Well, a few reasons. In the 2022 election Ontario had a voter turnout of 44%, meaning whoever gets chosen, it's not by "most people" because most people didn't even show up. Of those who did, 40% of votes were cast for Ford's party. So in terms of popular vote and raw numbers, about 18% of valid electors actually checked a box next to a Conservative candidate. Doesn't that feel kinda weird?
From the 40% of votes that were cast for a Conservative candidate, they received 68% of the seats. So even among the Ontarians that voted, 54% of them voted for someone left of Conservative and instead we got 68% Conservative representatives in parliament.
Of the places that voted for Conservative, most of them had relatively low population. Unsurprisingly, if you look at a map of Ontario for the riding results by colour, you can basically see where all the population centres are because they are the ones that aren't blue. So, as a concrete example, the places he's removing bike lanes are predominantly not places he was votes for.
To conclude, basically we don't vote for him. But he wins anyway due to structural bullshit, a lack of proportional representation, and then a bunch of apathy likely brought on by a lack of representation.
