Canadian Mortgage Terms Explained: The Complete 2026 Glossary

You're at the kitchen table with a mortgage document, and someone just used a term you don't recognize. You nod like you do. Later you search it and find a definition that uses four more terms you don't know.

Canadian mortgage jargon is its own dialect. And unlike the US version you've seen online, our rules are genuinely different: different insurance requirements, different stress test mechanics, different lender incentives around things like collateral charges and IRD penalties.

This glossary covers 23 terms that come up repeatedly in real files. Not every term that exists. The ones that actually affect what you pay, whether you qualify, and whether you're locked in longer than you need to be.

High-Ratio Mortgage 1,300 searches/mo

A high-ratio mortgage is one where the down payment is less than 20% of the purchase price. The loan-to-value (LTV) ratio exceeds 80%, which the federal government classifies as higher-risk lending.

All high-ratio mortgages in Canada require mortgage default insurance from one of three providers: CMHC (government-backed), Sagen, or Canada Guaranty. The insurance protects the lender, not the borrower, but you pay the premium.

Insurance premiums by down payment size:

• 5% down: 4.00% of the loan amount added to your mortgage
• 10% down: 3.10% of the loan amount
• 15% down: 2.80% of the loan amount

On a $700,000 purchase with 5% down ($35,000), the loan is $665,000 and the CMHC premium is $26,600, making the total insured mortgage $691,600. That premium also has provincial sales tax applied at closing in Ontario (8% = $2,128 paid upfront, not added to the mortgage).

High-ratio mortgages have one advantage over conventional: insured mortgages typically receive lower rates than uninsured ones, because the lender carries less default risk. The rate savings can partially offset the insurance cost over a full amortization.

Note: Properties priced over $1,500,000 are not eligible for insured (high-ratio) mortgages as of 2024 rules. A 20% minimum down payment is required on any purchase above that threshold.

Conventional Mortgage

A conventional mortgage is one where the down payment is 20% or more. No mortgage default insurance is required. The LTV is 80% or below.

Conventional mortgages can be used on properties over $1,500,000, investment properties, and any situation where the buyer has sufficient equity or down payment to skip insurance. The trade-off: conventional (uninsured) mortgages typically carry slightly higher rates than insured mortgages because the lender takes on more default risk without the government backstop.

The rate premium for uninsured vs insured is usually 0.10% to 0.25%, which can add up over 25 years but is still less than paying the insurance premium in most scenarios where buyers have the 20% available.

Open vs Closed Mortgage

This distinction matters more than most people think, and most first-time buyers default to closed without realizing what they're giving up or gaining.

Closed mortgage: Has restrictions on prepayment. Breaking the mortgage before term end triggers a penalty. Most Canadian residential mortgages are closed. In exchange for this restriction, closed mortgages offer lower rates than open mortgages.

Open mortgage: Can be repaid, renegotiated, or refinanced at any time without penalty. Open mortgages carry higher rates, typically 0.50% to 1.50% above comparable closed terms, to compensate the lender for the prepayment flexibility.

Open mortgages make sense if you're expecting to sell the home, receive an inheritance, or know you'll want to refinance within 6 to 12 months. For most buyers who plan to stay put for the full term, a closed mortgage with good prepayment privileges is the better choice.

Amortization Period

The amortization period is the total length of time to fully pay off the mortgage, assuming consistent payments and interest rate. It is not the same as the mortgage term.

Standard amortization in Canada is 25 years for insured mortgages. Since August 2024, 30-year amortizations are available on insured mortgages for new construction purchases, and for first-time buyers purchasing any property, under federal changes designed to improve affordability.

Uninsured (conventional) mortgages can have amortizations up to 30 years through federally regulated lenders, and sometimes longer through credit unions or private lenders.

The practical impact: On a $600,000 mortgage at 4.79%, extending from 25 to 30 years reduces the monthly payment by roughly $260 but adds approximately $88,000 in total interest over the life of the loan.

Mortgage Term

The mortgage term is the length of the current agreement with your lender, typically 1 to 5 years in Canada. At the end of the term, you renew, refinance, or pay the remaining balance in full.

The term and the amortization period are entirely different things. A 5-year term on a 25-year amortization means your rate and conditions are locked for 5 years, after which the remaining 20 years of payments must be renegotiated.

