Mortgage Renewal Glossary — Canadian Mortgage Terms Explained
Updated March 2026 · Your complete reference for Canadian mortgage vocabulary
Mortgage renewals come with a lot of jargon — and when your lender's renewal offer arrives in the mail, you shouldn't have to guess what any of it means. This glossary defines over 40 Canadian mortgage terms in plain English, with specific context for renewal situations. Use the jump links to navigate by letter.
A
Amortization
The total length of time over which your mortgage is scheduled to be fully repaid through regular payments. In Canada, the standard amortization for insured mortgages (less than 20% down) is 25 years; for uninsured mortgages it can extend to 30 years. Important at renewal: your amortization is not reset — it continues counting down. If you took a 25-year amortization and are renewing after a 5-year term, you have approximately 20 years of amortization remaining.
ARM (Adjustable Rate Mortgage)
A type of variable rate mortgage where your actual payment amount adjusts whenever the Bank of Canada changes its overnight rate (which flows through to your lender's prime rate). When rates fall, your payment decreases; when rates rise, your payment increases. Contrast with VRM, where the payment stays constant but the interest/principal split changes. ARMs are offered by most major Canadian banks including RBC, BMO, and Scotiabank.
Assignment
The legal transfer of your mortgage from one lender to another without discharging and re-registering the charge on title. Only possible with standard charge mortgages. Collateral charges cannot be assigned — they must be fully discharged first. An assignment is the mechanism behind a "straight switch" at renewal, making it fast and low-cost.
B
B-Lender
Alternative or "near-prime" lenders that serve borrowers who don't qualify for A-lender (prime) mortgages — often due to credit challenges, self-employment income, or high debt ratios. B-lenders include Home Trust, Equitable Bank, Haventree Bank, and Bridgewater Bank. They typically charge rates 0.50–2.00% higher than A-lenders and may charge a lender fee of 0.50–1.00% of the mortgage amount. At renewal, borrowers who improve their credit profile can often graduate from a B-lender back to an A-lender.
Blended Rate
A blended rate arises when a lender offers to combine your existing below-market mortgage rate with the current market rate to create a single averaged rate for a new term — rather than breaking your current mortgage and paying a penalty. Blended-and-extended renewals avoid prepayment penalties but often result in paying more over time than simply waiting for maturity and shopping the market. Always compare a blended offer against the full break-and-switch calculation.
Bridge Financing
A short-term loan that "bridges" the gap between purchasing a new home before the sale of your existing home closes. Bridge financing covers the down payment for the new purchase when your existing home hasn't sold yet. Bridge loans are typically interest-only for 30–180 days and carry higher rates than standard mortgages. At renewal, some borrowers use bridge financing to time property transitions.
C
Closed Mortgage
The most common type of Canadian mortgage. A closed mortgage restricts how much extra you can pay toward the principal each year (governed by prepayment privileges) and charges a penalty if you break the mortgage before the end of your term. The benefit: a significantly lower interest rate than an open mortgage — typically 0.50–1.50% lower. Almost all renewal offers from Canadian lenders are for closed mortgages.
CMHC (Canada Mortgage and Housing Corporation)
A federal Crown corporation that provides mortgage default insurance to lenders when a borrower purchases a home with less than 20% down payment. CMHC insurance protects the lender — not the borrower — in the event of default. Borrowers pay a one-time premium of 0.60–4.00% of the mortgage amount, added to the mortgage balance. At renewal, CMHC-insured mortgages retain their insured status when switching lenders, and insured mortgages typically qualify for better rates because the lender's credit risk is covered.
Collateral Charge
A type of mortgage registration where the lender registers a charge against your property for more than the actual mortgage amount — sometimes up to 125% of the property value. The downside at renewal: a collateral charge mortgage cannot be simply switched to a new lender — you must discharge the existing charge and re-register with the new lender, incurring legal and discharge fees of $1,000–$2,500. TD Bank and National Bank register all mortgages as collateral charges by default. If your mortgage is a collateral charge, factor the switch cost into any rate comparison at renewal.
Conventional Mortgage
A mortgage where the borrower has provided at least 20% of the property's purchase price as a down payment, meaning no CMHC mortgage default insurance is required. Conventional mortgages can have amortizations up to 30 years (extended for first-time buyers purchasing new builds as of late 2024) and are not subject to the same restrictions as insured mortgages. At renewal, conventional mortgages are classified as either "insurable" or "uninsurable" — which affects available rates and lender options.
