Mortgage basics

Master the fundamentals. Sign with confidence.

Five concepts explain ninety percent of every mortgage you'll ever be offered. Here they are, in the plain language we'd use sitting across from you.

Down payments

How much you really need down.

A conventional mortgage means at least 20% down. You avoid mortgage default insurance entirely, and more amortization options open up.

An insured (high-ratio) mortgage lets you buy with as little as 5% down on the first $500,000 of the price and 10% on the portion above that. The trade: a one-time default-insurance premium, paid at closing or rolled into the mortgage. We'll show you the exact number before you decide.

Where does the money come from? Savings, a gift from immediate family (very common, perfectly acceptable to lenders), your FHSA, or the RRSP Home Buyers' Plan — up to $60,000 per person, tax-free, repaid over 15 years. A well-timed RRSP contribution before you withdraw can even generate a tax refund you put toward closing costs.

Open, closed & convertible

The lock on the door, and what it buys you.

A closed mortgage commits you for the term in exchange for a lower rate. Pay it off early or renegotiate beyond your allowed limits and a prepayment penalty applies. For most people staying put, closed is the cheaper, sensible default.

An open mortgage can be repaid in part or in full at any time without penalty — freedom you pay for with a noticeably higher rate. It earns its keep when a sale, inheritance or big bonus is genuinely on the horizon.

A convertible closed mortgage splits the difference: closed-mortgage pricing with the right to convert into a longer closed term at any time, without prepayment charges.

Fixed & variable rates

Certainty, or the odds. Both are legitimate.

A fixed rate locks your interest rate for the whole term: the same payment, month after month, no matter what the Bank of Canada does. You pay a little extra for that certainty.

A variable rate moves with your lender's prime rate. With many variable products the payment itself stays level — when rates fall, more of each payment attacks the principal; when rates rise, more goes to interest. Historically variable has often won on total cost.

Both come in open and closed varieties, and switching between them mid-stream is often possible — locking a variable into a fixed, for instance. There's no universal right answer: it comes down to your budget, your timeline, and how you sleep at night. We'll run it with your numbers, not a rule of thumb.

Amortization

The dial that sets your payment, and your interest bill.

Your amortization is the number of years it takes to pay the mortgage off entirely — classically 25 in Canada. It's the biggest lever on your monthly payment, and it pulls in both directions.

Shorter amortization: higher payments, dramatically less interest over the life of the loan, equity built faster, mortgage-free sooner.

Longer amortization: lower, easier payments — genuinely useful for first budgets — at the cost of more total interest and slower equity. Insured mortgages top out at 25 years (30 for eligible first-time buyers and new builds); with 20% or more down, longer amortizations become available.

Amortization isn't permanent: prepayment privileges (below) let you shorten it year after year, without renegotiating anything.

Prepayment privileges

The fine print that pays you back.

A prepayment privilege is your right to pay extra against the principal, before it's due, without penalty. Every extra dollar skips the interest queue entirely, which is why lenders limit it: your prepayment is their lost interest.

Most closed mortgages allow a set percentage each year — commonly 10–20% of the original principal — plus the right to increase your regular payment. On a $400,000 mortgage with a 15% privilege, that's up to $60,000 a year you could pay down penalty-free.

Exceed the privilege and the penalty is typically three months' interest or the interest rate differential. If paying down fast matters to you — bonuses, tax refunds, a rising income — tell us up front and we'll prioritize lenders with generous prepayment room. If it doesn't, that flexibility is a bargaining chip we can sometimes trade for a sharper rate.
