The largest cross-country umbrella coalition is the Canadian Peace Alliance, whose 140 member groups include large city-based coalitions, small grassroots groups, national and local unions, faith, environmental, and student groups, with a combined membership of over 4 million Canadians. The Canadian Peace Alliance has been a leading voice, along with its member groups opposing the "War on Terror". In particular, the CPA opposes Canada's participation in the war in Afghanistan and Canadian complicity in what it views as misguided and destructive U.S. foreign policy.
