In the online survey of a representative national sample of 1,002 Canadian adults, 36 per cent of respondents said Trudeau has been the best prime minister, since 1968, followed by Stephen Harper with 19 per cent of the votes, Jean Chretien with 12 per cent, and Brian Mulroney with 6 per cent.
Mulroney, marred by the Schreiber inquiry, has lost more than half of his supporters since 2007 with most of the gains going to Stephen Harper.
Angus Reid also asked Canadians about who they thought the worst prime minister was.
Both Harper and Mulroney, were honoured with that distinction, each earning 19 per cent of the vote, respectively.
And to no one's surprise, the anti-Liberal bastion of Alberta was the only province in Canada to choose Trudeau as Canada's worst prime minister.
