Sounds to me like "don't blame the drug pushers for the blight of addiction - they're just responding to the greed of their kingpin! Blame the end users instead."
There are many developers in Toronto who are meeting the demands of investors who employ better architects and turn out better projects than Canderel does. Canderel clearly has no appreciation for architecture, design or urbanism AT ALL - which is problematic considering the scale and height of the projects they've been responsible for building in the heart of our city.
And as for more density, more people, more retail, & so forth... there is more to good city-building than cramming in as many people as possible into a monoculture of glass and steel tombstones (& offering the people a few more concourses and food-court options as some sort of exciting side benefit). You can visit at any fourth-rate insta-city in China if you want to see what that kind of urbanism looks like. (Spoiler alert: It's oppressively ugly and soul-crushing).