D
Debt Service Ratio (GDS / TDS)
GDS (Gross Debt Service Ratio) measures the percentage of your gross (pre-tax) income consumed by housing costs: mortgage P&I, property taxes, heating, and 50% of condo fees. The maximum GDS for most A-lenders is 39%. TDS (Total Debt Service Ratio) adds all other debt payments — car loans, credit cards, student loans, other mortgages — to the housing costs, divided by gross income. The maximum TDS for most A-lenders is 44%. A straight renewal with your existing lender typically does not trigger new income verification; switching lenders does.
Discharge
The legal process of removing a lender's registered charge from your property's title — either when the mortgage is fully paid off or when you switch lenders (for collateral charge mortgages). A standard charge mortgage can often be transferred (assigned) to a new lender at renewal without a full discharge. A collateral charge mortgage requires full discharge to switch lenders, costing $1,000–$2,500 in legal fees. Confirm your charge type before shopping for a new lender at renewal.
E
Early Renewal
Renewing your mortgage before your current term's maturity date. Many lenders allow early renewal starting 120–180 days before maturity — sometimes without a penalty during this window, or via a blended-and-extended arrangement. Early renewal can be advantageous if you want to lock into currently favorable rates before your maturity date, but always calculate whether the potential benefit outweighs any applicable penalty or blended rate tradeoff.
Equity
The portion of your property's market value that you own outright — calculated as the current market value minus the outstanding mortgage balance. Equity grows as you pay down your mortgage principal and/or as your property value appreciates. At renewal, your equity position determines access to refinancing options (you typically need at least 20% equity), and it affects your LTV (Loan-to-Value) ratio, which impacts available rates.
F
Fixed Rate
A mortgage interest rate that is locked in for the entire duration of the term and will not change regardless of what the Bank of Canada does with its policy rate. Fixed rates offer payment certainty and protection from rate increases but typically carry a premium over variable rates and incur an IRD penalty if broken early. Fixed rates are priced primarily based on Government of Canada bond yields (particularly the 5-year bond), not the Bank of Canada overnight rate. For help choosing between fixed and variable at renewal, see our fixed vs. variable comparison guide.
G
GDS Ratio
Gross Debt Service Ratio. The percentage of your gross monthly income that covers housing costs: mortgage payments, property taxes, heating, and 50% of condo fees. Maximum is typically 39% for A-lender qualifying purposes. See full definition under "Debt Service Ratio" above.
Government of Canada Bond Yield
The interest rate earned on Government of Canada bonds. 5-year GoC bond yields are the primary driver of 5-year fixed mortgage rates in Canada. When bond yields rise, fixed mortgage rates typically follow within days or weeks — and when yields fall, fixed rates soften. This is why fixed rates don't always move in step with the Bank of Canada overnight rate decisions.
H
HELOC (Home Equity Line of Credit)
A revolving credit facility secured against the equity in your home — similar to a credit card but at a much lower interest rate (typically prime + 0.50%). HELOCs allow you to borrow up to 65% of your home's appraised value (or up to 80% of value if combined with a mortgage balance). Unlike a mortgage, interest on a HELOC is calculated daily and you only pay interest on the outstanding balance. HELOCs are always variable rate (prime-linked) and are often registered as a collateral charge. Accessing a HELOC requires refinancing, not just renewal.
High-Ratio Mortgage
A mortgage where the down payment is less than 20% of the purchase price, resulting in a loan-to-value ratio above 80%. High-ratio mortgages require CMHC mortgage default insurance (or coverage from Sagen or Canada Guaranty) and must have a maximum 25-year amortization. At renewal, high-ratio mortgages retain their insured status, which can benefit the borrower — insured mortgages are eligible for lower rates at lenders because the lender's credit risk is covered by the insurer.
I
Insurable Mortgage
A mortgage that meets the eligibility criteria for default insurance even if the borrower isn't required to purchase it (because their LTV is below 80%). An insurable mortgage must have a purchase price below $1 million, a maximum 25-year amortization, and meet stress test requirements. At renewal, insurable mortgages access competitive pricing because lenders can securitize them at favorable terms. Ask your broker whether your mortgage is "insurable" or "uninsurable" — it materially affects the rates available to you.
