Why Your Fixed Mortgage Rate Can Still Go Up Even When the Bank of Canada Doesn’t Move
The fixed mortgage rate vs. Bank of Canada rate question comes up every time the Bank holds and borrowers still see higher quotes. The two rates follow different signals. The Bank of Canada has held its policy rate at 2.25% since October 2025, yet the five-year Government of Canada bond yield, which fixed mortgage pricing tracks most closely, rose from 2.73% on the day of the last cut to 3.42% on the day of the September 2, 2026 hold, according to Bank of Canada bond yield data. That gap explains why a fixed-rate quote can climb while headlines say rates are unchanged.
- Policy rate influence: The Bank of Canada policy rate has a more direct impact on prime rates and variable mortgage rates than it does on fixed mortgage rates.
- What drives fixed rates: Fixed mortgage rates are influenced more by Government of Canada bond yields and lender funding costs than by changes to the Bank of Canada's policy rate.
- Bond yields climbed: The five-year Government of Canada bond yield increased from 2.73% on October 29, 2025 to 3.42% on September 2, 2026, even as the policy rate remained unchanged at 2.25%.
- Bank commentary: In September 2026, the Bank of Canada noted that long-term bond yields had moved higher globally, including in Canada.
- Impact on homeowners: A fixed mortgage rate cannot change during your existing term. Any impact from changing bond yields is reflected when you purchase, refinance or renew a mortgage.
- Individual factors matter: Your credit profile, down payment, amortization and mortgage term can all affect the rate a lender ultimately offers you.
Fixed Mortgage Rate vs. Bank of Canada Rate: What Each One Tracks
The Bank of Canada sets a target for the overnight rate, the rate at which major financial institutions lend one-day funds to each other. Banks set their prime rates off that target, and most variable-rate mortgages are priced as prime plus or minus a set amount. When the Bank moves, prime and variable rates usually follow within days.
Fixed rates work differently. A lender offering a five-year fixed rate is committing to that rate for five years, so it prices the loan against what money costs over five years, not overnight. REMAX Canada’s September 2026 rate announcement recap summarizes: changes in the overnight rate have a more direct impact on variable mortgage rates, while fixed rates are influenced more heavily by bond yields and broader financial market conditions.
| Date | Decision | What the Bank Highlighted | Five-Year GoC Yield That Day |
|---|---|---|---|
| October 29, 2025 | Cut to 2.25% | Weak economy from U.S. trade actions; rate viewed as about the right level. | 2.73% |
| December 10, 2025 | Hold | Surprisingly strong Q3 growth of 2.6%; unemployment declined to 6.5%. | 3.01% |
| January 28, 2026 | Hold | Outlook little changed; CUSMA review identified as a key uncertainty. | 2.94% |
| March 18, 2026 | Hold | Middle East conflict lifted energy prices; Q4 GDP fell 0.6%. | 3.01% |
| April 29, 2026 | Hold | Iran war pushed inflation forecasts higher; housing activity remained constrained by affordability. | 3.26% |
| June 10, 2026 | Hold | Q1 GDP down 0.1%; CPI reached 2.8% in April. | 3.13% |
| July 15, 2026 | Hold | Growth resumed; CPI reached 3.2% in May, driven largely by gasoline prices. | 3.14% |
| September 2, 2026 | Hold | Q2 GDP rose 3.3%; new U.S. tariffs were introduced; upside inflation risks increased. | 3.42% |

How Bond Yields Set the Price of a Fixed Mortgage
Government of Canada bond yields are influenced by investor expectations for inflation and interest rates, along with broader market conditions. When investors expect higher inflation, or expect central banks to raise rates later, they demand higher yields today. Lenders pass that higher cost of money into the fixed rates they offer, plus a margin for their own funding costs, risk and profit.
That is why fixed rates can move between Bank of Canada announcements, and even in the opposite direction to the policy rate. Bond markets react to oil prices, trade news, inflation data and moves by other central banks every day.
What Happened to Bond Yields While the Bank Held
The table below lines up each decision since the Bank’s last cut with the five-year Government of Canada benchmark yield on the same day.
| Announcement Date | Policy Rate Decision | Five-Year GoC Bond Yield That Day |
|---|---|---|
| October 29, 2025 | Cut to 2.25% | 2.73% |
| December 10, 2025 | Hold at 2.25% | 3.01% |
| January 28, 2026 | Hold at 2.25% | 2.94% |
| March 18, 2026 | Hold at 2.25% | 3.01% |
| April 29, 2026 | Hold at 2.25% | 3.26% |
| June 10, 2026 | Hold at 2.25% | 3.13% |
| July 15, 2026 | Hold at 2.25% | 3.14% |
| September 2, 2026 | Hold at 2.25% | 3.42% |

