Ugh. It's wasted breath to have a conversation on such matters when people post, "we need to build cities to live in" inferring its 905ers clogging the roads or mentioning a subway under the street which is of little use to anyone living, building a business, dying in South Riverdale or Parkdale.
Once again, it takes me over an hour to go 8 kilometres by transit doing bus/subway/subway or streetcar. That is much longer than even ten years ago. That is not how to build a city. The Ontario Line should have been completed 10 years ago. It's far too late opening ten years from now
You should advocate for better transit then, not more traffic lanes. The best cities in the world are the ones that make the streets more friendly and accessible to pedestrians, not the ones that prioritize speed and convenience for drivers.
Love Park is a great example of how removing a highway off-ramp created a beautiful and enjoyable public space for most Torontonians. CafeTO and Cabbagetown Parkscape are other examples of how transforming traffic lanes into outdoor dining and greenery improved the public realm for locals, while only upsetting those who didn't live in the area and oonly see these places as a place to drive through not live in. These projects all came at the expense of car infrastructure, but imagine how much more livable and safer Toronto could be if we did this city-wide on every street with more than one lane.
