After seeing this beautiful 6-storey and 21-unit social housing project in Lyon, I decided to retweet it and share the fact that we recently had a site under contract in Toronto with the intention of doing a very similar build. We wouldn't have been able to do the same outdoor spaces at the corner, but it was going to be 6 storeys and without any setbacks. The overall dimensions appear to be similar.
However, in the end, we had to drop the site because the margins were simply too thin. I was disappointed. Of course, some people responded to my quote retweet by calling this an example of developer greed. But once again, I don't think most people understand how development economics work. If the margins are too thin it, among other things, means:
It's going to be hard/impossible to raise capital and finance the project
You might be better off buying a "risk-free" government bond instead
That unexpected situations could sink the project (i.e. you lose money)
To give a specific example, let's assume that your expected base case rent at the time of occupancy is $4.75 psf. This would mean that if your average suite size is around 600 sf (which ours was), you would need a face rent of about $2,850 per month.
But what happens if you're off by only $0.25 and your face rent for this same 600 sf apartment is now $2,700 per month at initial lease up? $150 per month may not seem like a big deal, but it is. If you capitalize this income at something like a 4% rate, you will find that it becomes material.
This is what I mean by "the margins are too thin." And it's similar to any other professional not wanting to take on a job because they might lose money or because it's "not worth their time." It's about managing risk and understanding the opportunity cost of taking on such a project.

I have vivid memories of being in a broker meeting many years ago talking about development land in Vancouver. Our team's comment was that it felt expensive. I mean, Toronto was expensive, and Vancouver was even more. Why? It has one-third the GDP of Toronto. The response we got was something like this: "Yeah, Vancouver may seem pricy, but you just need to get into the market. Then in 5 years you'll be happy you did."
Well it's been more than 5 years and now this is the market:
The market for development sites is being tested by a roughly 50-per-cent drop in value since 2022, according to Mark Goodman. The principal of Goodman Commercial Inc. said Broadway Plan sites, for example, were selling for about $200 per square foot buildable three years ago. Sellers can now expect closer to $100 per square foot buildable, he told BIV. Goodman currently has three Broadway Plan listings.
Of course, Toronto is in a similar situation today. If there's no market for new condominiums and apartment rents aren't growing, then high-density land values are going to feel the impact. But I do think it's interesting that, in some ways, our response was being anchored by our experience in Toronto. What we know, and have accepted, often becomes a baseline for assessing if something else feels expensive or cheap.
I sometimes see the same thing with long-time developers. They remember what they used to sell and/or rent apartments for, and have a harder time accepting today. But this is a positive thing if it compels greater deal scrutiny. Advice like "you just need to get into the market" is never sound. But if you were to take this approach, I would bet that today is a better time than 5 years ago.

Here's an interesting table via the Globe and Mail:

As of January of this year, residential real estate loans in Canada totalled approximately $2.07 trillion. On top of this there's another $350 billion in home equity lines of credit. This brings total loans secured by residential real estate in this country to about $2.42 trillion.
What this chart really shows, though, is how concentrated the mortgage market is. The "big six" banks make up about 74% of the market. If you include Desjardins, the total increases to 80%. That's pretty much the market.
