Three quarters of Ontarians disapprove of the job Liberal Premier Kathleen Wynne is doing, a new Forum Research poll suggests.

Broad public support for Wynne has been dreadful for some time, and the Liberals continue to flounder even in their Toronto stronghold, said Dr. Lorne Bozinoff, president of Forum Research.

“Of primary concern for the premier should be her declining support in Toronto, as she now sits third behind both the Tories and the NDP,” Bozinoff said in a release. “Without the same massive support in Toronto she received in 2014, her re-election prospects look dim, at best.”

Just two in 10 (18%) approve of the job Wynne is doing and 73% disapprove.

Meanwhile, the poll shows Progressive Conservative Leader Patrick Brown would be the next premier if an election were held today.

Forty per cent of the electorate say they would support the PCs, the survey found, with the NDP and Liberals basically tied with 27% and 25% support respectively.

Middle-class males from ages 45 to 64 earning $40,000 to $60,000 formed the largest group of PC supporters.

Liberal supporters are mostly under the age of 34, have a post-graduate degree, and live in Toronto or eastern Ontario.

Those supporting the NDP came from Toronto and northeastern Ontario and are between 35 to 44.

Of the three main leaders, the NDP’s Andrea Horwath was the most popular with an approval rating of 35%.

Brown has an approval rating from a quarter of voters, but has a disapproval rating of 34%, and four in 10 said they didn’t know.

“While Patrick Brown’s PCs see a slight dip in support in August, for the most part his support remains steady, despite perceived controversies (during nomination processes),” Bozinoff said.

The phone survey of 981 random Ontarians was conducted on Aug. 23 and 24, with a margin of error of plus or minus 3%, 19 times out of 20.
