April 28

Workers' Memorial Day and the World Day for Safety and Health at Work are observed on April 28 each year to remember those affected by workplace accidents and occupational diseases. Established by the International Labour Organization, these observances encourage governments, employers, and workers to prioritize safety and health standards. Activities include memorial services, workshops, and campaigns to raise awareness about risk prevention and safe working conditions. In Canada, the day is also recognized as the National Day of Mourning with ceremonies at graveyards and workplaces. The goal is to drive improvements in legislation and enforcement to ensure safer workplaces worldwide.

National Day of Mourning in Canada is a solemn observance held annually on April 28 to honor workers who have been killed, injured, or suffered illnesses due to workplace hazards. It coincides with International Workers' Memorial Day and serves as a reminder of the human cost of occupational accidents. Established by the Canadian Labour Congress, this day urges employers, governments, and individuals to renew efforts in promoting workplace health and safety. Ceremonies nationwide include moments of silence, wreath-laying at memorials, and educational events. The day also highlights ongoing campaigns to strengthen labour protections and prevent future tragedies.
