The National Day of Mourning is observed in Canada on 28 April. It commemorates workers who have been killed, injured or suffered illness due to workplace related hazards and incidents.

Workers’ Memorial Day was started by the Canadian Union of Public Employees (CUPE) in 1984, and the Canadian Labour Congress officially declared it an annual day of remembrance in 1985 on April 28. In December 1990, this day became a national observance with the passing of the Workers Mourning Day Act, so that on April 28, 1991, it was officially the National Day of Mourning for persons killed or injured in the workplace; making April 28, an official Workers’ Mourning Day.
