FCR executive said it had to do with the way city subsidies work. Perhaps, but consider that the 175 subsidized units would be the same configuration (mostly studios and one-bedrooms) as the market-rate units. And it's a lot less risky to rent smaller market-rate units than larger ones.

Likely those who value the location--the proximity to transit and nightlife. That suggests singles and couples, not families.
