Ontario's Minimum Wage Rose to $17.60 on October 1, 2025: What Toronto Employers Need in Their Payroll Now

Ontario's general minimum wage moved from $17.20 to $17.60 an hour on October 1, 2025 — a $0.40, 2.4 percent increase tied to the Ontario Consumer Price Index under the Employment Standards Act's annual adjustment formula. For Toronto-area employers, the headline number is only part of the story: three of Ontario's specialized minimum wage rates moved with it on the same date, and the increase landed in a year when U.S. tariffs were already pressuring margins for many small and mid-sized employers. This is what actually changed on October 1, and what to check in your payroll now that the new pay periods are underway.

The October 1, 2025 rates, in detail

Ontario reviews its minimum wage rates annually under the Employment Standards Act. Any change is tied to the Ontario CPI and takes effect October 1, running through September 30 of the following year. For the period October 1, 2025 to September 30, 2026, the confirmed rates are:

The student minimum wage applies to employees under 18 who work 28 hours a week or less while school is in session, or who work during a school break or summer holidays. The homeworkers' rate applies to employees who do paid work out of their own home for an employer, a category that has grown alongside remote and gig-adjacent arrangements in the GTA. Both moved by roughly the same dollar amount as the general rate, so payroll systems that hard-code the general minimum wage without a linked update to these sub-rates will understate what's owed to any employee in those categories.

Why this is not a "set it and forget it" change

An October 1 effective date sits mid-fiscal-year for most Toronto businesses, which means the increase does not arrive as a clean line in a January budget — it lands mid-pay-period for anyone on a biweekly or semi-monthly cycle that straddles October 1, and it interacts with wage compression above the new floor.

Two mechanical points worth checking directly, not assuming:

1. Pay-period timing. Employees must be paid at least the new minimum for every hour worked on or after October 1, even if that falls in the middle of an existing pay period. A biweekly period running September 22 to October 5, for example, needs the old rate for hours worked through September 30 and the new rate for hours worked October 1 onward — unless your payroll provider applies the higher rate to the whole period by default, which most do, but it is worth confirming rather than assuming.
2. Compression above $17.60. Staff who were earning $17.60 to roughly $19 an hour under the old rate schedule are now earning at or barely above the new floor. If your pay grid was built around the $17.20 minimum, the differential between your lowest-paid and next-tier staff has narrowed by up to $0.40 without anyone getting an intentional raise. Employers who ignore this tend to see it resurface as a retention problem months later.

Two other 2025 cost lines moved at the same time

Toronto employers budgeting around the October wage change should also account for two changes already in force through the rest of 2025:

• Employer Health Tax (EHT). The EHT exemption for eligible private-sector employers (or associated groups of employers, who share one exemption) remains at $1,000,000 of total Ontario payroll, with no exemption once an employer's payroll passes $5,000,000. This threshold does not move with the minimum wage — a payroll increase driven by the wage hike is only relevant to your EHT exposure once your total Ontario payroll crosses the exemption on its own. See our Ontario Employer Health Tax guide for the full mechanics, and our employer payroll cost calculator to model the combined effect of the wage increase and EHT.
• HST on payroll services. Ontario's 13% HST applies to most payroll processing and bookkeeping services purchased to manage this transition, and is recoverable for HST-registered businesses — a detail worth confirming with whoever handles your input tax credits if you're bringing on new payroll support around the change.

A practical checklist for Toronto-area employers

• Confirm every hourly role is at or above $17.60, and specifically check any employee paid $17.20–$17.60 under the old schedule — these must move, with no grace period.
• Update student, homeworker, and guide sub-minimums separately if your payroll system does not link them automatically to the general rate.
• Map the compression band above $17.60 and decide, deliberately, whether to preserve pay differentials for staff just above the new floor rather than letting the gap erode silently.
• Check the pay period straddling October 1 was calculated correctly, not assumed correct by default.
• Reconcile total 2025 Ontario payroll against the $1,000,000 EHT exemption if the wage increase pushes your payroll meaningfully higher this year.

What Toronto-area business owners should do next

If you run payroll in-house, the immediate task is a one-time audit: pull every hourly rate below $17.95 (to catch anyone who might already be below the next October 2026 rate as you plan ahead) and confirm the October 1, 2025 transition applied correctly to the pay period it fell in. If a bookkeeping and payroll provider handles this for you, ask them directly whether the sub-minimum rates for students and homeworkers were updated, since these are the categories most often missed in a general-rate-only update. For a business with staff clustered near the new floor, this is also a natural moment to decide — before the next annual adjustment — whether to build a small buffer above minimum wage into your pay grid, rather than reacting to each October increase individually.

Key takeaways

• Ontario's general minimum wage rose from $17.20 to $17.60 on October 1, 2025 (+2.4%), with student, homeworker, and guide sub-minimums increasing by similar amounts on the same date.
• The student rate is now $16.60/hour and the homeworkers' rate is now $19.35/hour — both easy to miss if payroll only tracks the general minimum.
• Check the pay period that straddled October 1 for correct rate application, and map wage compression above $17.60 before it becomes a retention issue.
• The EHT $1,000,000 exemption is unchanged and does not move with the minimum wage — only your total payroll growth affects your EHT exposure.
• Ontario's next scheduled minimum wage increase brings the general rate to $17.95 on October 1, 2026 — worth planning for now if your pay grid is still being rebuilt after this year's change.
