Possibly but this is about reducing congestion on the 400 series highways and making people want to use public transit. If you live in Toronto chances are you already use the TTC to commute and if you don't your commute likely isn't that long.
So would that include people that use the 401 as a trucking lane therefore increasing the price of goods?
And if Toronto can do it why can't every community that has a 400 series highway running through it charge a congestion toll?
Burlington, Milton, Mississauga, Oakville, Pickering, Ajax, Oshawa, Whitby, Hamilton, Kitchener.
I believe Mississauga and Brampton have as many, if not more, highways running through them as Toronto does.
You'd have to pass tolls up to 5 times for a one-hour drive.
