The data, released by research firm Leger, is based on an online survey of 1,528 Canadian adults over the weekend using computer-assisted web-based interview technology.
He can not be given a margin of error because internet-based polls are not considered random samples.
The poll asked respondents which of the six candidates in the election they believe would be the party’s best leader, who will unveil his new leader on September 10th.
Leger executive vice president Christian Bourque says one of the issues they face when polling Canadians about a race for party leadership is that about a third seem indifferent.
Evidence shows that 58 percent of respondents said they did not know or did not choose any of the above when asked which candidate would be the best Conservative leader.
As for Conservative voters, the poll shows that 23 percent of respondents said they did not know and only 8 percent did not choose any of the above.
Of the Tory voters who responded to the poll, 44 percent believe that Pierre Poilievre, the longtime Ottawa MP known for his attacks on the government and the Bank of Canada for inflation, would be the best party leader.
Charest, Quebec’s former prime minister, came in second with 14 percent of the Conservative vote, according to the poll, while the other four remaining candidates were ranked much lower.
Examining supporters of other political parties, Leger polls show that 25 percent of federal Liberals and NDP voters believe Charest would be the Conservative leader.
He also suggests that 11 percent of both the Liberals and the NDP would vote for Brown, who is mayor of Brampton, OD, and has previously led Ontario Progressive Conservatives.
On the contrary, the data show that only 6% of liberals and NDP supporters believe that Poilievre would be the best choice.
The findings come as one of the main tasks facing Conservative leadership candidates, if they win, will be to increase support for the party in the run-up to the next federal election, especially in wealthy Ontario.
“The only way they can win Ontario again and do better in Quebec is to really keep voters away from the Liberal Party and away from the NDP,” Bourque said.
Leger figures also show that 57 percent of those who support Canada’s most right-wing People’s Party believe that Poilievre should be the next Conservative leader.