IRD (Interest Rate Differential) Penalty
The penalty for breaking a fixed-rate closed mortgage before the end of the term. The IRD is calculated as the difference between your contracted mortgage rate and the lender's current rate for the remaining term, multiplied by your outstanding balance and the number of months remaining. Major chartered banks calculate IRD using their inflated posted rates, which can result in penalties of $15,000–$40,000+ on large mortgages. Monoline lenders use contract rates in their IRD calculations, resulting in significantly fairer penalties. At renewal, if you're considering a long fixed-rate term and might break early, choose a monoline lender — or choose a variable rate with a simpler 3-month interest penalty.
L
Lender
Any institution that provides mortgage financing. In Canada, lenders include: A-lenders (Schedule I banks — RBC, TD, BMO, Scotiabank, CIBC, National Bank; credit unions; monoline lenders); B-lenders (alternative lenders, trust companies); and private lenders (individuals or syndicates). At renewal, you are not obligated to stay with your existing lender — shopping the market, particularly through a mortgage broker, is always recommended.
LTV (Loan-to-Value Ratio)
The ratio of your outstanding mortgage balance to your property's current market value, expressed as a percentage. A $400,000 mortgage on a $600,000 property has an LTV of 66.7%. At renewal, your LTV affects the rates available to you and the products you can access. LTV below 65% generally qualifies for the best rates. LTV above 80% means your mortgage remains in insured or insurable territory. Maximum LTV for a cash-out refinance is 80%.
M
Maturity Date
The date on which your current mortgage term ends and the full outstanding balance becomes due. This is your renewal date — the most important date in your mortgage calendar. If you don't act, most lenders will auto-renew you into a short-term open mortgage at an unfavorable rate. Begin shopping at least 120 days (4 months) in advance to secure rate holds and compare your options. Use our mortgage renewal checklist for a month-by-month timeline.
Monoline Lender
A lender that offers only mortgage products — no chequing accounts, credit cards, or other banking services. In Canada, prominent monolines include First National Financial, MCAP, Merix Financial, and Radius Financial. Monolines distribute almost exclusively through mortgage brokers (not directly to consumers). They often offer lower rates than the Big 6 banks and calculate IRD penalties more fairly. At renewal, comparing monoline rates through a broker frequently uncovers significant savings.
Mortgage Broker
A licensed intermediary who represents the borrower, not the lender. A mortgage broker has access to rates and products from multiple lenders — often 30 or more — and matches borrowers to the best available product for their situation. Mortgage brokers are paid a commission by the lender, so the service is free to you at renewal. Working with a broker typically results in better rates, better product features, and unbiased advice on term selection compared to dealing exclusively with your existing lender. Learn more in our mortgage broker at renewal guide.
Mortgage Stress Test
A qualifying requirement mandated by OSFI (for federally regulated lenders) requiring borrowers to demonstrate they can afford mortgage payments at a rate higher than their actual contract rate. As of 2026, borrowers must qualify at the greater of: their contract rate plus 2%, or 5.25% (the floor rate). Crucially since 2024, straight switches between lenders at renewal are exempt from the stress test — borrowers switching lenders at renewal with the same mortgage amount and amortization do not need to re-qualify at the stress test rate.
N
NOA (Notice of Assessment)
The document issued by the Canada Revenue Agency after processing your annual income tax return. It confirms your reported income, total taxes assessed, and any amount owed or refunded. NOAs are a primary income verification document for mortgage applications and renewals involving a lender switch. Most lenders require the two most recent NOAs for self-employed borrowers. For T4 employees switching lenders, a recent NOA may be requested alongside recent pay stubs.
Negative Amortization
A situation where your mortgage payment is insufficient to cover all the interest owing in a period, causing the unpaid interest to be added to your principal balance — making your mortgage balance grow rather than shrink. Negative amortization can occur with VRM (Variable Rate Mortgage) products that hit their trigger rate in a rising rate environment. During the 2022–2023 hiking cycle, many VRM holders in Canada experienced negative amortization.
O
Open Mortgage
A mortgage that can be fully paid off, broken, or refinanced at any time without penalty. The tradeoff: open mortgages carry rates substantially higher than closed mortgages — typically 0.50–1.50% more. Open mortgages are appropriate only in specific short-term situations: when you're expecting a property sale, an inheritance, or another event that will pay off the mortgage within months. At renewal, being rolled into an open mortgage (as many lenders do automatically if you don't renew by your maturity date) is a warning sign to act quickly.
OSFI (Office of the Superintendent of Financial Institutions)
Canada's federal banking regulator, responsible for supervising federally regulated financial institutions. OSFI sets the rules for mortgage lending at Schedule I banks and federally regulated lenders — including the mortgage stress test (Guideline B-20). Credit unions and some provincial trust companies are regulated provincially, not by OSFI. OSFI's 2024 rule change allowing stress-test-free switches between federally regulated lenders was a major development for borrowers at renewal.