Most Canadians choose 5-year fixed terms because lenders offer competitive rates and the certainty is appealing. But 3-year fixed and variable terms can outperform over full amortization periods depending on rate movements. The choice is a forecast, not a formula.

Mortgage Maturity Date 700 searches/mo

The mortgage maturity date is the last day of the current mortgage term. On this date, the outstanding balance becomes due. Most borrowers don't pay the full balance in cash; they renew, refinance, or switch lenders.

Lenders are required to send renewal offers at least 21 days before maturity under federal rules, but many send them 120 days out. That 120-day window is intentional. The first offer in the envelope is usually not the best rate the lender will give. It's a test to see if you'll accept without negotiating.

The most important thing to know about your maturity date: you have a decision point. You can stay with your lender at a negotiated rate, switch to a new lender for better terms, or refinance to access equity. Each choice has different implications for penalties, legal costs, and your next 1 to 5 years.

Lender timing note: many banks send the renewal offer 120-150 days before maturity with a rate that's 0.20%-0.40% above what they'll actually do. The rate improves when you call and say you're comparing options.

Prepayment Privilege

The prepayment privilege is the right to make extra payments toward the mortgage principal without triggering a penalty. Most closed Canadian mortgages include a prepayment allowance of 10% to 20% of the original principal per calendar year, plus the ability to increase regular payments by 10% to 100%.

Using prepayment privileges is one of the most efficient ways to reduce total interest paid and shorten the amortization. An extra $500/month on a $600,000 mortgage at 4.79% cuts roughly 4 years off the amortization and saves approximately $65,000 in interest.

Not all mortgages have the same prepayment terms. Some "no-frills" or restricted mortgages offer lower rates in exchange for no prepayment privileges. Read the commitment letter carefully before signing.

Interest Rate Differential (IRD)

The IRD is a prepayment penalty used by most lenders when you break a fixed-rate closed mortgage before the term ends. It's the more expensive of two common penalty methods, the other being three months' interest.

The formula: (your original rate minus the lender's current rate for the remaining term) times the outstanding balance times the months remaining.

The reason Big-Five IRD penalties run 3 to 5 times higher than monoline penalties is that banks calculate the IRD using their posted rate rather than the actual discounted rate you received. A bank might give you a rate of 4.49% when their posted 5-year rate was 6.79%, meaning the "discount" was 2.30%. When you break the mortgage, that 2.30% discount gets baked back in as a larger differential, dramatically inflating the penalty.

Monolines (lenders who operate exclusively through brokers) typically use the actual contract rate in their IRD calculation. The same scenario at a monoline produces a penalty of $3,000-$5,000 versus $18,000-$28,000 at a Big Five bank. This is the central finding of the lender fairness comparison we published earlier this year.

Blend and Extend

Blend and extend is an option some lenders offer that avoids a full breakage penalty. The lender blends your existing rate with their current rate for a new term, producing a weighted average rate that's higher than today's market rate but lower than your current rate if current rates are below your locked rate.

Whether blend-and-extend saves money versus fully breaking the mortgage depends on two numbers: the blended rate you're offered versus the best rate available in the market for a new term. If the market rate is substantially lower than the blended rate, breaking and refinancing with the penalty absorbed up front often costs less over the new term.

Blend-and-extend is typically only worth it when the rate difference between your old and new mortgage is small, or when your penalty is very high. Run the numbers both ways before agreeing.

HELOC (Home Equity Line of Credit) 260 searches/mo

A HELOC is a revolving credit line secured against your home equity. It works like a credit card: you draw funds, pay them back, and draw again up to the limit. Interest is charged only on what you use.

Borrowing limits: A standalone HELOC can go up to 65% of the home's appraised value. When combined with a mortgage, the total combined debt (mortgage plus HELOC) cannot exceed 80% of the home's value. So on a $900,000 home with a $600,000 mortgage (66.7% LTV), no HELOC is available yet. At $540,000 owing (60% LTV), you could access up to $180,000 in HELOC room.

HELOCs carry variable rates, typically prime plus 0.50% to prime plus 1.00%. As of May 2026, with prime at 4.45%, that's 4.95% to 5.45%. Interest-only payments are the minimum required. Many borrowers treat HELOCs as emergency funds or home renovation financing, which is reasonable. Using a HELOC to fund lifestyle spending at 5%+ interest is less so.

HELOCs are typically attached to the property as a collateral charge. Refinancing or switching lenders later may require legal costs to remove and re-register.

