I'm starting to think maybe the current lack of integration isn't so bad. For example,iIt does keep the Rexdale people out of Mississauga, which is obviously a good thing.
That's who fare integration would mostly benefit: Toronto's outer neighbourhoods full of criminals like Rexdale, Jane-Finch, Malvern... if the City of Toronto doesn't care about these people to reduce their isolation and give them more different opportunities, then I don't see why the 905 should care either. Fare integration is 100% a Toronto problem, as far as I'm concerned.
Rest of the 905 is already integrated with each other and with GO. And while TTC doesn't provide any service outside of Toronto's borders, the 905 systems and GO already provide a lot of service within Toronto. So from a 905 perspective, fare integration with TTC is not necessary and no one should not be pushing for it especially if the TTC is not.
If there is fare integration, it's the TTC who should be paying for it 100%, not the 905. The 905 should not pay a single penny to Toronto. The 905 systems already stretch their budgets to provide connections into Toronto, and not only does the City fo Toronto not reciprocate, it bans the 905 systems from picking up passengers within its borders. As a result of Toronto's hostility, cost recovery ratios of the 905 systems are below 50% while TTC is 70%. So it's obvious that if there is a cost to fare integration that the TTC should bear that cost 100%.
