I hate circular logic.
You want the bigger home because you have created multiple dependants that require it. But you can't afford the bigger home, even after all the tax breaks and freebies society provides to those with dependants.
Toronto developers build tons of small condos because they are cheap. Comparatively speaking, Toronto is pretty cheap when it comes to downtown living. Supply and demand doesn't care about size...if this latent demand is there for large family condos as you claim...they would build them. That's why they generally change the building configuration to more smaller units after initial sales offices open. Forget what Jennifer Keesmat says....she's in over her head.
The solution for families who can't afford to purchase real estate large enough for their needs used to be to simply rent. But 25 years of rent control has screwed that option quite nicely.
Talk about circular logic. Your solution is for families to rent. Great. Where shall we rent when there are almost no 3br units on the market? Our only choice is to live in small condo units or move to far suburbs and commute. Or if one is lucky you can find a great walk up in a stable neighbourhood. That is a rare gem indeed.
Supply and demand market is tightly controlled and regulated by governments. Developers don't give a crap. Most built cheap and fast. The city and suburban regulations are why we don't have large units. Minimum parking requirements and forced amenity spaces that are barely used. This is why developers build condos with fancy and expensive amenities that are barely used most of the time - to meet dumb city regulations, driving up capital and maintenance costs.
This is what I mean by lack of choice. You either have to buy or rent a fancy but small condo with 24/7 security a pool, etc or a live in a house in Newmarket/Barrie/Burlington/Oshawa.
The main reason developers don't built them is because it's cheaper and more profitable to build high rise or low rise. This is fully controlled by regulation. The city and province can change the rules but don't as they are paid for by developers and they need to perpetuate the Canadian cultural dream of a big house and a big yard. That's the only place we are supposed to raise kids. There are not supposed to be kids in the dirty city so why bother to build family apartments in the city.
Canada generally has two extremes: high rise or mid-rise: both are costly and inefficient. The most efficient city form is mid-rise. This is why European cities are much more efficient. Their built form is made for people not cars. There are few high rise buildings and almost no single detached homes. They are walkable and easy to serve by transit or cycling infrastructure. They have a much better place making. The exact opposite of what we have here.
Jennifer Keesmat is a breath of fresh air in this city. She is not over her head at all. She is doing quite well . Especially given the shit show that is City Hall with the old dinosaur councillors that squash good ideas and force stupid ones down the civil service. The missing middle development options is really what the city needs. It's more gentle density, its cheaper to construct but needs applications to be processed faster so the project get approved. Reason it takes so long is they are under staffed for a booming city with so many development applications. Again, this is controlled by city spending priority. No such thing as a free market.
Here is are some ideas: What if the city charged a property tax based on the cost to service the property? What if suburbs didn't subsidize low density and charged the full capital and operational costs to build roads/schools/highways/transit/police/parks, etc? What if the city actually funded the planning department by doubling its size and giving it clout to make decisions on changes and requirements to zoning, transportation, transit and outer city infrastructure .
