In 1968, Pearson was succeeded by Pierre Trudeau, who also advocated patriation. He made several attempts, including the Victoria Charter in 1971 and more proposed amendments in 1978. At the 1978–1979 conference, Trudeau prepared for the first time to provide some federal concessions with regard to the division of powers, including family law, fisheries, and resources. However, the other premiers balked, which led to speculation they were waiting to see if the more province-friendly Progressive Conservatives would win the coming federal election. In that campaign, the Liberals ran on constitutional change, including a speech at Maple Leaf Gardens in which Trudeau promised unilateral action if the premiers did not agree to patriation.
