Canadian Mortgage Glossary 2026: 60+ Terms Every Buyer Should Know

Mortgage paperwork in Canada is dense with three-letter acronyms and terms that mean something specific (and sometimes expensive) once you sign. This glossary covers every term you will actually see on your 2026 application, commitment letter, and renewal offer — in plain English, with real-dollar examples where it matters.

A — Foundations

Amortization. The total length of time it takes to pay off your mortgage, assuming the rate and payment stay the same. In Canada, the maximum is 30 years for insured first-time buyers on a new build, 25 years for most other insured mortgages, and 30-35 years for uninsured mortgages with 20%+ down.

Appraisal. A professional opinion of your home's market value, ordered by the lender to confirm the property is worth what you are paying. Typical cost: $300-$500.

APR (Annual Percentage Rate). The contract rate plus lender fees, expressed as a single annualized number. APR is more honest than the headline rate because it includes fees.

Approval in Principle. A soft pre-approval that tells you what you might qualify for, but is not a binding offer. A commitment letter is the binding document.

B — The Bank and Bond Side

Bank of Canada (BoC). Sets the overnight rate, which drives prime rate, which drives variable mortgage rates.

Blend and Extend. Mid-term refinance where the lender blends your existing rate with today's rate, often without a prepayment penalty. Useful when rates have dropped and you want to lock in.

Bond Yield (5-Year Canada). The benchmark that fixed mortgage rates are priced off. Lenders typically add 1.25%-1.75% on top of this yield to set their advertised 5-year fixed rate.

Bridge Financing. A short-term loan that lets you close on your new home before your old one sells. Usually 90-180 days, priced at prime + 2%-4%.

C — Closing and Costs

Cash Back Mortgage. A mortgage that gives you a lump sum at closing (typically 1%-7% of the mortgage amount) in exchange for a higher rate. Useful for closing costs but expensive over the term — see our [cash back mortgage guide][[link:cashback-mortgage-canada-2026]] for the full math.

Closing Costs. Land transfer tax, legal fees, title insurance, adjustments — typically 1.5%-4% of purchase price. In Toronto and Vancouver, expect higher because of double land transfer tax (Toronto) and the BC PTT.

CMHC. Canada Mortgage and Housing Corporation — the government insurer that backstops most insured (high-ratio) mortgages.

Conventional Mortgage. A mortgage where you put down 20% or more, so default insurance is not required.

D — Down Payment and Debt

Down Payment. Minimum is 5% on the first $500K, 10% on the portion from $500K to $1.5M, and 20% on anything above $1.5M (the 2026 insurable cap).

Debt-to-Income Ratios:

• GDS (Gross Debt Service) — Housing costs (P&I + property tax + heat + 50% condo fees) ÷ gross income. Most lenders cap at 39%.
• TDS (Total Debt Service) — GDS + all other debts (car loans, credit cards minimums, student loans, lines of credit). Cap is usually 44%.

Default Insurance. Required when down payment is under 20%. Premium is 2.8%-4.0% of the loan, added to your mortgage balance.

E — Equity and Extras

Equity. Your home's value minus what you owe. The portion you "own" outright.

ETF Mortgage (NOT bank ETF). Slang for a "no-frills" mortgage with restrictions on prepayment, porting, and lender switching at renewal — in exchange for a lower rate. Read the fine print before accepting.

F — Fixed and Frequency

Fixed Rate. Your interest rate stays the same for the entire term (usually 1, 2, 3, 4, 5, 7, or 10 years). Payment never changes.

FHSA (First Home Savings Account). A 2023+ registered account that combines RRSP-style tax deductions with TFSA-style tax-free withdrawals for a first home. Limit is $8K/year, $40K lifetime, and (per 2026 rules) stackable with the RRSP Home Buyers' Plan.

G-I — Through the Middle

HELOC (Home Equity Line of Credit). Revolving credit secured against your home equity, typically priced at prime + 0.50% in 2026.

High-Ratio Mortgage. A mortgage with less than 20% down — requires default insurance.

IRD (Interest Rate Differential). The penalty for breaking a fixed-rate mortgage early. Big-bank IRD calculations are notorious — penalties of $15,000-$30,000 on a $500K mortgage are common. Monoline lender IRDs are usually one-third the size.

P — Prepayment and Prime

Payment Frequency. Monthly, semi-monthly, bi-weekly, weekly. Accelerated bi-weekly sneaks in one extra monthly payment per year and shaves ~3 years off a 25-year amortization.

Porting. Taking your existing mortgage (rate and balance) to a new property when you move, avoiding a break penalty.

Prepayment Privileges. How much extra you can pay each year without penalty. Standard in 2026 is 15/15 (15% lump sum + 15% payment increase per year).

Prime Rate. The base lending rate at the major banks. Moves in lockstep with the BoC's overnight rate.

R-S — Renewal and Stress Test

Renewal. When your term ends and you sign on for another. As of late 2024, straight switches at renewal no longer require the stress test — meaning you can shop competitively without re-qualifying.

Stress Test. Federal qualifying rate. In 2026, you must qualify at the greater of 5.25% or your contract rate + 2.00%. Applies to all federally regulated lenders for purchases, refinances, and lender switches that increase the balance.

V — Variable

Variable Rate Mortgage (VRM). Rate floats with prime. Two flavours:

• Adjustable Payment VRM — payment changes when rates move.
• Static Payment VRM — payment stays fixed; the principal/interest split changes. Risk: hitting the trigger rate, where the payment no longer covers interest.
