Events are planned to remember those who lost their lives or were injured at work.
The National Day of Mourning commemorates workers who have been killed, injured or suffered illness due to workplace related hazards or occupational exposures.
The observance began in 1984 and it was officially declared an annual day of remembrance the following year by the Canadian Labour Congress.
In 1991, the day became a national observance when the Workers’ Mourning Day Act was passed, making April 28 an official Workers’ Mourning Day.
It is observed in more than 100 countries around the world.
Many stories are resurfacing about the Westray Mine Disaster this year.
Next month marks 30 years since the tragedy in Pictou County when 26 miners were killed in an underground explosion.
A moment of silence will be held at 11:00 a.m. to remember those killed on the job.
