The Trades and Labor Congress of Canada was a Canada-wide central federation of trade unions from 1886 to 1956. It was founded at the initiative of the Toronto Trades and Labour Council and the Knights of Labor. It was the third attempt at a national labour federation to be formed in Canada: it succeeded the Canadian Labour Union which existed from 1873 to 1877 and the Canadian Labour Congress which held only one conference in 1881.

The American Federation of Labor was a national federation of labor unions in the United States that continues today as the AFL–CIO. It was founded in Columbus, Ohio, in 1886 by an alliance of craft unions eager to provide mutual support and disappointed in the Knights of Labor. Samuel Gompers was elected the full-time president at its founding convention and was re-elected every year except one until his death in 1924. He became the major spokesperson for the union movement.
