I should have clarified, it isn't exactly profitable for most developer/builders to do for-sale condos that are high-rise concrete construction, margins are very tight and achievable $psf is generally too low to move forward with, which is why you will really only see wood-frame, low-rise condos move forward (not to mention they are smaller, faster and relatively de-risked in comparison).
All of the high-rise or low-rise concrete buildings you are seeing are purpose-built rental buildings, no for-sale projects have been happening for a while and likely won't until $psf for condos rise and available inventory drops. This article touches on that:

In my experience, concrete high-rise construction generally requires above $600-650psf minimum to be profitable (which was the break even point when high-rise construction began to take off in Surrey City Centre). Even Calgary's best positioned newer condos are only achieving $500-550psf and I don't anticipate they will rise to a profitable level which is exactly why the Anthem, Bosa, Qualex-Landmark, Fram-Slokker, Batistella, Great Gulf, Torode and others with land use on high-rise residential buildings that are intended to be condos haven't been moving forward and in some cases have seen the developers list the lots for sale. You might see a handful happen but they are riskier than what most financiers will accept at this time.
People can wish and wish for these to happen, but no one is touching those projects until those thresholds are met as financing doesn't work, so no it isn't really viable. Not to mention high-rise buildings at subprime TOD locations, those are straight up doomed for condos.
