It always has. I can (or could) take Yonge all the way up to Barrie.
The problem being that priority has been given to the least efficient, most costly and most destructive method of transport for 60+ years.
Maybe those who choose to drive alone in their own vehicle don’t need to also be given the high speed red carpet treatment.
That's very nice, but to undo that status quo, we actually have to do something about it.
Look, I hate the overreliance we have on cars as much as you. The propaganda that our urban planners bought into in the wake of World War II has done irreparable damage to the fabric of our society. But there is no point in crying about spilled milk - this is the situation we have. We have introduced a drug into society and made it widespread, and before we can wean its users off of it, we need alternative options. It is not enough to make some symbolic moves at reducing car dependency like adding in some bike lanes and increasing service on a few GO lines and pretending we are good to tear down a major highway. You want to talk about the Gardiner making the city unlivable, how livable will it be when all of the cars that have been displaced from that highway now end up clogging our already congested streets?
There are currently two throughways on the shores of Lake Ontario that go from the same place to the same place, and along a route that will soon have all-day, every 15 minute commuter trains.
Great, and what about the rest of southern Ontario? Look at the situation in Milton, for example. I might be able to have some sympathy for your point if there was all way, 15 minute service on the Milton line, but we are decades out from that being remotely a possibility. Right now, on weekdays your choices are to either take the 22 that runs every 2 hours down to Oakville to transfer to the Lakeshore West line, or to use the 21, which runs every hour after the morning rush hour, and is going to get caught in traffic on the Gardiner. On weekends, the 22 doesn't run, so your options are either to take an agonizingly slow bus that gets stuck in traffic, or to stay home. And you wonder why someone might choose to take their car? If memory serves, I had no say in my parents choosing to move us out to Milton when I was 11 years old, so I'm not sure why I should be punished for the decision my parents made 15 years ago and have to double my trip time when I can be downtown by car in less than an hour. My time is not so worthless that I can afford to waste 2 hours every time I need to get downtown. And remember, that travel time presumes I catch the vehicle on time. Heaven forbid I miss it, and have a 1-2 hour wait for the next one.
Travellers from Richmond Hill, Aurora, Kitchener, Hamilton all have similar disparities in travel time by car vs. transit. These are not trivial disparities, 5 minutes or so, these are a full 30-60 minutes.
Getting rid of the Gardiner is a very lofty plan, but it's a plan for a different city than Toronto, like London. No one on this board will live to see transit implemented in their natural lifespans that will be sufficient for the Gardiner to be torn down. Not one.
