An American who acts like a Canadian (says 'eh' alot, watched the NHL, supports Canadian sports teams, says 'aboot', etc.) or an American who wants to live in Canada. The term comes from the belief that someone in this condition is believed to be in Canada or in the mind of a Canadian, thus an Am (American) is in the Can (Canada).
