainty; shorter terms offer more flexibility to renegotiate and can be advantageous when rates are expected to fall.

Title Insurance

Title insurance protects homebuyers and lenders against losses arising from defects in the property title — including fraud, encroachments, zoning violations, survey errors, or unknown liens. In Canada, most lenders require the borrower to purchase a lender's title insurance policy as a condition of the mortgage. Homeowners should also separately purchase an owner's title insurance policy, which protects their own interest in the property (not just the lender's). Title insurance is a one-time premium paid at closing, typically $200–$400 for a lender policy and $200–$500 for an owner policy depending on property value. It covers the lender for as long as the mortgage exists and the homeowner for as long as they own the property.

Trigger Rate

The trigger rate became widely known during the 2022-2023 rate-hiking cycle. For variable rate mortgages with fixed payments, the trigger rate is the interest rate at which the full monthly payment no longer covers the interest charged — meaning no principal is being repaid and the mortgage balance is actually growing. When a borrower's rate rises above their trigger rate, lenders are required to take action: either increase the payment, require a lump sum payment, or in some cases initiate a more significant conversation about the mortgage. Many Canadian variable-rate borrowers hit their trigger rate in 2022-2023, creating significant market disruption and prompting changes to how fixed-payment variable mortgages are structured.

Example: If your original payment was set to amortize a $400,000 mortgage over 25 years at 1.75%, and your rate rises to 5.5%, your monthly payment no longer covers the interest — you've hit (and passed) your trigger rate.

Uninsured Mortgage

An uninsured mortgage is a mortgage where no mortgage default insurance (CMHC, Sagen, or Canada Guaranty) is in place — typically because the borrower provided a down payment of 20% or more. Also called a conventional mortgage. Uninsured mortgages have more flexibility in terms of purchase price (no $1.5 million cap), amortization periods (up to 30 years), and property types (investment properties, refinances). However, they typically carry slightly higher interest rates than insured mortgages because the lender bears the full default risk. The stress test applies equally to uninsured mortgages, and lenders may apply more conservative qualifying criteria for higher LTV uninsured deals.

Variable Rate Mortgage

A variable rate mortgage has an interest rate that fluctuates with the Bank of Canada's prime rate throughout the term. When the Bank of Canada raises or lowers its overnight lending rate, prime rate changes (usually by the same amount), and your mortgage rate adjusts accordingly. Variable rates are expressed as a discount or premium to prime — for example, "prime minus 0.80%". Variable rate mortgages come in two structures: adjustable rate mortgages (ARM), where your payment amount changes as rates change, keeping your principal repayment pace constant; and variable rate mortgages with fixed payments, where your payment stays the same but the split between principal and interest changes with rate movements (these carry trigger rate risk).

Example: Prime rate = 4.95%. Variable mortgage at prime minus 0.80% = 4.15% interest rate. If Bank of Canada cuts 0.25%, prime becomes 4.70% and your rate drops to 3.90%.
