Along the 403 Corridor to Hamilton (extending the 15 even more?), along the 401 Corridor to KW (a new branch of 25?) or even along Highway 4 and 7 to KW via Stratford.
Today, as I was driving back from Mississauga to Waterloo, around Milton I saw crazy amount of EB traffic. Then it just occurred to me how people from Western <UWO> (the majority of which, I thought, would be from GTA, but what do I know...) are supposed to go home, if Grey Hound is expensive and carpool rare.
Also, why not connect all the universities/colleges (McMaster, Guelph, UW <including Stratford campus>, Laurier, Conestoga, UWO) together?
Ps: I made sure to look through all pages to avoid making a duplicate thread, and there was nothing about Go Transit to London here.
