The high cost of implementing tolls will minimize any benefits from the road tolls.  Meanwhile, areas near the DVP and the Gardiner will be even more congested with people by-passing the road tolls.  This will make surface transit even slower and less reliable than it is now.  Nice.  

Build more transit and make it reliable before adding road tolls.  The TTC is already at capacity.  Suggesting that people change their commute times is stupid.  Rush hour already goes from 7:30 to 10 and 2:30 to 7:30.  The DVP is as busy northbound in the mornings as it is southbound.   So when are commuters supposed to travel - 6 am and 2 pm?  I would rather pay the $60 vehicle registration tax again than have the tolls implemented.
