On October 28, 2026, the Bank of Canada raised its target overnight interest rate by 25 basis points from 2.25 percent to 2.50 percent, marking its first rate hike since July 2023.
At 9:45 AM ET on Wednesday, October 28, 2026, the Bank of Canada raised its target for the overnight rate by 25 basis points (bps) from 2.25% to 2.50% (with the Bank Rate moving to 2.75% and the Deposit Rate to 2.45%). This policy reversal represents the central bank's first rate movement since the 25 bps cut on October 29, 2025—ending a streak of seven consecutive rate holds—and marks the first monetary tightening hike since July 2023. Major Canadian chartered banks and wholesale monoline lenders adjusted the commercial Canadian Chartered Bank Prime Rate from 4.45% to 4.70% (effective Thursday, October 29, 2026, tracked under BoC statistical series V80691311, while TD Mortgage Prime moves from 4.60% to 4.85%).

What Did the Bank of Canada Decide on October 28, 2026?
On October 28, 2026, the Bank of Canada raised its target overnight interest rate by 25 basis points from 2.25 percent to 2.50 percent, marking its first rate hike since July 2023.
Entering the Wednesday, October 28, 2026 policy announcement and quarterly Monetary Policy Report (MPR), the Bank of Canada's overnight target rate had stood at 2.25% since October 29, 2025, following nine cumulative rate cuts from the July 2023 peak of 5.00% and seven consecutive rate holds between December 2025 and September 2026. While the C.D. Howe Institute's Monetary Policy Council voted 6-to-1 on October 22, 2026 to recommend holding the overnight rate at 2.25% through late 2026 before hiking to 2.50% in April 2027 and 2.75% by October 2027, overnight index swap (OIS) markets—pricing a 74% to 87% probability of a hike—and a Reuters poll of economists accurately anticipated the 25 bps tightening move to 2.50%.
Authored by Dallas Martin (Licensed Mortgage Agent Level 2, FSRA Licence #M17001133) at The Mortgage Firm (FSRA Brokerage Licence #13466), this actuarial and regulatory analysis breaks down the official October 2026 MPR inflation and GDP revisions, central bank operating band mechanics, Section 6 Interest Act payment math across official September 2026 LSTAR housing benchmarks, and immediate underwriting strategies for Southwestern Ontario buyers and renewing homeowners.
Why Did the Bank of Canada Hike Interest Rates to 2.50%?
The Bank of Canada raised rates to 2.50 percent because Canadian inflation rose to 3.2 percent in September 2026, driven by higher global energy prices that lifted the 2027 inflation forecast to 3.1 percent.
A forensic cross-examination of the Bank of Canada's official October 28, 2026 Monetary Policy Report (MPR) and Statistics Canada releases resolves a widely reported inflation discrepancy across pre-decision financial media. Several commentary outlets published prior to October 28 cited September 2026 annual headline CPI at 3.1% (up from 3.0% in August), while one competing mortgage blog erroneously cited headline inflation at 1.7% by confusing a sub-component with the all-items index. In reality, the Bank of Canada's official October 28, 2026 MPR confirms that annual headline CPI inflation reached 3.2% in September 2026, breaching the upper bound of the Bank's 1.0% to 3.0% target control range primarily due to surging global oil prices and energy-related transportation costs stemming from the Iran war and broader Middle East conflict.
Even though Statistics Canada's preferred core inflation gauges remained near the 2.0% midpoint in September 2026—with CPI-trim at 1.8%, CPI-median at 1.9%, CPI-common at 2.4%, and shelter inflation at 1.8% (rent +2.8%, mortgage interest cost index -0.2%)—Governor Tiff Macklem explicitly stated in his press conference that "the combination of higher energy prices and pass-through increases the persistence of inflation" and confirmed that Governing Council acted pre-emptively to prevent elevated energy costs from spilling over into generalized consumer inflation expectations.
