The 28th of April is International Commemoration Day for Dead and Injured Workers organized worldwide by the trade union movement since 1996. 

The Canadian Centre for Occupational Health and Safety (CCOHS) reminds us that the National Day of Mourning, April 28, is not only a day to remember and honour those lives lost or injured due to a workplace tragedy, but also a day to renew the commitment to improve health and safety in the workplace and prevent further injuries, illnesses, and deaths.
