Last week, the Bank of Canada made its second rate announcement of 2026 — and for the second consecutive time, held the overnight rate steady at 2.25%. On the surface, a hold might sound like business as usual. But underneath that decision sits a collision of forces that every Ontario homeowner, buyer, and anyone approaching a renewal or refinance needs to understand: rising oil prices driven by the US–Iran conflict, climbing bond yields, inflation uncertainty, and a softening labour market all pulling in different directions.
Here's what's actually happening, what it means for fixed and variable mortgage rates, and what you should be doing about it right now depending on your situation.
What the Bank of Canada Said on March 18
The BoC held its target for the overnight rate at 2.25%, with the Bank Rate at 2.50% and the deposit rate at 2.20%. This is the second consecutive hold after a series of rate cuts through the second half of 2025 that brought the rate down from its peak.
The accompanying statement highlighted three key themes that directly affect where rates are headed:
- Inflation is easing — but not evenly. CPI inflation fell to 1.8% in February, down from 2.3% in January. That's below the Bank's 2% target, which under normal circumstances would support further rate cuts. But these aren't normal circumstances.
- The labour market is weakening. Employment gains from late 2025 have largely reversed in the first two months of 2026, and the unemployment rate rose to 6.7% in February. This is the kind of weakness that would typically push the Bank toward further easing.
- Geopolitical uncertainty is the wildcard. The Bank explicitly noted the US–Iran conflict as adding a new layer of uncertainty to the economic outlook. Translation: they want to cut, but they're worried about what's coming next on the inflation front.
Why the BoC Didn't Cut Despite Weak Economic Data
The Bank is caught between a slowing economy (which argues for lower rates) and rising energy costs from the Iran conflict (which threaten to reignite inflation). When those two forces collide, central banks tend to do nothing — and that's exactly what happened. The next announcement is April 29, 2026, and the direction will depend heavily on what happens with oil prices in the next five weeks.
The US–Iran Conflict and the Oil Price Surge
The elephant in the room is crude oil. Since the escalation of the US–Iran conflict, oil prices have risen sharply. As of today (March 24, 2026), WTI crude is trading at approximately $92.35 per barrel, up more than 4% in a single session. Brent crude has climbed back above $104 per barrel.
Why does this matter for mortgage rates? The connection runs through two channels:
Channel 1: Oil → Inflation → BoC Policy
Higher oil prices flow directly into consumer costs — gasoline, heating, food transportation, manufacturing inputs. If oil stays above $90–100 for an extended period, it will push CPI inflation back above the Bank's 2% target. That takes further rate cuts off the table and, in a worst case scenario, puts rate increases back into the conversation. The current market consensus is that the BoC will hold at 2.25% for the remainder of 2026, but if oil pushes toward $120–140 per barrel, that consensus could shift quickly.
Channel 2: Oil → Bond Yields → Fixed Rates
Five-year fixed mortgage rates in Canada don't follow the BoC overnight rate — they track the Government of Canada 5-year bond yield. Today, that yield sits at 3.23%, and it has been trending upward since the Iran conflict escalated. When bond investors fear future inflation, they demand higher yields to compensate. Higher bond yields mean higher fixed mortgage rates. Lenders have already increased fixed rates by an estimated 10 to 15 basis points since the conflict began.
| Indicator | Current Level (Mar 24) | Direction | Mortgage Impact |
|---|---|---|---|
| BoC Overnight Rate | 2.25% | — Hold | Variable rates stable for now |
| 5-Year Bond Yield | 3.23% | ▲ Rising | Fixed rates under upward pressure |
| WTI Crude Oil | $92.35/bbl | ▲ Rising | Inflation risk = rates stay high or rise |
| Brent Crude Oil | $104.49/bbl | ▲ Rising | Global energy cost feeding into CPI |
| CPI Inflation (Feb) | 1.8% | ▼ Falling | Supports cuts — but oil threatens reversal |
| Unemployment Rate (Feb) | 6.7% | ▲ Rising | Supports cuts — economy weakening |
Rate Scenarios: Where Could Things Go From Here?
Nobody can predict rates with certainty, but we can map out the most likely scenarios based on what's happening right now:
| Scenario | What Triggers It | Likely Impact on Rates |
|---|---|---|
| Scenario A: Conflict De-Escalates | Ceasefire, diplomatic resolution, oil drops below $80 | BoC resumes cutting (possibly −0.25% in April or June). Fixed rates ease 15–25 bps. Best case for borrowers. |
| Scenario B: Stalemate (Most Likely) | Conflict continues, oil stays $85–100, inflation hovers near 2% | BoC holds at 2.25% for remainder of 2026. Fixed rates drift sideways or slightly higher. Variable rates unchanged. |
| Scenario C: Escalation | Full Strait of Hormuz disruption, oil spikes to $120–140+ | BoC forced to consider rate increases. Fixed rates jump 30–50+ bps. Pain for floating and renewing borrowers. |
My Assessment — March 24, 2026
Scenario B is the most probable path over the next 3–6 months. The conflict is unlikely to resolve quickly, but a full Strait of Hormuz shutdown remains a tail risk rather than a base case. Plan for rates to stay roughly where they are, but protect yourself against Scenario C by locking in sooner rather than later if you have a renewal or purchase on the horizon.