Collateral Charge Mortgage 170 searches/mo

A standard charge mortgage registers the actual loan amount on title. A collateral charge registers for more than the loan, sometimes up to 125% of the home's appraised value. TD Canada Trust and some other lenders register all their mortgages as collateral charges.

The benefit to you: a collateral charge can be re-advanced later (used like a HELOC for future borrowing) without legal fees, as long as you stay with the same lender. The drawback: a collateral charge cannot be transferred to a new lender at renewal without a lawyer discharging the old charge and registering a new one, typically costing $700 to $1,500.

This legal cost is one reason collateral-charge borrowers tend to stay with their existing lender at renewal even when better rates are available elsewhere. It's by design. Knowing your charge type matters when you're planning a lender switch.

Vendor Take Back (VTB) Mortgage 260 searches/mo

A VTB mortgage is when the property seller acts as the lender for some or all of the purchase financing. Instead of receiving the full sale price at closing, the seller accepts a mortgage from the buyer, who makes payments to the seller over the agreed term.

VTBs come up most often in commercial real estate, rural properties, or situations where conventional financing is difficult to arrange. They can also help buyers who are close to qualifying but need to bridge a gap. A common structure: buyer gets a bank first mortgage at 75% LTV, then a seller VTB for an additional 10%, reducing the required down payment from 25% to 15%.

Sellers agreeing to a VTB are taking on the credit risk of the buyer. Buyers using a VTB should understand they will still need to qualify for the bank portion, and that the VTB is typically at above-market rates. Both parties should use legal counsel when structuring a VTB.

Mortgage Portability 310 searches/mo

Portability lets you move your existing mortgage, with its current rate and terms, from your old home to your new one when you sell and buy simultaneously. No prepayment penalty is triggered because the mortgage isn't being broken, just transferred.

Portability is most valuable when your current rate is below today's market rates. If you locked in at 2.49% three years ago and current 5-year rates are 4.79%, porting that rate to a new property saves real money.

Most lenders allow 30 to 120 days to complete the port. Fixed-rate mortgages are almost always portable. Variable-rate mortgages typically are not. There's usually a catch: if your new home costs more than the old one, the additional amount above the ported mortgage must be borrowed at current market rates and blended in.

Check your mortgage commitment for the portability window and the terms before listing your home for sale. A 60-day gap between sale and purchase with a 30-day portability window means you'd lose the rate protection.

Mortgage Discharge and Discharge Fee

When a mortgage is paid in full or switched to a new lender, the lender must be removed from the property's title. That process is called a discharge. The lender files the discharge documents with the land registry office, releasing their claim on the property.

In Ontario, most lenders charge a discharge fee of $200 to $400 for processing. The discharge typically takes 3 to 8 weeks after payout. If you're switching lenders at renewal, the new lender usually covers your discharge fee as part of the switch incentive.

Collateral charge mortgages require a lawyer to handle the discharge, which costs significantly more ($700 to $1,500 in legal fees on top of the discharge fee). This is one reason collateral charge borrowers face higher switching costs.

Mortgage Statement

Your mortgage statement is a periodic document from the lender summarizing: outstanding balance, payments made, the principal versus interest split, and how much prepayment room remains in the current year.

Review your annual statement specifically for two things. First, confirm your prepayment contributions were applied correctly (I've seen errors where lump sums were applied as regular payments rather than directly to principal). Second, check how much prepayment room you have left before year-end if you're planning extra payments.

Most lenders make these available online now. Annual paper statements are still sent to the address of record. Keeping your contact information current ensures you don't miss renewal offers or rate change notices.

Posted Rate

The posted rate is the rate a bank publishes publicly on its website. Nobody actually pays it. It's the anchor point from which the discount is calculated, and it exists primarily to make the "discount" look larger and to inflate IRD penalty calculations.

The reason banks maintain posted rates: when you break a mortgage, the IRD penalty is calculated as the difference between your original posted rate (not your discounted rate) and the current posted rate for the remaining term. The larger the original discount you received, the larger the penalty when you break. A borrower who received a 2.30% discount off posted has a much larger IRD denominator than a borrower at a monoline who received no posted-rate markup at all.

Understanding posted rates is mostly useful when you're comparing the penalty exposure at Big Five banks versus monoline lenders.

