BUYING

The bond market just shrank what Ottawa buyers can borrow

The bond market just shrank what Ottawa buyers can borrow

On Friday the five-year Government of Canada bond yield was trading around 3.36%. That is up eight basis points on the week and sits three basis points below its highest level in twelve months. Lenders did what lenders do. Fixed rates on three, four and five year terms went up 10 to 15 basis points, and a few by 20.

Almost nobody in Ottawa noticed, because the conversation this week is September 2 and whether the Bank of Canada holds at 2.25% again. But the rate most of my buyers will actually sign moved the other way while everyone watched the wrong meeting, and it costs more than the payment math suggests.

The payment change is small. Let's say that out loud and move on.

Ottawa's townhouse benchmark is $542,500. Twenty percent down leaves a $434,000 mortgage. Over 25 years at 3.94%, which was the best insured five-year fixed showing on Ratehub last Friday, that is about $2,269 a month. At 4.09%, after a 15 basis point bump, it is $2,304.

Thirty-five dollars a month. Two thousand one hundred over a full five-year term. If that number is deciding your purchase, the bond market is not your problem.

I wrote back in July about why fixed and variable rates are priced off completely different things, and I am not going to run that explainer again. The mechanism is not the interesting part this week. The consequence is.

The approval change is the part nobody quotes you

Your stress test qualifying rate is your contract rate plus two percent, or 5.25%, whichever is higher. Every buyer knows that. What most have not thought through is that the qualifying rate rides on the contract rate, so when the bond market moves your fixed quote 15 basis points, it moves your approval ceiling 15 basis points too.

Run it on the same townhouse. A buyer who qualified at 3.94% was tested at 5.94% and cleared $434,000. Same income, same down payment, same car loan, tested three weeks later at 6.09%, and the mortgage becomes $427,998. That is $6,002 less borrowing, which at 20% down is roughly $7,500 less house.

If your lender passed through the full 20 basis points, you are testing at 6.16% and you have lost $8,758 of mortgage and about $11,000 of purchase price.

On the $634,000 composite benchmark, the same move costs about $7,000 of mortgage.

None of that is a catastrophe. It is also the number your lender quietly re-runs the day your rate hold expires. Thirty-five dollars a month is the headline. Seven thousand five hundred dollars of buying power is the actual event.

A Bank of Canada cut does not fix this

I have had three versions of this conversation in the last two weeks.

The policy rate sets prime. Prime sets variable. If you are taking a variable mortgage, then yes, September 2 matters to you, and a cut is worth about $60 a month on that same $434,000 mortgage.

If you are taking a fixed mortgage, and most first-time buyers in Ottawa still do, the Bank of Canada does not set your rate. The five-year bond does. Your qualifying rate is anchored to a number the Bank of Canada does not control, and that number just hit a twelve-month high because of American debt levels, an expired ceasefire and the price of oil. Waiting for a policy cut to improve your approval is pulling a lever that is not connected to anything.

It gets worse for the waiters. TD Securities said yesterday it expects the overnight rate to sit at 2.25% through the rest of 2026 and then rise to 2.75% in 2027 through two quarter-point increases. National Bank also has the rate flat through year end. Markets put the odds of a cut by the October 28 decision at roughly a third. The cut people are waiting for is not the base case at any major desk I can find.

When I wrote in early August that waiting for a rate cut was costing Ottawa buyers money, the five-year yield was 3.22%. It is 3.36% now. The waiting has already been priced.

If you are holding a pre-approval from June, go look at the expiry date

A rate hold runs 90 or 120 days, and a sub-4% hold written in June is worth real money right now. It went into the money while you were on vacation. Most buyers treat the hold as paperwork. It is the cheapest financing available to you and it has a hard stop date. I covered the mechanics in pre-approval versus pre-qualification. The rules have not changed. The value of the hold has.

Ron Butler of Butler Mortgage put it bluntly in Canadian Mortgage Trends last week: if you see a fixed rate below 4.19%, or below 4.10%, take it, and stop waiting for rates that start with a two. I do not make rate calls. I am noting that the people who do are not describing a market that gets cheaper if you wait.

Ottawa's supply is still doing more for you than any rate will

Here is the balance. There were 4,678 active listings at the end of July, the highest July count in a decade and about 44.5% above the ten-year average, with 3.5 months of inventory. I went through what that supply number means against Ottawa's own normal a couple of days ago, and you can see the current inventory here.

The townhouse benchmark is also down 5.1% year over year. In dollars that is roughly $29,154 off the same house twelve months ago, worth about $124 a month on the mortgage. Three and a half times what the rate move cost you.

So price still beats rate in Ottawa, comfortably. What changed in August is that the price discount stopped being free. All year a buyer could wait, watch prices soften, and finance at a flat or falling rate. Both clocks ran in their favour. One has now turned around, and the segments that are softest on price are the same ones where buyers borrow closest to their ceiling.

What I would actually do this week

Get the hold now, even if you are 60 days from writing an offer. It costs nothing and it fixes your qualifying rate at today's number instead of October's.

Ask your lender what you qualify for at today's rate, not the one on your June letter. Better to find out now than during a conditional period.

And if you are weighing fixed against variable, that is a risk tolerance question, not a math question. RMG's Bruno Valko makes the point that today's variable discounts leave enough buffer to absorb roughly three quarter-point increases before you are worse off. Butler thinks the risk of increases in 2027 is real. Both can be true. Which one matters depends on whether a $184 monthly increase would break you.
