Ontario Business Day Calculator
Last reviewed: May 19, 2026 · Holiday data: June 24, 2026
Calculate business days in Ontario with its own statutory holidays. Ontario shares the Monday to Friday working week and the Saturday and Sunday weekend with the rest of Canada, but its statutory holiday calendar is different, so due dates and deadlines can land differently from the federal count.
How Ontario differs from the federal Canadian holidays
Ontario follows the federal Canadian holidays but runs its own statutory list under the Employment Standards Act. It adds Family Day on the third Monday of February and does not treat Easter Monday, the National Day for Truth and Reconciliation (30 September), or Remembrance Day (11 November) as provincial public holidays, so a count built on Ontario's statutory calendar drops those three. The Civic Holiday on the first Monday of August (Simcoe Day in Toronto) is widely observed but optional, not an Employment Standards Act public holiday, so it is left out of the statutory count. The working week is Monday to Friday with a Saturday and Sunday weekend.
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.
