anada's improved economy continued to impact upon the success of the labour movement. In the last four decades of the twentieth century, workers and their unions were forced to deal with long periods of recession and high inflation. Many unions faced a decline in membership, and victories for the labour movement were less frequent. Furthermore, new legislation, such as Prime Minister Pierre Trudeau's wage and price controls, actually reversed some of the movement's earlier gains. Nevertheless, while unions in the United States suffered serious setbacks in the last half of the century, Canadian unions, particularly in Quebec, continued to battle aggressively on behalf of the labour movement.
