The National Day of Mourning, or Workers’ Mourning Day, originated in Canada in 1984 and is now observed annually in over 100 countries on April 28 to honour the memory of those who have died, and pay respect to those who have been adversely affected by life-changing injuries or illnesses in the workplace (read more). The PEI Federation of Labour will host a National Day of Mourning Ceremony on Sunday, April 28, 2019 at 2:00 pm at St Paul's Church Hall, 101 Prince Street, Charlottetown. The University of Prince Edward Island will observe the day by keeping the flags at half-mast (they were lowered earlier this week to honour UPEI alumnus Josh Underhay and his son Oliver who passed away suddenly as a result of a tragic accident).
