More than two workers die each and every day in Canada.
The tragic losses caused by deaths, injuries and illnesses that have occurred in workplaces will be recognized at Friday night's Day of Mourning ceremony.
Spokesperson John Millholland has witnessed the impact it has on families.
"Fortunately for myself it's never happened to anybody in my family and in none of my workplaces, but I've seen what it can do to other peoples," says Millholland. "Whether it be occupational disease, immediate injuries or death in the workplace -- I've seen the affect it has on families and it's just not nice at all."
He says paying tribute to those lost lives and committing to the prevention of future occupational injuries and diseases is somewhat therapeutic for people.
"It helps people to remember and helps people also to move on and realize that there's a fight that needs to be continued."
Millholland says they'll be recognizing the 25th anniversary of the devastating Westray coal mine explosion.
The death of 26 Nova Scotia miners on May 9, 1992, led to the creation of the Westray Law which holds managers and directors of corporations to account for failure to protect workers lives.
The ceremony, in the Firefighter Memorial Garden at Sarnia's Clifford Hansen Fire Station on East St. N, begins at 6pm.