| Bank of Canada Macroeconomic Indicator | July 2026 MPR Baseline | October 28, 2026 MPR Revision | Monetary Policy & Rate Trajectory Implication |
|---|---|---|---|
| September 2026 Headline CPI & Year-End 2026 Forecast | 3.0% (Aug) / 3.0% Year-EndProj. | 3.2% (Sep Actual) / 3.5% Year-End 2026 | Breaches 1%–3% target ceiling on Middle East energy pass-through |
| Annual 2027 CPI Inflation Forecast | 2.0% Annual Average | 3.1% Annual Average (+110 bps jump) | Inflation not expected to return near 2.0% target until mid-2028 |
| 2026 Canadian Real GDP Growth (Annual & Quarterly) | 0.7% Annual 2026 Forecast | 1.0% Annual (Q2: 3.3% | Q3: 2.0% | Q4: 0.8%) | Upgraded 2026 growth despite Q4 slowdown from new U.S. tariffs |
| 2027 & 2028 Real GDP Growth Forecasts | 1.8% (2027) / 1.8% (2028) | 2.0% (2027) / 2.0% (2028) | Resilient consumer spending, business investment & export recovery absorb slack |
| Forward Guidance & Next Scheduled Rate Date | 2.25% Neutral Floor | Dec 9, 2026 (9:45 AM ET) & Q1 2027 | Reuters poll (16/29 economists) & Oxford Economics project 2.75% by March 2027 |
Looking ahead, Governor Macklem cautioned that "there could be a need to increase the policy rate further, but given uncertainties, we will proceed carefully." A Reuters survey (16 of 29 economists) and Oxford Economics project an additional 25 bps hike to 2.75% by Q1 / March 2027. The final scheduled Bank of Canada rate announcement of 2026 will occur on Wednesday, December 9, 2026, at 9:45 AM ET (a rate-decision-only announcement not accompanied by an MPR).
What Is the New Prime Rate in Canada After the October 2026 Hike?
Following the Bank of Canada's quarter-point rate increase on October 28, 2026, the prime lending rate at major Canadian banks and wholesale mortgage lenders rose from 4.45 percent to 4.70 percent.
From a strict financial compliance standpoint, the Bank of Canada does not set or issue a "Bank of Canada Prime Rate." Instead, the central bank establishes three specific monetary policy rates that govern its operating band:
- The Overnight Rate Target (2.50%): Raised from 2.25% to 2.50% on October 28, 2026, serving as the midpoint policy benchmark for overnight interbank lending.
- The Bank Rate (2.75%): The upper bound of the operating band charged to commercial financial institutions for overnight Standing Liquidity Facility borrowing, set 25 bps above the overnight target and moving from 2.50% to 2.75%.
- The Deposit Rate (2.45%): Paid on settlement balances, set 5 bps below the overnight target under the 2026 regime and moving from 2.20% to 2.45%.
In contrast, the Canadian Chartered Bank Prime Rate—moving from 4.45% to 4.70% across the Big Six chartered banks (RBC, TD, BMO, Scotiabank, CIBC, and National Bank) and wholesale monoline lenders, while TD maintains a separate TD Mortgage Prime Rate moving from 4.60% to 4.85%—is an independent commercial benchmark set by private financial institutions (tracked by the Bank of Canada under statistical series V80691311). Consistent with the Bank of Canada's post-2021 rule, overnight rate changes take effect the business day after the announcement (Thursday, October 29, 2026).
How Much Does a 0.25% Rate Hike Increase Ontario Variable Mortgage Payments?
On a 25-year adjustable-rate mortgage in Ontario, the October 2026 quarter-point rate hike increases monthly mortgage payments by approximately 13 dollars and 61 cents for every 100,000 dollars of mortgage balance.
Under Section 6 of the federal Interest Act, Canadian mortgage amortization calculations require semi-annual compounding conversion to determine the effective monthly periodic interest rate (i_m) from a nominal annual contract rate (r_{ ext{nominal}}), followed by the standard level-payment formula over (n) monthly periods for principal balance (P):
1. Standard Wholesale Variable (Prime − 0.95%):• Pre-Hike 3.50% (Prime 4.45%): i_m = (1 + 0.0350/2)^(1/6) − 1 = 0.002895824 (0.2895824%/mo) ⟹ $499.27/mo per $100,000 (25-Yr, n=300) | $447.67/mo per $100,000 (30-Yr, n=360)• Post-Hike 3.75% (Prime 4.70%): i_m = (1 + 0.0375/2)^(1/6) − 1 = 0.003100858 (0.3100858%/mo) ⟹ $512.88/mo per $100,000 (+$13.61/mo or +$163.32/yr per $100k on 25-Yr) | $461.78/mo per $100,000 (+$14.11/mo per $100k on 30-Yr)2. High-Ratio Insured Variable (Prime − 1.00% on $550,000 Balance, 25-Yr):• Pre-Hike 3.45%: i_m = 0.002854672 ⟹ $2,735.12/mo (Saved $307.72/mo vs. 4.49% Fixed Insured @ $3,042.84/mo, i_m = 0.00370716)• Post-Hike 3.70%: i_m = 0.003059876 ⟹ $2,809.85/mo (+$74.73/mo or +$896.76/yr; still saves $232.99/mo or $2,795.88/yr vs. 4.49% Fixed!)
