The pain to remove the bike lane in many sections, with hardened infrastructure like the reconstructed sections of Bloor (Bathurst-Avenue) and University as well as the efforts to remove the bike lanes in some parts will likely make it challenging, time-consuming and a pain to remove. It's easy to see that the government is set on removing it, but take one look at the road in some sections and it's easy to see that the benefit obtained from removal is not worth the pain of removal.
Also you gotta remember, it was also possible that it was just a way to get more suburban votes. Now that he's been comfortably re-elected, he might not see this as a big priority anymore, especially that the local MPP in Etobicoke-Lakeshore was not re-elected. This is just not a fight worth fighting for anymore, especially with the courts and stuff. He's won what he needed to.
I do unfortunately see the Bloor ones in Etobicoke getting removed, especially with their quick-build implementation and design but there's still hope that they will come back in the future while still complying with Bill 212 or after the PCs are gone.
