I don't care if I sound rude: what a bunch of whataboutery nonsense.
curves: go read the document I linked to
here. Read it carefully. The gist is this was previously private land that was transferred to the City's possession 40 years ago, with the caveat that they weren't allowed to do anything else with it. The owner of the Glenmore Landing mall was obliged to maintain it. Now said owner wants to do something with it, and the City wants housing built, so they're going to sell it back to the owner to build apartments. For how much? Probably the appraised value, which you can go look up on

There's no grand conspiracy here to enrich private enterprise by the selling of public lands on the cheap. This land in question is a couple patches of grass between the mall, 14th Street and 90th Ave: it's totally useless—and worthless—to anyone else but RioCan.
