Labour Day (French: Fête du Travail) has been celebrated in Canada on the first Monday in September since the 1880s. The origins of Labour Day in Canada can be traced back to December 1872 when a parade was staged in support of the Toronto Typographical Union's strike for a 58-hour work-week, almost a full decade before a similar event in New York City by the American Knights of Labor, a late 19th-century U.S. labor federation, launched the movement towards the American Labor Day holiday. The Toronto Trades Assembly (TTA) called its 27 unions to demonstrate in support of the Typographical Union who had been on strike since 25 March. George Brown, Canadian politician and editor of the Toronto Globe hit back at his striking employees, pressing police to charge the Typographical Union with "conspiracy." Although the laws criminalising union activity were outdated and had already been abolished in Great Britain, they were still on the books in Canada and police arrested 24 leaders of the Typographical Union. Labour leaders decided to call another similar demonstration on 3 September to protest the arrests. Seven unions marched in Ottawa, prompting a promise by Canadian Prime Minister Sir John A. Macdonald to repeal the "barbarous" anti-union laws. Parliament passed the Trade Union Act on 14 June the following year, and soon all unions were seeking a 54-hour work-week.
The Toronto Trades and Labour Council (successor to the TTA) held similar celebrations every spring. American Peter J. McGuire, co-founder of the American Federation of Labor, was asked to speak at a labour festival in Toronto, Ontario, Canada on 22 July 1882. Returning to the United States, McGuire and the Knights of Labor organised a similar parade based on the Canadian event on 5 September 1882 in New York City, USA. On 23 July 1894, Canadian Prime Minister John Thompson and his government made Labour Day, to be held in September, an official holiday. In the United States, the New York parade became an annual event that year, and in 1894 was adopted by American president Grover Cleveland to compete with International Workers' Day (May Day).
While Labour Day parades and picnics are organised by unions, many Canadians regard Labour Day as the Monday of the last long weekend of summer. Non-union celebrations include picnics, fireworks displays, water activities, and public art events. Since the new school year generally starts right after Labour Day, families with school-age children take it as the last chance to travel before the end of summer.
An old fashioned tradition in Canada and the United States frowns upon the wearing of white after Labour Day. Explanations for this tradition vary; the most common is that white is a summer colour and Labour Day unofficially marks the end of summer. The rule may have been intended as a status symbol for new members of the upper and middle classes in the late 19th and early 20th century.
A Labour Day tradition in Atlantic Canada is the Wharf Rat Rally in Digby, Nova Scotia, while the rest of Canada watches the Labour Day Classic, a Canadian Football League event where rivals like Calgary Stampeders and Edmonton Eskimos, Hamilton Tiger-Cats and Toronto Argonauts (except in 2011 and 2013, due to scheduling conflicts), and Saskatchewan Roughriders and Winnipeg Blue Bombers play on Labour Day weekend. Before the demise of the Ottawa Renegades after the 2005 season, that team played the nearby Montreal Alouettes on Labour Day weekend. Since the 2014 CFL season, when the Ottawa Redblacks began play, the Montreal–Ottawa Labour Day tradition has once again been observed. Likewise, Ontario University Athletics has a long-established tradition to play university football on Labour Day.
The Labour Day parade in Grand Falls-Windsor, Newfoundland started in 1921 and still continues today, over 90 years later. The celebrations go on for three days with a parade on Labour Day Monday.
