If you run an hourly crew in Oshawa, Whitby or Ajax, 1 October 2026 is on your payroll calendar whether you have added it or not. The Ontario minimum wage rate rises to $17.95 an hour that day, and the change carries three payroll rules that quietly cost employers money when they get missed. Here is what actually changes, what it costs per employee, and the one Employment Standards Act rule most owners get wrong on the pay period that straddles the increase.
Key takeaways
- From 1 October 2026, the Ontario minimum wage is $17.95 an hour, up from $17.60 per hour. The student minimum wage rises to $16.90 from $16.60. The homeworkers minimum wage rises to $19.70 from $19.35.
- If your pay period straddles 1 October 2026, the ESA treats it as two separate pay periods. Hours worked before 1 October are paid at $17.60, hours worked on or after 1 October are paid at $17.95, on the same cheque.
- The straight annual cost of the increase for one employee working 40 hours per week is about $728 a year in wages, before CPP, EI and Employer Health Tax gross-up.
- The three-hour rule now costs $53.85 per triggered shift at the general minimum wage, up from $52.80. Sending staff home short adds up faster than the rate change itself.
- Hunting, fishing and wilderness guides move to $89.75 for a day under five hours and $179.50 for a day of five or more hours. This one matters for Uxbridge and Port Perry outfitters, not for downtown Oshawa.
The new Ontario minimum wage rate on 1 October 2026
Ontario indexes the provincial minimum wage to the Ontario Consumer Price Index each year. The 2026 annual increase was announced by the Ontario government on 1 April 2026 and takes effect 1 October 2026, per the Ontario ESA minimum wage guide. Every rate in the table below comes from that page.
| Category | Rate to 30 September 2026 | Rate from 1 October 2026 | Change |
|---|---|---|---|
| General minimum wage | $17.60 per hour | $17.95 per hour | +$0.35 |
| Student minimum wage (under 18, up to 28 hours/week when school is in session) | $16.60 per hour | $16.90 per hour | +$0.30 |
| Homeworkers minimum wage | $19.35 per hour | $19.70 per hour | +$0.35 |
| Hunting, fishing and wilderness guides (under 5 hrs/day) | $88.05 | $89.75 | +$1.70 |
| Hunting, fishing and wilderness guides (5+ hrs/day) | $176.15 | $179.50 | +$3.35 |
For context, the previous general minimum wage rate before that was $17.20 per hour (1 October 2024 to 30 September 2025). The 2026 general minimum wage rate of $17.95 sits above the federal minimum wage of $18.15 an hour only for federally regulated employers (banks, telecom, interprovincial transport); every other Ontario employer applies the provincial minimum wage. There is no separate liquor server minimum wage: that category was folded into the general rate on 1 January 2022.
The pay-period rule most employers get wrong
Here is the rule most payroll systems can handle but most owners still input wrong. Under the Employment Standards Act, if a pay period spans a minimum wage change, the ESA treats it as if it were two separate pay periods, and each half must be paid at the applicable minimum wage.
For a bi-weekly pay period running Monday 21 September to Sunday 4 October 2026, an employee's cheque covers:
- Hours worked 21 to 30 September at $17.60 per hour (the current minimum wage until 30 September).
- Hours worked 1 to 4 October at $17.95 per hour (the new minimum wage effective 1 October).
Both blocks appear on the same pay stub. The two rates are not averaged, and you cannot pay the full pay period at the old rate and top up later. The Ministry of Labour's compliance test is: was each hour paid at the minimum wage that was in force when it was worked?
If your payroll software is set to a single rate per employee, the safest option is to update the default rate with an effective date of 1 October 2026 before running the September 30 payroll cycle. QuickBooks Online Payroll, ADP WorkforceNow, Wagepoint and Ceridian Dayforce all handle the split correctly when the rate change is dated. Bookkeepers running an off-the-shelf spreadsheet payroll for a small storefront often miss the split, which is where the ESA complaint usually starts.
A Durham Region example: what this costs a Whitby cafe
Take a fictional but realistic Whitby cafe on Dundas Street with four hourly baristas, each scheduled for 30 hours a week at the general minimum wage.
Weekly wage bill before 1 October 2026: 4 employees × 30 hours × $17.60 per hour = $2,112 a week.
