While I'm glad that this program identified some of the symptoms of rampant deficiencies in the condo market in Ontario and Toronto, I have grave concerns with some of the avenues of reasoning this documentary follows.
Despite the core complaints of deliveries of deficient product and insufficient liability, this program keep trying to lead us down garden paths like the argument that city planners should more aggressively centrally plan "family-oriented communities". The complaints are completely unrelated concept from community design. Moreover, increases in central planning of that kind are likely to only exacerbate the market distortions already present.
Even more worrying, it goes on to suggest that investment or speculation in real estate as investment properties (for foreigners and otherwise) as a primary cause. While it does seem likely that distortions elsewhere in the financial system might be having undesirable unintended consequences in the real estate sector (such as excessive investment), I doubt that that it's the root issue. In principle, we should be glad for foreigners bringing their capital to Canada and investing it in our housing sector.
I'd suggest looking more closely at the The Condominium Act of Ontario as a causative factor. It mandates a single business architecture for condominiums, one that at this point I think many would argue is seriously flawed. Complex businesses (organisations) like condominiums need business process innovation and variation, and it is arguably as important as technical innovation. Markets tend towards more equitable arrangements in the absence of encumbrances, even with externalities, and when they aren't and a lot of people are going home upset, something odd is going on. A one size-fits-all model, no matter how well-meaning the designers, cannot suit everyone all of the time.
