A number of organizations were formed to oppose the reciprocity agreement of January 1911 between Canada and the US. Most prominent was the Canadian National League, headed by Toronto lawyer Zebulon Lash. Others were the Canadian Home Market Association, a branch of the Canadian Manufacturers' Association which was active in distributing propaganda literature and in raising funds for the campaign; and the Anti-Reciprocity League, established in Montréal in late February. Claiming to be politically nonpartisan, this league launched a door-to-door petition campaign and held rallies throughout the country. A leading figure in the anti-reciprocity agitation was Clifford Sifton, formerly minister of the interior in the Liberal government.