Trigger Rate

Trigger rate applies to variable-rate mortgages with fixed payment amounts. Most variable-rate mortgages in Canada have a fixed payment that doesn't change when the Bank of Canada adjusts rates. Instead, the split between interest and principal within that payment shifts.

When rates rise enough that the interest portion equals the entire fixed payment, the mortgage hits its trigger rate. At that point, the payment no longer covers any principal: the balance is no longer shrinking. If rates continue rising past the trigger rate, the outstanding balance can actually increase, a situation called negative amortization.

This happened to a significant number of Canadian borrowers in 2022 and 2023 as the Bank of Canada raised rates from 0.25% to 5.00% in 18 months. Lenders typically contact borrowers to request a lump-sum payment or an increase to regular payments to get the mortgage back on track.

Variable-rate mortgages with adjustable payments (where the payment itself changes with prime) do not have a trigger rate, because the payment always covers at minimum the interest owing.

Halal Mortgage

A halal mortgage is structured to comply with Islamic finance principles, which prohibit interest (riba). Because a standard mortgage charges interest, observant Muslim homebuyers often seek alternatives structured on different principles.

The most common halal mortgage structures in Canada are diminishing musharakah (co-ownership that decreases as the buyer makes payments to acquire the lender's share), ijara (lease-to-own), and murabaha (the lender buys the property and resells it to the borrower at a higher price, with the markup replacing interest). The cost of financing is embedded in the price or lease structure rather than charged as explicit interest.

In Canada, lenders offering halal-compliant products include Manzil, Eqraz, and a few credit unions. The market is growing, particularly in the GTA where a significant Muslim population has been underserved by conventional options. Halal financing typically runs 0.25% to 0.75% above comparable conventional rates when expressed in equivalent terms.

Blanket Mortgage

A blanket mortgage is a single mortgage registered against multiple properties. Real estate investors use them to finance a portfolio of properties under one loan structure rather than holding separate mortgages on each.

The advantage: one set of terms, one renewal date, potentially a lower rate due to the aggregate loan size. The complexity: selling one property in the portfolio requires either paying down the portion allocated to that property (a partial discharge) or refinancing the whole structure.

Most residential blanket mortgages are arranged through private lenders or MICs. Institutional lenders (banks, monolines) typically prefer individual mortgages per property for residential portfolios.

Mortgage Investment Corporation (MIC)

A MIC is a Canadian investment vehicle that pools capital from investors to fund mortgages, primarily to borrowers who don't qualify for A-lender (bank) financing. From the borrower's perspective, a MIC is an alternative (B or private) lender offering mortgage financing at higher rates and fees than the banks.

MICs are regulated under the Income Tax Act and must distribute at least 100% of net income to shareholders, which is why they can offer investors reasonable yields. MIC mortgages typically run 8% to 14% annual interest, feature shorter terms (6 months to 2 years), and are used as bridge financing, to recover from credit events, or for properties banks won't fund.

The goal for most MIC borrowers is to use the MIC mortgage for 12 to 24 months, improve their qualifying profile (pay down other debt, build credit history, declare more income), then refinance into an A-lender product at normal rates.

Mortgage Stress Test

The stress test is OSFI's B-20 guideline requiring borrowers to qualify at the higher of 5.25% or their actual contract rate plus 2.00%, regardless of the rate they'll actually pay. A borrower getting a 4.79% rate must prove they could handle a 6.79% rate.

The stress test applies at all federally regulated lenders. Switching lenders at renewal triggers a new stress test at the new lender. Renewing with your existing lender does not require re-qualifying.

For a detailed breakdown of how the stress test affects your purchasing power and renewal options, see the full stress test guide.

Mortgage Agent vs Mortgage Broker

In Ontario, both mortgage agents and mortgage brokers are licensed by FSRA and required to act in your best interest. The practical distinction is mostly regulatory.

A mortgage agent must operate under a licensed brokerage. A mortgage broker holds a higher FSRA licence and can operate independently or run their own brokerage. From a client's perspective, you are primarily dealing with the individual, not the brokerage, and both agents and brokers shop multiple lenders on your behalf.

The terms "mortgage broker" and "mortgage agent" are often used interchangeably in conversation, which is part of why the question gets searched frequently. If you're checking credentials in Ontario, FSRA's public registry at fsrao.ca shows the licence type and whether it's in good standing.

I am a Mortgage Agent Level 1 (FSRA #M22002086), operating under Tango Financial Inc. (FSRA #13691). The brokerage relationship means my files are supervised, which is a quality control mechanism, not a limitation.

