Definitely an idea whose time has come. The gravy train is over for single occupancy vehicles coming into Toronto/downtown core from the Markham/Mississauga 905.
Put that money back into road and transit infrastructure. Best use and example of a user fee, IMO.
Are you assuming this is a one way toll? because guess what, Torontonian's are not going to be happy when they realize they too will have to pay to drive out of the city
That's a good question that is entertained all the time when they vote themselves a raise.
