If we toll the roads downtown, we need to toll the roads in the suburbs as well. Especially the 401, it should have tolls all the way from Milton to Oshawa, and other highways as well. Traffic in the suburbs in many places is often worse than downtown.
Also moving jobs to the suburbs is NOT a good idea. Toronto has done this a lot by moving jobs to Mississauga, Markham, etc. It does not work. The result is that (a) people often commute long distances between suburbs because they cannot find a job locally and (b) most jobs are poorly served by transit and located in "business parks" surrounded by acres of parking. This only serves to make traffic congestion worse. The best thing to do is to concentrate office jobs in a few locations well served by transit (like downtown, North York Centre, Mississauga Centre), build good transit connections between the various centres, and ban the construction of business parks in areas with poor or no transit service (like the State Farm business park at Aurora Rd/Highway 404 in Aurora, and the Loblaws business park at 407/Mississauga Rd in Brampton).
