Remembrance Day – also known as Poppy Day or Armistice Day (the event it commemorates) or Veterans Day – is a Commonwealth holiday to commemorate the sacrifices of members of the armed forces and of civilians in times of war, specifically since the First World War. It is observed on 11 November to recall the end of World War I on that date in 1918 (major hostilities of World War I were formally ended “at the 11th hour of the 11th day of the 11th month” of 1918 with the German signing of the Armistice).
The poppy’s significance to Remembrance Day is a result of Canadian military physician John McCrae’s poem In Flanders Fields. The poppy emblem was chosen because of the poppies that bloomed across some of the worst battlefields of Flanders in World War I, their red colour an appropriate symbol for the bloodshed of trench warfare. A Frenchwoman, Anna E. Guérin, introduced the widely used artificial poppies given out today.
In Canada, Remembrance Day is a public holiday in all provinces and territories except Ontario, Quebec and Manitoba.