P
P&I Payment (Principal and Interest)
Your regular mortgage payment consists of two components: principal (the portion that reduces your outstanding mortgage balance) and interest (the cost of borrowing). Early in a mortgage, the majority of each payment goes to interest. Over time, as the balance decreases, more of each payment goes to principal. At renewal, your P&I payment will change to reflect your new interest rate and the remaining amortization — even if you choose the same term type, your payment will differ because your balance is lower and your amortization is shorter.
Portability
A feature on most closed fixed and variable rate mortgages that allows you to transfer your existing mortgage (including its rate and terms) to a new property when you sell your current home. Portability means you can avoid breaking your mortgage and paying an IRD penalty if you move during your term. Not all mortgages are portable — confirm with your lender or broker. Portability windows are typically 30–90 days; if your new property requires a larger mortgage, the additional amount will be at the new market rate (blended).
Posted Rate
The advertised "rack rate" published by major chartered banks — not the rate actually charged to borrowers. Banks post rates significantly above discounted market rates, typically 1.0–1.5% higher. Posted rates matter primarily because they are used in the IRD penalty calculation at major banks. Because posted rates are inflated, the IRD penalty is correspondingly large. Monoline lenders use contract rates (not posted rates) in their IRD calculations, resulting in substantially lower penalties.
Prepayment Privilege
The contractual right to make extra payments toward your mortgage principal beyond your regular payment schedule, without incurring a penalty. Most closed Canadian mortgages offer annual prepayment privileges of 10–20% of the original mortgage amount. Common forms include lump-sum payments (up to 15% of the original principal per year) and payment increases (up to 15–20% above the original payment per year). At renewal, choose prepayment privileges that match your financial goals — if you're planning to pay down aggressively, look for a 20% lump-sum option.
Prime Rate
The benchmark interest rate used by Canadian banks as the basis for variable rate mortgages and lines of credit. Prime rate is typically set at the Bank of Canada overnight rate + 2.20%. As of early 2026, with the BoC rate at 2.25%, prime rate is 4.45%. Variable rate mortgages are priced as prime minus a discount (e.g., prime minus 0.50% = 3.95%). When the BoC raises or cuts rates, prime rate adjusts by the same amount the next business day, and your variable rate mortgage payment (ARM) or rate (VRM) changes accordingly.
Private Lender
An individual investor or private lending syndicate that provides mortgage financing outside the regulated banking system. Private mortgages typically carry rates of 8–15%, plus lender fees of 1–3% of the mortgage amount. They exist to serve borrowers who cannot qualify with A-lenders or B-lenders — often due to very poor credit, recent bankruptcy, or unusual income situations. Private mortgages are typically short-term (6 months to 2 years) with the expectation that the borrower will rehabilitate their credit and transition to a B- or A-lender at renewal.
R
Rate Hold
A commitment from a lender to honour a specific interest rate for a defined period — typically 90 to 120 days — while you complete your renewal process. Rate holds are free and non-binding. You're not obligated to take the product, but if market rates rise before your maturity date, you're protected. A mortgage broker can simultaneously hold rates with multiple lenders on your behalf. Rate holds are most valuable when current rates are favorable and your maturity date is 2–4 months away.
Refinancing
Breaking your existing mortgage and replacing it with a new one — usually to access equity, change the amortization, consolidate debt, or restructure the mortgage. Refinancing differs from renewal: renewal replaces an expired term with a new one (same balance, same amortization trajectory), while refinancing changes the fundamental mortgage structure. See our detailed renewal vs. refinancing comparison. Refinancing triggers an IRD or 3-month interest penalty if done mid-term, plus legal fees. To access equity through refinancing, you generally need at least 20% equity remaining after the refinance (maximum 80% LTV).
Renewal
The process of signing a new mortgage contract at the end of your current term. At renewal, you choose a new term, rate type, and rate — and you may stay with your current lender or switch to a new one. Renewal does not change your outstanding principal balance or your amortization trajectory. It is the single best opportunity to shop for a better rate, and the moment where most Canadians leave significant money on the table by simply signing their existing lender's offer without comparison. See our full Mortgage Renewal Guide.
