Here is an updated map of frequent service bus routes in the outer suburbs of Toronto during rush hour periods.

Red = a bus route which has service every 10 minutes or less.
Blue = a bus route which has service every 15 minutes or less.
Mississauga may be missing a route or two, as I have to go through all their routings yet, as they have the most confusing route structure.
But overall it shows who the leader is, and that is Brampton.
Oakville did not make the cut, as their rush hour service is every 20 minutes.
