Not remotely true. Further, based on polls, if we had made this a singular issue, the highway would have been defeated.
A poll by Ekos conducted in December 2021 found that almost half of respondents (49 per cent) are opposed to Highway 413.environmentaldefence.ca
Even if that poll was true, it does not change the fact that the governing majority party that was re-elected supports the 413. Also- it's just for GTA residents. Remember that the election was provincial, not regional.
With the support of 17% of all eligible voters in Ontario. 83% either voted for parties opposed to the highway or didn't vote.
I'm not a fan of Douggie or the PCs either, but you can't put the people who didn't vote into the group that voted for parties other than PCs. That's not fair and you don't know their intent on this subject.
