Ontario Business Day Calculator
Last reviewed: October 14, 2026 · Holiday data: October 7, 2026
Calculate business days in Ontario with its own statutory holidays. Like the Canada calculator, this page counts Monday to Friday as working days; what changes is the holiday list, so due dates and deadlines can land differently from the federal count.
How Ontario differs from the federal Canadian holidays
The Ontario guide to the Employment Standards Act lists nine public holidays: New Year's Day, Family Day, Good Friday, Victoria Day, Canada Day, Labour Day, Thanksgiving Day, Christmas Day and Boxing Day (26 December). Against the federal Canadian set that adds Family Day and leaves out the National Day for Truth and Reconciliation and Remembrance Day, so a count on Ontario's calendar drops those two. The guide adds that an employer who gives Easter Monday, the first Monday in August or Remembrance Day off is not required to by the Act. When a public holiday falls on a day an employee would not ordinarily work, the employee gets a substitute day off no later than three months after the holiday, or up to 12 months after it if the employee has agreed electronically or in writing, or public holiday pay instead if the employee agrees to that electronically or in writing. The guide names no date for the substitute day, so this calendar counts none: a public holiday on a Saturday or Sunday stays on its own date and no weekday is added for it.
Worked example
Adding 2 business days to Friday, February 13, 2026 using Ontario's statutory holidays lands on Wednesday, February 18, 2026. With the federal Canadian holidays, the same calculation lands on Tuesday, February 17, 2026: the gap comes from Ontario's own calendar.

How to count Ontario business days
For an interactive calculation, use the Canada calculator, which counts the federal holidays. Under Advanced options you can add any dates Ontario adds to the federal set, one per line, in the year-month-day form shown there. Advanced options cannot remove a date, so a count that crosses a weekday the federal set closes and Ontario's calendar leaves open will not match Ontario's calendar. The Ontario statutory holidays 2026 page linked below lists the dates.
Ontario statutory holiday data is verified against the Ontario Employment Standards Act guide (ontario.ca).