Two stretches stand out. In March, the conflict in the Middle East pushed energy prices up, and the Bank’s March 18 statement noted that global bond yields had risen. CREA’s July 2026 forecast described a jump in fixed mortgage rates in late March that later partially eased.
The second move came over the summer. In its September 2 announcement, the Bank said long-term bond yields had moved up globally, including in Canada. Its summary of deliberations linked that rise to concerns about sovereign debt levels and to expectations that central bank rates would need to increase to restrain inflation.
Why Did My Mortgage Rate Change? Common Scenarios
If your rate changed and the Bank of Canada did not move, one of these is usually the reason:
- Your term renewed: A fixed rate stays the same for the entire term, but the new rate at renewal reflects the market at that time, not the rate you had before.
- Your pre-approval rate hold expired: A quote you received months ago may no longer be available once the hold period ends.
- You changed products or terms: A three-year and a five-year fixed rate are priced off different parts of the bond market.
- Your file changed: Factors that can affect the new term rate you are offered can include term length, rate type, your credit history, self-employment and discount eligibility.
- Your lender repriced: Lenders adjust their rates to compete and to reflect their own funding costs.
Variable-rate holders who saw a change during the pause should check their statement. Prime at chartered banks has not moved since the October 2025 cut, so a change in a variable payment usually traces back to a renewal, a product switch or a payment recalculation set out in the contract.
What to Do Before You Lock In a Fixed Rate
Because fixed rates can move between announcements, timing and paperwork matter:
- Get pre-approved with a written rate hold, and note its expiration date.
- Compare offers from more than one lender or a mortgage broker; these pros and cons of banks versus mortgage brokers can help you choose where to start.
- Ask how the prepayment penalty is calculated. The prepayment penalty is usually the higher of three months’ interest or the interest rate differential.
- Stress-test your budget at a higher rate, not just the rate you are quoted.
- If you already have a variable rate and want certainty, ask your lender about converting it. REMAX Canada explains the trade-offs of locking in a variable rate mortgage.

Why Did My Mortgage Rate Change If the Bank of Canada Didn't Move?
Most often, it is because your mortgage renewed, your rate hold expired, or your lender repriced its fixed-rate offerings. Fixed mortgage rates follow Government of Canada bond yields much more closely than the Bank of Canada's policy rate. Between October 2025 and September 2026, the five-year Government of Canada bond yield rose from 2.73% to 3.42% while the Bank's policy rate remained unchanged at 2.25%.
Does the Bank of Canada Set Fixed Mortgage Rates?
No. The Bank of Canada sets the target for the overnight rate, which influences prime rates and variable mortgage rates. Fixed mortgage rates are set by lenders and are influenced primarily by Government of Canada bond yields, funding costs and market conditions.
Can My Fixed Mortgage Rate Go Up During My Term?
No. A fixed mortgage rate remains unchanged for the entire term of your mortgage. Your rate can change when you renew, refinance or take out a new mortgage, because the new rate reflects market conditions and lender pricing at that time.
What Moves Five-Year Fixed Mortgage Rates in Canada?
Five-year fixed mortgage rates are influenced mainly by five-year Government of Canada bond yields, along with lender margins and funding costs. Bond yields can move in response to inflation data, oil prices, economic reports, trade developments and expectations about future central bank decisions. In September 2026, the Bank of Canada noted that long-term bond yields had risen globally, including in Canada.
Where Can I Check Current Bond Yields?
The Bank of Canada publishes daily benchmark Government of Canada bond yields, including five-year benchmark yields, through its market data resources. These figures are widely used as a reference point for fixed mortgage pricing in Canada.
