Remember when people in Etobicoke got together to protest Mississsauga buses and block them from operating on Burnhamthorpe? And these peopel had the support of the City of Toronto, which banned Mississauga buses from the Islington terminal. Eventually, Mississauga Transit was forced to reroute the 86 Burnhamthorpe Express (later the 206, now the 76) from Burmhamthorpe and inconvenience many riders. The ridership of Burnhamthorpe corridor has continuous declined since then.
And let's not also forget the fact the City of Toronto bans 905 transit from operating within its borders. Toronto isn't a good neighbour, isn't it? Toronto as a whole is the worst NIMBY of all.
