In most countries of the world the Labor Day May 1, however in Canada is commemorated the first Monday in September of each year.
The origins of Labor Day in Canada date back to December 1872, when a march in support of the Toronto letterpress industry strike was organized for a worker who has 58 hours of work in the workweek.
In this way, the Union of Typographers, which had been on strike since March 25, organized a paralysis which caused the police to arrest 24 leaders of the Union of Typographers. Then seven other unions demonstrated in Ottawa, prompting a promise by Canadian Prime Minister Sir John A. Macdonald to repeal "barbaric" anti-union laws.
Until Parliament passed the law on unions on June 14 of the following year, and soon all unions demanded 54 hours a work week. On July 23, 1894, Canadian Prime Minister John Thompson and his government approved Labor Day to be observed in September, an official holiday.
While Labor Day parades and picnics are organized by the unions, many Canadians have picnics, fireworks shows, water activities, and public art events. Since the new school year generally begins after Labor Day, families with school-age children take it as the last chance to travel before the end of summer.
It should be noted that there is a Labor Day parade in Grand Falls-Windsor, Newfoundland, which began in 1910 and continues today, where the celebrations continue for three days with the Labor Day parade on Monday.