Renewing vs Refinancing a Mortgage

Renewal means starting a new term at a new rate when your current term expires. No new money, no change in amortization, no legal work (in most cases). Just a new rate agreement for the next 1 to 5 years.

Refinancing means replacing the existing mortgage with a new, larger mortgage to access equity, change the amortization, consolidate debt, or achieve other financial goals. Refinancing always involves a payout of the existing mortgage (usually a penalty if mid-term) and typically requires legal work ($800 to $2,000).

The question of which to choose at maturity depends on whether you need new capital, have significant rate savings available, or want to restructure the debt. The full renew vs refinance guide covers when each makes sense with real numbers.

Frequently Asked Questions

What is the difference between a high-ratio and conventional mortgage?

A high-ratio mortgage has a down payment below 20% and requires mortgage default insurance. A conventional mortgage has a down payment of 20% or more and does not require insurance. High-ratio mortgages typically receive lower rates because the insurance reduces lender risk; conventional mortgages are available for higher-priced properties and have no purchase price cap.

What happens on my mortgage maturity date?

Your outstanding balance becomes due. In practice, most borrowers renew with their existing lender or switch to a new lender for better terms. Lenders send renewal offers 21 to 120 days before maturity. The first offer is rarely their best rate. Shopping the market 90 to 120 days before your maturity date gives you time to compare and negotiate.

Can I port my mortgage to a new home?

If your current mortgage is portable and you complete the move within the lender's portability window (usually 30 to 120 days), yes. Fixed-rate mortgages are generally portable; variable-rate mortgages often are not. If the new home costs more than the old one, the additional amount must be financed at current market rates and blended with the ported rate.

Why is a collateral charge harder to switch at renewal?

A collateral charge is registered on title for more than the actual mortgage amount and cannot simply be transferred to a new lender. Switching requires a lawyer to discharge the old registration and register a new one, costing $700 to $1,500. Standard charge mortgages can often be switched via a lender-to-lender assignment, with legal costs covered by the new lender as a switch incentive.

What is the IRD penalty and why is it higher at big banks?

The IRD (Interest Rate Differential) is a prepayment penalty for breaking a fixed-rate mortgage. Big banks calculate it using their posted rate rather than the actual rate you received, which inflates the penalty significantly. A borrower who received a large discount off posted rate pays a larger IRD than the same borrower at a monoline lender who received no posted-rate markup. The same $600K mortgage can cost $4,200 to break at a monoline vs $25,800 at a Big Five bank.

What is the trigger rate on a variable mortgage?

It's the interest rate at which your fixed variable-rate payment no longer covers the interest owing. At that point your mortgage balance starts growing rather than shrinking. Most variable-rate mortgages with fixed payments have a trigger rate embedded in their structure. Ask your lender what your trigger rate is when you take out a variable-rate mortgage with a fixed payment.

Is a HELOC the same as a second mortgage?

No. A HELOC is a revolving credit line secured by your home, registered as a first or second charge. A second mortgage is a separate mortgage loan registered behind the first mortgage on title, typically used to access equity without refinancing the first mortgage. Both use home equity as collateral, but their structure, rates, and registration differ. HELOCs have variable rates; second mortgages typically have fixed rates and a defined repayment schedule.

What is a VTB mortgage in Canada?

A vendor take back (VTB) mortgage is financing provided by the seller of a property to the buyer. Rather than receiving the full purchase price at closing, the seller accepts a mortgage. The buyer makes payments to the seller under the agreed terms. VTBs are more common in commercial transactions and can help buyers bridge a financing gap.

One thing I'd want my sister to know

If I had to pick one term from this list that costs the most money when people don't understand it, it's the IRD penalty. Specifically, the difference between how a Big Five bank calculates it versus how a monoline does.

Most people who are mid-term and considering a break don't know to ask "what's your IRD calculation method?" They assume the penalty is the penalty. It's not. Two lenders with the same rate and the same remaining balance can produce penalties that differ by $15,000 to $20,000 because of this one structural difference.

If you're currently with a Big Five bank and thinking about breaking your mortgage, get the payout statement in writing first. Then run the math on what you'd save at a lower market rate. The answer sometimes surprises people in the right direction, and sometimes it closes the case for staying put until maturity.

Either way, you need the actual number, not the assumption.