What This Means If You're a New Buyer in Ontario
If you're looking to purchase a home in Ontario this spring, the current rate environment creates both challenges and opportunities.
The challenge: Fixed rates are slightly higher than they were in January, and there's no guarantee they'll come back down in the near term. The BoC's hold means variable rates aren't going lower either.
The opportunity: The softening labour market and geopolitical uncertainty are keeping some buyers on the sidelines, which means less competition in many Ontario markets. Spring 2026 is shaping up to be a more balanced market than the frenzy of prior years — and that gives you more negotiating power.
My Recommendation for Buyers
- Get pre-approved now to lock in today's rate. Most pre-approvals hold your rate for 90–120 days. If rates rise further due to oil prices, you're protected. If rates drop, we can renegotiate before closing.
- Don't wait for “the perfect rate.” Trying to time the bottom of interest rates is like trying to time the stock market — you'll almost always miss it. A rate that works within your budget today is better than a theoretical rate that may or may not arrive in six months.
- Consider a variable rate with a fixed-payment structure if you believe the conflict will eventually resolve and rates will ease. This gives you the benefit of any future BoC cuts while keeping your monthly payment predictable.
Buying a Home This Spring?
Lock in today's rate before bond yields push fixed rates higher. We'll compare 40+ lenders, hold your best rate for up to 120 days, and guide you through the process — at zero cost to you.
Get Pre-Approved Now →What This Means If Your Renewal Is Coming Up
If your mortgage term ends in the next 6–12 months, you are in the most time-sensitive position of any borrower right now. Here's why:
Many borrowers who locked in 5-year fixed rates in 2021 secured rates between 1.5% and 2.5%. Today's best 5-year fixed rates are in the 4.49–4.99% range. That means your monthly payment is going up at renewal regardless — the question is by how much, and whether it goes up even further if you wait.
My Recommendation for Renewals
- Start the renewal process 120–180 days early. Most lenders allow early renewal without penalty within this window. This lets you lock in current rates before any further increases from the Iran-related oil shock.
- Do not simply sign your bank's renewal letter. Your existing lender's renewal offer is almost never their best rate. A broker can often secure a rate 0.30–0.60% lower by shopping across 40+ lenders — and switching lenders at renewal typically costs nothing.
- Consider blending your remaining term with a new rate if you're more than 180 days from maturity. Some lenders offer blend-and-extend options that let you lock in a better rate now without breaking your current mortgage.
Renewal Coming Up in the Next 180 Days?
Lock in today's rate before bond yields push fixed rates even higher. We'll compare 40+ lenders and hold your best rate — at zero cost to you.
Start My Renewal Early →What This Means If You're Considering a Refinance
Refinancing decisions in this environment come down to one question: is there a financial benefit that outweighs the cost of breaking your current mortgage?
The most common reasons to refinance right now:
- Debt consolidation: If you're carrying high-interest debt (credit cards, lines of credit), rolling it into your mortgage at 4.5–5% can dramatically reduce your monthly payments and total interest cost — even in today's rate environment.
- Accessing equity for investment: With Ontario property values holding steady or appreciating modestly, tapping equity for a down payment on an investment property or business investment may make sense.
- Switching from variable to fixed: If you're currently on a variable rate and are concerned about Scenario C (oil spike, BoC rate hike), locking into a fixed rate now provides certainty.
My Recommendation for Refinancers
- Run the breakeven analysis first. Prepayment penalties on fixed-rate mortgages can be significant (3 months' interest or IRD, whichever is higher). We calculate the exact penalty and compare it to the savings from refinancing before you commit to anything.
- Act before rates move higher. If the Iran conflict pushes oil toward $120+ and bond yields climb further, today's refinance rate may look very attractive in hindsight.
- Don't refinance just because you can. If your current rate is competitive and you don't have a specific financial objective (debt consolidation, equity access, term change), it may be better to hold your position and review at renewal.
Considering a Refinance?
We'll calculate your penalty, compare it to the potential savings, and give you a clear recommendation — no pressure, no obligation. If refinancing doesn't make financial sense, we'll tell you that directly.

The Bottom Line
The Bank of Canada's hold at 2.25% tells you everything you need to know about the current moment: the economy is weakening, but geopolitical risks from the Iran conflict are keeping the Bank cautious. Variable rates are stable for now, but fixed rates are under upward pressure as bond yields climb alongside oil prices.
For buyers, this is still a reasonable time to purchase — spring market competition is muted, and locking in a pre-approval protects you against further rate increases. For renewals, starting early is essential — the spread between your expiring rate and today's rates means your payment is going up, and waiting only risks it going up more. For refinancers, run the numbers carefully and act with a specific financial objective in mind.
Geopolitical events are outside your control. Your mortgage strategy doesn't have to be. Whether you're buying, renewing, or refinancing — the single best thing you can do right now is get informed, get a rate hold, and make your decision from a position of knowledge rather than uncertainty.