Renewal Offer
The written document your existing lender sends 21–120 days before your maturity date, offering you a new rate and term to continue your mortgage with them. Lenders are required by law to notify you at least 21 days before maturity, but most send offers earlier. The renewal offer is a starting point for negotiation — not a take-it-or-leave-it ultimatum. Renewal offers from existing lenders are frequently not their best rates. Always shop the market and use competing offers to negotiate — or switch to a new lender.
S
Standard Charge
The most common form of mortgage registration in Canada, where the lender registers a charge against your property for exactly the amount of your mortgage. A standard charge mortgage can be transferred (assigned) to a new lender at renewal without a full discharge — the new lender simply steps into the same registered position. This is what makes a "straight switch" at renewal fast and low-cost. Contrast with a collateral charge, which requires full discharge (and associated fees) to switch lenders.
Switch / Transfer
Moving your mortgage from one lender to another at renewal without changing the mortgage amount, amortization, or property — also called a "straight switch." Since 2024, straight switches between federally regulated lenders are exempt from the mortgage stress test, significantly reducing the barrier to switching. The new lender typically covers legal costs in most cases. Switching lenders at renewal often results in meaningfully better rates and is free or very low cost to execute. See: Switching Lenders at Renewal.
T
TDS (Total Debt Service Ratio)
The percentage of gross household income consumed by all debt obligations: housing costs (mortgage P&I, property tax, heat, 50% of condo fees) plus all other monthly debt payments (car loans, student loans, credit card minimums, lines of credit, other mortgages). The maximum TDS at most A-lenders is 44%. At a straight renewal with your existing lender, TDS is typically not re-evaluated. If you're switching lenders, the new lender will review both GDS and TDS ratios.
Term
The length of time your current mortgage contract is active — typically ranging from 6 months to 5 years in Canada (with some lenders offering 7- or 10-year terms). Your rate, payment, and mortgage conditions are locked in for the duration of the term. When the term ends on the maturity date, you renew or refinance. Choosing the right term at renewal is one of the most consequential financial decisions a homeowner makes. See: Mortgage Term Lengths at Renewal.
Title Insurance
An insurance policy that protects homeowners and lenders against financial loss from title defects, fraud, encroachments, and other title-related problems. At renewal with a new lender, title insurance is typically required and usually costs $150–$350 as a one-time premium — much less than traditional title searches. Many lenders cover title insurance costs for borrowers switching through a straight-switch process, making the switch essentially free for the borrower.
Trigger Rate
Applicable only to VRM (Variable Rate Mortgage) products where the monthly payment amount stays fixed even as the interest rate changes. The trigger rate is the point at which your fixed monthly payment no longer covers the full interest owing — meaning your principal balance begins to grow (negative amortization). During the 2022–2023 rate hiking cycle, tens of thousands of Canadian VRM holders hit their trigger rates and were required to increase payments or make lump-sum contributions. When evaluating variable rate products at renewal, always confirm whether you're looking at an ARM (payment adjusts with rate) or VRM (payment stays fixed, trigger rate risk applies).
U
Uninsurable Mortgage
A mortgage that does not meet CMHC's eligibility criteria for default insurance and cannot be insured even with 20%+ equity. Uninsurable mortgages include: properties over $1 million purchase price, mortgages with amortizations greater than 25 years, and cash-out refinances where equity is being taken out. Uninsurable mortgages access a narrower pool of lenders and typically carry slightly higher rates than insurable mortgages because the lender retains the full credit risk.
V
Variable Rate
An interest rate that fluctuates with the lender's prime rate, which tracks the Bank of Canada overnight rate. Variable rate mortgages come in two forms: ARM (payment adjusts with rate changes) and VRM (payment stays fixed but the principal/interest split changes). Variable rates are expressed as prime plus or minus a discount: e.g., "prime minus 0.50%." As of early 2026, with prime at 4.45%, a variable at prime minus 0.50% = 3.95%. Variable rate mortgages carry a 3-month interest penalty to break, compared to the potentially much larger IRD for fixed rate mortgages. Historically, variable rates have outperformed fixed rates in Canada over long periods.
VRM (Variable Rate Mortgage)
A specific type of variable rate mortgage where the monthly payment amount stays constant even as the interest rate changes. When rates rise, more of each payment goes to interest and less to principal; when rates fall, more goes to principal. This is in contrast to an ARM, where the payment itself adjusts. VRMs are subject to trigger rate risk. Offered by TD, CIBC, and some credit unions. Borrowers with VRMs during the 2022–2023 rate hikes often saw their trigger rates exceeded, requiring payment increases or lump-sum contributions to restore amortization schedules.
