The Cineplex Entertainment poll asks people to pick the country's best possible leader from a list of Canuck actors including Patrick Huard, Ryan Reynolds, Catherine O'Hara, Ryan Gosling and Rachel McAdams.
Thirty-one per cent of respondents chose the 82-year-old Plummer, while 22 per cent voted for William Shatner.
Jim Carrey rounds out the top three, with 14 per cent of supporters.
The online poll, conducted by Ipsos Reid between Feb. 16 and 21, is part of a series of promotional film facts meant to celebrate "100 Years of Movie Memories."
The complete survey asked 4,009 adults several movie-related questions, including which movie best represents Canadians' ideal summer.
Cineplex says the quiz boasts an estimated margin of error of plus or minus 1.5 percentage points, 19 times out of 20. Survey takers were disqualified if they said they hadn't watched at least one movie a month.
