National Day of Mourning
“A day to remember those killed or seriously injured in the workplace.
On Day of Mourning, April 28, all who care deeply about workplace tragedy stand together to honour those affected and to recommit to safer and healthier workplaces. “
How workers and families honour their losses
Day of Mourning is an important day for Threads of Life members – a time for private remembrance, but also a time when many choose to share their personal stories in order to honour their loved ones and their own experience, and to help others understand the impact of a death, serious injury or illness caused simply by going to work. If you are personally affected by tragedy, you can join our virtual ceremony on April 28, find a public ceremony to attend through our list below, or visit our Facebook page on Day of Mourning to share your experience or your loved one’s name.
How to get involved
April 28th is a Day of Mourning for all of us, even if we’re not affected personally. We all miss out on the contributions of thousands of Canadians injured or killed at work. That’s why it’s so important to pause and reflect on those losses.

In 1984, unions in Sudbury, Ontario, adopted the day to publicly acknowledge workplace injuries, illnesses, and deaths. The Canadian Labour Congress held its first day of remembrance in 1986. The date of April 28th was chosen to reflect the day Ontario passed the Workers’ Compensation Act in 1914.
National Day of Mourning
Canada recognized its first National Day of Mourning for Persons Killed or Injured in the Workplace on April 28, 1991. On this day, flags fly at half-mast, and ceremonies across the country recognize the lives needlessly lost to workplace tragedy. More than 100 other countries have since adopted the observance known widely as Workers’ Memorial Day.
Day of Mourning Ceremonies and Tributes
Communities across the country hold in person Day of Mourning ceremonies. Join with others, in person or at Threads of Life’s online ceremony to honour lives forever changed, and renew your commitment to workplace health and safety.
