 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."
