In 2002 more than 900 people died in Canada as a result of work-related accidents or illnesses. This means that, on average, close to four workers are killed every working day. Close to 360,000 others were injured seriously enough to prevent them from reporting to work for at least one day. It is estimated that over one million work-related injuries and illnesses are reported each year in Canada.More at the Teamsters Canada Rail Conference website. Also, here's a link to CLC President Ken Georgetti's Day of Mourning statement.
In 2002 workers in all age groups under 50 years were equally likely to be injured while on the job. For the same year, the number of time-loss work-related injuries for men was also more than twice that for women.
Work-related accidents are very expensive. The total of compensation paid to work accident victims or their families and of other economic costs of work-related injuries each year are estimated at more than $12 billion. These figures do not take into account the pain and suffering of the victims and their families, which are incalculable.
Edit: It's been pointed out to me that the Workers Mourning Day Act was moved by NDP MP Rod Murphy (Churchill). And since I'm so darn partisan, I figured I might as well tip the ol' hat.
