Labour Day has been celebrated on the first Monday in September in Canada since the 1880s. The origins of Labour Day in Canada can be traced back to April 14, 1872 when a parade was staged in support of the Toronto Typographical Union's strike for a 58-hour work-week.[2] The Toronto Trades Assembly (TTA) called its 27 unions to demonstrate in support of the Typographical Union who had been on strike since March 25.[2] 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police to charge the Typographical Union with "conspiracy."[2] Although the laws criminalizing union activity were outdated and had already been abolished in Great Britain, they were still on books in Canada and police arrested 24 leaders of the Typographical Union. Labour leaders decided to call another similar demonstration on September 3 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.[2] Parliament passed the Trade Union Act on June 14 the following year, and soon all unions were demanding a 54-hour work-week.