Weekly wage bill from 1 October 2026: 4 employees × 30 hours × $17.95 per hour = $2,154 a week.
Straight rate change: $42 a week, or about $2,184 a year for the four-person crew. Add roughly 12% for CPP, EI and Employer Health Tax gross-up (CPP at 5.95%, EI at 2.28% employer share, EHT at about 1.95% once payroll clears the exemption, plus WSIB), and the true annual increase is closer to $2,446 for the crew, or about $611 per employee.
Now layer in the three-hour rule. The ESA requires that a worker whose regular shift is longer than three hours but who is sent home short must be paid the higher of the hours worked or three hours at their regular rate. At $17.95, one triggered shift now costs $53.85 in paid but unworked time, up from $52.80. If the cafe over-schedules a slow Tuesday and sends one barista home after 90 minutes twice a month, the three-hour rule now costs the business about $36 more a year than it did in September, before you count the wage change on the hours actually worked.
The lesson for a Whitby retail or hospitality employer: the payroll cost of the 1 October change is real but manageable at the crew level. Three-hour rule exposure grows in step with the minimum wage rate, and is the line item worth reviewing before 1 October, because it is the one you can control with a scheduling tweak.
What Durham Region employers should do before 1 October 2026
Six items belong on your list this September:
- Update the default hourly wage for every minimum-wage employee in your payroll system with an effective date of 1 October 2026. Do not backdate.
- Check every pay period that straddles 1 October 2026 for the split-rate treatment. If your pay periods are semi-monthly ending 15/30, the second September cycle runs 16 to 30 September (no split needed) and the first October cycle runs 1 to 15 October (all at the new rate). If your pay periods are bi-weekly or weekly on a Sunday-to-Saturday cycle, at least one cycle will straddle the change and needs the split.
- Post the updated ESA minimum wage poster where employees see it. The Ministry of Labour publishes it free at ontario.ca.
- Review your schedule for three-hour rule exposure. Employees whose regular shift is more than three hours but who occasionally get sent home short trigger the rule. Every triggered shift now costs $53.85 at the general minimum wage.
- Recheck any employee near the new minimum wage. A worker earning $18.00 was 40 cents above minimum in September and 5 cents above in October. That is not a legal problem, but it is a retention and morale one.
- Confirm your bookkeeping records the change as a rate change on 1 October rather than a raise. This matters for T4 categorization and payroll journal entries at year-end.
Employers running payroll in-house across multiple Durham locations, or splitting labour costs across an Oshawa office and a Whitby storefront, benefit from a pre-October payroll and bookkeeping review to catch the split-rate treatment in the crossover pay period.
FAQ
Does the 1 October 2026 minimum wage increase apply to salaried employees?
The ESA minimum wage test applies on a pay-period basis regardless of how someone is paid. For a salaried employee, divide the pay-period salary by the pay-period hours; the result must be at least $17.95 per hour from 1 October 2026. A salaried employee paid $700 a week for working 40 hours per week is at $17.50 an hour and falls below the new minimum wage. Most salaried professional roles are well above minimum wage and see no change.
What is the student minimum wage in Ontario for 2026, and who qualifies?
The Ontario student minimum wage 2026 rate is $16.90 per hour from 1 October, up from $16.60 per hour. The student rate applies to students under 18 who work 28 hours a week or less while school is in session, or who work during a school break such as March break or the summer holidays. A student who works more than 28 hours in a week during a school term is entitled to the general minimum wage of $17.95 for that week.
What happens on a pay period that straddles 1 October 2026?
The ESA treats the pay period as two separate pay periods. Hours worked before 1 October 2026 are paid at $17.60 per hour (the current minimum wage). Hours worked on or after 1 October are paid at $17.95 per hour (the new minimum wage). Both blocks appear on the same pay cheque, and the two rates are not averaged. The Ministry of Labour's compliance test is: was each hour paid at the minimum wage rate that was in force when it was worked?
How does the three-hour rule interact with the new minimum wage rate?
The three-hour rule requires that an employee whose regular shift is more than three hours and who is sent home short must be paid at least three hours at their regular rate. At the new $17.95 general minimum wage, one triggered shift now costs $53.85, up from $52.80. The rule does not apply to employees whose regular shift is three hours or less, or where the reason the shift ran short was beyond the employer's control.
