My hope is that Toronto has an army of transit advocates both in the profession (who eventually will replace the dying old heads) and not, who care deeply about this and spend most of their advocacy on it and a few other things (since we don’t have to fight for survival like in the states).
The opposition NDP (who don’t like P3s) and liberals (who first proposed all this) also have a chance to use this as a club to beat Ford in the 2029ish election while concern about Metrolinx management and high costs relative to European/asian comparators is coming up among laypeople on both sides.
