IMO this is junk reporting.
There is no student housing project underway anywhere near Concordia.
The only residential project underway near NorQuest is The Parks, which isn't really "student" housing necessarily in the same way that Horizon Residences or The Laurent are student housing.
Similarly, it's the same for MacEwan, where Station Lands (and I suppose The Parks also) is really only the nearby multi-fam under construction, and again it's not really student housing. Sync111 could maybe count, but it's been past substantial completion for a whole year now.
That, or the author has some real loose definitions of "underway", "student housing" and "near"
