National Day of Mourning – April 28

A day set aside each year to remember those who have been killed or seriously injured in the workplace.

Now an international observance as a day of mourning for workers killed, injured or made ill by their job, the declaration of April 28th as the Day of Mourning began here in Canada. In 1984, unions in Sudbury, Ontario, adopted the day as one to publicly acknowledge workplace injuries, illnesses, and deaths, and the Canadian Labour Congress officially declared the day of remembrance. The date of April 28th was chosen to reflect the anniversary of the day Ontario passed the Workers’ Compensation Act in 1914.

On April 28, 1991, Canada recognized its first National Day of Mourning for Persons Killed or Injured in the Workplace: a day where flags fly at half-mast, and we hold ceremonies across the country to recognize the lives needlessly lost, and the tremendous suffering of those left in the wake of workplace tragedy. In the years since, more than 100 other countries have also adopted the observance known widely as Workers’ Memorial Day.

On April 28, join one of the hundreds of ceremonies across the country, or light your own candle in honour and reflection of the thousands of lives forever changed, and to renew your commitment to workplace health and safety – and ending such needless suffering.

Marking the Day of Mourning

Each of our family members experiences Day of Mourning differently. Some may not be able to attend a ceremony every year if they have to work that day. Some may attend a ceremony alone, while others couldn’t imagine attending without their family and friends. Some (our volunteer speakers) may be sharing their story at a ceremony, while others choose to share memories with loved ones only. We asked three of our family members to share with us what Day of Mourning means to them. Here’s what they had to say.

A truly international Day of Mourning

It is time for a vacation. For several years we have discussed going on a cruise with our close friends. We finally made that happen. The decision to take a Panama Canal cruise seemed like a good idea and we investigated options and made our choices. There were several ports in different countries and we had to sort through options for day tours. They all sounded so exciting, with new things to see and do.
