They've also been purchasing (expropriating) several properties over the last several months -- a 7-11 has been boarded up and ready for demolition. Reportedly roughly $100M have been 'committed' (contracts that locks up future payments, expropriation, studies, design, survey/early works, etc).
Also, the city designed many areas as 6-storey transit oriented corridor with allowances for up to 30-stories closer to downtown parts.
Shovels should finally hit the ground next year if this survives election. Municipal politics will probably be very dirty on the LRT topic as it has been in the past.
