Labour Day (French: "Fête du Travail") has been marked as a statutory public holiday in Canada on the first Monday in September since 1894. However, the origins of Labour Day in Canada can be traced back to numerous local demonstrations and celebrations in earlier decades. Such events assumed political significance in 1872, when a labour demonstration in Toronto in April 1872, in support of striking printers, led directly to the enactment of the Trade Union Act, a law that confirmed the legality of unions. Ten years later, on 22 July 1882, a huge labour celebration in Toronto attracted the attention of the American labour leader Peter J. McGuire, who organized a similar parade in New York City on 5 September that year. Unions associated with the Knights of Labor and the American Federation of Labor in both Canada and the United States subsequently promoted parades and festivals on the first Monday in September. In Canada, local celebrations took place in Hamilton, Oshawa, Montreal, St Catharines, Halifax, Ottawa, Vancouver and London during these years. Montreal declared a civic holiday in 1889. In Nova Scotia, coal miners had been holding picnics and parades since 1880 to celebrate the anniversary of their union, the Provincial Workmen's Association, first organized in 1879. In addition, in 1889, the Royal Commission on the Relations of Labor and Capital in Canada recommended recognition of an official "labour day" by the federal government. In March and April 1894 unions lobbied Parliament to recognize Labour Day as a public holiday. Legislation was introduced in May by Prime Minister Sir John Thompson and received royal assent in July 1894.
