April 28 is the National Day of Mourning—a day dedicated to honouring workers who lost their lives due to work-related illnesses or injuries. Every loss has a profound impact on families, friends, employers, co-workers and communities. Lives forever changed. In 2025, 144 Canadians passed away from work-related illness or injury.