Across standard principal tiers at Prime − 0.95% over a 25-year amortization ((n = 300)), the pre-hike 3.50% payment of $499.27 per $100,000 translated to $1,997.08/mo on $400,000, $2,496.35/mo on $500,000, $2,571.25/mo on $515,000 (or $2,305.51/mo over a 30-year amortization), and $2,745.99/mo on $550,000. Under the post-hike 3.75% rate, those payments adjust by +$13.61/mo per $100,000 (or +$14.11/mo per $100,000 over 30 years).
Adjustable-Rate Mortgages (ARMs / VRMVP) vs. Static-Payment Variable Mortgages (VRMs / VRMFP) & Section 10 Penalty Math
How this +25 bps Prime rate adjustment hits your cash flow depends on your lender's contract structure:
- Adjustable-Rate Mortgages (ARMs / VRMVP)—originated by wholesale monoline lenders (MCAP, First National, CMLS, RMG), Scotiabank, and selective credit unions—experience the immediate +$13.61/mo per $100,000 payment adjustment while preserving their exact contractual amortization schedule.
- Variable-Rate Mortgages with Static Payments (VRMs / VRMFP)—originated by major retail banks such as RBC, TD, BMO, and CIBC—see no immediate change in monthly cash outlay, but the additional 25 bps of interest is deducted from principal repayment, extending effective amortization toward the contractual trigger rate boundary (R_{ ext{trigger}} = ( ext{Payment}_{ ext{periodic}} imes 12) / ext{Current Principal Balance}). You can calculate exact variable-rate mortgage trigger rate and conversion penalty math in our dedicated engineering guide.
- Section 10 Interest Act 3-Month Variable Prepayment Penalty: If a variable borrower elects to break their mortgage mid-term to switch lenders, Section 10 of the federal Interest Act caps the variable prepayment penalty at three months of simple interest, ( ext{Penalty}_{ ext{variable}} = ext{Balance} imes (R_{ ext{contract}} / 12) imes 3). A 25 bps hike increases that statutory penalty by only $62.50 per $100,000 of balance (for example, on a $550,000 insured balance, rising from $4,743.75 at 3.45% to $5,087.50 at 3.70%)—allowing you to understand how Big Bank Interest Rate Differential (IRD) penalties compare to 3 months' interest or evaluate the weighted-average blended rate math of a short-term second mortgage.

Do Fixed Mortgage Rates Change When the Bank of Canada Raises Rates?
Existing fixed-rate mortgage payments do not change mid-term. However, new Ontario five-year fixed rates track Government of Canada bond yields near 3.54 percent, keeping wholesale fixed rates near 4.49 to 4.64 percent.
While the Bank of Canada controls the overnight rate, fixed-rate mortgages in Ontario are priced off the 5-year Government of Canada (GoC) benchmark bond yield (Bank of Canada series BD.CDN.5YR.DQ.YLD). After surging to a 52-week high of 3.729% on September 28, 2026, the 5-year GoC bond yield traded near 3.50% to 3.54% in mid-to-late October 2026. Because institutional mortgage lenders require a 120 to 150 bps net interest margin over GoC bond yields to fund fixed mortgages, a 3.54% bond yield implies an equilibrium 5-year fixed retail rate of 4.74% to 5.04%.
Consequently, our current wholesale specials—4.49% 5-year fixed insured, 4.64% 5-year fixed conventional, and 4.39% 3-year fixed insured—represent urgent rate-protection windows before bond desks reprice upward. Active shoppers should immediately lock in a $0-fee 120-day wholesale rate hold at 4.49% insured or 4.64% conventional, compare the updated 2026 Ontario fixed vs. variable mortgage rate forecast, and activate an automated SMS or email rate drop alert via the NewLife Rate Watcher.
Beyond monthly payments, today's rate hike also compresses variable-rate purchasing power under the OSFI Guideline B-20 stress test, where the Minimum Qualifying Rate is defined as (r_{ ext{MQR}} = max(r_{ ext{contract}} + 2.00%, 5.25%)). Prior to October 28, a 3.50% variable rate qualified at 5.50%, offering a 114 bps underwriting advantage over the 4.64% conventional fixed rate (6.64% MQR). With the variable contract rate rising to 3.75%, the variable MQR jumps to 5.75%, narrowing the qualification spread against conventional fixed to 89 bps (and to 74 bps against the 6.49% insured fixed MQR) and reducing maximum variable borrowing capacity by approximately $14,500 to $16,500 across Southwestern Ontario. Eligible buyers can offset that compression by pairing a 30-year insured amortization with our FHSA and RRSP HBP down payment stacking guide (note that self-employed stated-income / bank statement programs always require a minimum 20% down payment / maximum 80% LTV).
