Lambert was re-elected in Edmonton, the Progressive Conservative government lost the election, and Lambert's two-month career as a cabinet minister came to an end. With the Conservatives in Opposition, Lambert sided with Diefenbaker's critics, and refused to sign a petition declaring loyalty to the Conservative leader in 1966 when Dalton Camp attempted to force a leadership review. In Opposition, Lambert was a leading critic in the areas of National Defence and Finance. During the short-lived government of Joe Clark, he was chairman of the Miscellaneous Estimates Committee, and led it through a flurry of activity. After being defeated in a bitter nomination race by his eventual successor, Murray Dorin, Lambert retired from the House of Commons at the 1984 election. He was appointed to the Canadian Transportation Commission by Prime Minister Brian Mulroney following the election. Archives There is a Marcel Lambert fonds at Library and Archives Canada.
