Across Canada, Labour Day is a statutory (public) holiday that is observed on the first Monday in September. This year, Labour Day is September 5. Typically, employees are given Labour Day off with regular pay or public holiday pay (depending on the province or territory of employment). In the event employees are required to work on the holiday, the employee must be paid regular wages and get a substituted day off with pay at a later date (again, this depends on the province or territory of employment).
This year, Labour Day falls on Monday September 7, 2015. All provinces and territories in Canada observe this public holiday. Government bodies and agencies as well as many businesses are closed on Labour Day.
