I think it's not just the Liberals, but the Conservatives that are at fault. Neither parties have done much of anything when they were in power to help this and other significant stagnation issues over the least two or three decades.

At least for Toronto, the federal and provincial governments had to be punched in the sides to make public transit investments after being forgotten for most of a half century, and even then the new constructions are still quite inadequate and will require at least two more decades of consistent work before things reach a decent level, presuming that other areas don't get worse in the meantime.

It's unfair to just blame the Liberals. All our leading parties suck because they see themselves as invulnerable. They've gotten used to being an oligarchy, and the NPD is no longer scaring them, but instead have become a part of the oligarchy. Layton was great, Mulcair was okay, but Singh is just a puppy following Trudeau. Without someone new (it can be the Rhinoceros Party for all I care) getting a decent number of seats to become a legitimate threat to the oligarchy and make them actually move their asses for real and positive change, I think we're stuck with nothing but corrupt personal interests.
