The Advertised Variable Rate Is a Floor, and Most Borrowers Start Above It

The lowest variable rate on a comparison site was priced for one specific borrower, and the lender assumed it wouldn't be you. That borrower is buying a home to live in, putting less than 20% down so the mortgage carries default insurance, and has clean credit and comfortable debt ratios. Everyone else gets priced from that starting line, upward.

If you've ever sat across from a quote that came in higher than the number you screenshotted, you've run into this. It feels like a bait and switch, and it pushes people to chase the wrong offers or sign a renewal out of frustration. The advertised rate is real, but it only works as a floor. What you're actually comparing between lenders is your own spread, and once you can read one, every quote on your table makes sense.

How a variable rate is actually built

A Canadian variable rate is written as prime plus or minus a spread, such as prime minus 0.50%. Prime follows the Bank of Canada's overnight rate, so it moves for everyone at once. The spread is the part a lender sets for you, and it's locked for your whole term. When the Bank of Canada cuts, your rate drops because prime fell. Your spread stays exactly where you signed it.

So the number worth negotiating is the spread. Take an illustrative $500,000 mortgage. A spread 0.40 points worse than the headline costs roughly $2,000 a year in extra interest early in the term ($500,000 × 0.40%), every year you hold it. One more detail matters here: a few lenders use their own prime instead of the big-bank prime, so a generous-looking spread can sit on a higher base.

Four things that move your spread above the headline

Lenders run every file through an internal pricing grid. The traits that shift you along it are predictable:

  • Down payment and insurance. Oddly, putting less than 20% down often gets you a thinner spread, because CMHC, Sagen or Canada Guaranty insurance takes the default risk off the lender. That protection isn't free. At 10% down, the CMHC premium is 3.10% of the mortgage, so the honest comparison sets the premium against the rate gap over your term.
  • Purchase or refinance. Refinances can't be insured under federal rules, so pulling equity out to consolidate debt usually prices higher than a first-time purchase in Duncan.
  • Property type and use. A standard owner-occupied home in town tends to get the sharpest pricing. Rentals, second homes and some larger rural acreages around the Cowichan Valley often don't.
  • Credit and ratios. Lenders draw lines on credit score and debt service ratios, and the best discounts sit above them. Lifting your score before you apply can narrow the spread you're offered.

None of these will stop you qualifying. The stress test still applies on top, at the higher of your contract rate plus 2 percentage points or 5.25%.

How to read a variable quote in three checks

Before you compare anything, ask each lender for three answers:

  1. What's the spread, and off which prime? Line the offers up as spreads on the same base, and ignore the total rate until you do.
  2. Which pricing tier am I in? Insured or conventional, purchase or refinance, owner-occupied or rental. If your file differs from the headline borrower, expect the gap and ask how big it is.
  3. What comes with the rate? The deepest discounts sometimes come with restricted features like no portability or heavy discharge fees. A standard variable penalty is three months' interest; confirm yours is. If your mortgage is insured, it can usually move to another lender at renewal without being stress-tested again, which keeps your negotiating position strong next time.

A slightly wider spread with flexibility a growing family will actually use can beat the lowest number on the screen. Once you know your tier, the advertised rate is just a reference point, and you'll be able to tell a good offer from a merely low one.
