In an interview with CTV on Wednesday, the former Conservative prime minister reached back over 60 years to chide Trudeau for his antiwar activism as a university student, saying his refusal to serve in the Second World War rendered him unfit to provide moral leadership.
Mulroney blamed Trudeau for scuttling the Meech Lake accord, a 1990 pact aimed at securing Quebec's signature on the Constitution. He then launched into a diatribe about what he called a lack of moral fibre shown in Trudeau's opposition to the Second World War.
When he retired in 1993, Mulroney was one of the most reviled prime ministers in Canadian history. The late Trudeau, who retired as Liberal prime minister in 1984, is accorded more respect and admiration than Mulroney by Canadians in opinion polls.
Who do you think was the better Prime Minister and why?
