Benjamin Couillard is a PhD candidate at the University of Toronto whose research looks at things like residential choice and housing supply. And in this recently published paper, he studies the causal effects of rising housing costs on fertility. Here's what he found when examining US Census Bureau data:
...rising [housing] costs since 1990 are responsible for 11% fewer children, 51% of the total fertility rate decline between the 2000s and 2010s, and 7 percentage points fewer young families in the 2010s. Policy counterfactuals indicate that a supply shift for large units generates 2.3 times more births than an equal-cost shift for small units. This analysis concludes that the supply of housing suitable for families can meaningfully contribute to demographic sustainability.
Intuitively, it makes sense that rational adults might consider where they would put a child if they had one, or had one more, and consider the cost of this incremental space. Housing is expensive in major urban centers. Perhaps it's no surprise that Canada, which is known for its broadly unaffordable housing, has fallen into the "ultra-low fertility" category.
But I think this fertility-housing relationship is an important one to call out when considering appropriate public policies. Housing is often viewed through the lens of what bad things will happen if we build it. That's why we do shadow studies, force stepbacks, charge development charges (impact fees), and the list goes on.
What is harder to grasp is what happens when we don't build new housing. Most — or at least many — seem to agree that not building enough housing hurts overall affordability. But what this study also demonstrates is that not building enough family-sized housing is bad for making babies!
This has all sorts of socio-economic repercussions, one of which is that a country now has to rely more heavily on immigration in order to offset a shrinking population base. It becomes a larger economic problem. When framed this way, it makes me wonder: why do we tax new family-sized homes the way we do?
An alternative approach to encourage more infill family housing might be to eliminate development charges, building permit fees, parkland fees, and as many other government fees as possible on all three-bedroom or larger homes. And the reason you would do this is because the economic and demographic cost of not building is even greater.
Based on the work of Couillard, we know at least one of the outcomes: more babies.

I love mid-rise buildings. I think they are an incredibly livable scale of housing, which is why I am looking forward to moving into Junction House
The University of Toronto is looking for a Director, Real Estate to manage their tri-campus portfolio of income producing real estate, as well as the development opportunities that they have on and adjacent to their three campuses. The downtown campus alone is over 120 buildings across 130 acres.
A good friend of mine is helping with this search; I went to the University of Toronto (twice); and I believe that institutions, such as U of T, play an important city building function. So I’m sharing this opportunity with all of you today. For more on the University’s development strategy, click here.
They are looking for someone with 10+ years of experience. The salary will be competitive and commensurate with this level of experience. And you would be reporting directly to the Chief of University Planning, Design & Construction.
If you’re interested, you can apply here. You have until January 25, 2019 to do that. I hope the position gets filled with a star. Also, sorry if this post isn’t relevant to you. Regularly scheduled programming will resume tomorrow.
Here are two excerpts from a recent Globe and Mail article -- titled "Toronto's mix of planning rules limits growth of mid-rise housing" -- that speaks to this dynamic:
For well over two decades, Toronto’s official plan has called for transit-oriented intensification along the “Avenues,” much of it expected in the form of mid-rise apartments that can be approved “as of right” – meaning without zoning or official plan appeals. Such buildings are often seen as more livable and human scale than 50- or 60-storey towers.
Yet, ironically, the highly prescriptive Mid-Rise Guidelines – combined with skyrocketing land, labour and building costs, as well as timelines that can run to six years for a mid-sized building – have turned these projects into pyramid-shaped unicorns, often filled with deep, dark and narrow units dubbed “bowling alleys.”
“The economics are so frail,” says architect Dermot Sweeny, founding principal of Sweeny & Co., who describes the angular plane requirements as “a massive cost” because they make the structure more complicated and expensive while reducing the amount of leasable or saleable floor space.
The critiques extend beyond the industry. Professor of architecture Richard Sommer, former dean of the John H. Daniels Faculty of Landscape, Architecture and Design at the University of Toronto, describes the controls in the guidelines as “very crude.” “They’re built around a mindset of deference to low-rise communities.”
My opinion is that, at a minimum, we need to revisit the "guidelines" that govern these kinds of projects and we need to make this scale of development "as-of-right." In the same way that laneway suites work, where you simply apply for a building permit, we need to make it just as easy for mid-rise housing. There just too many barriers and too many opportunities for something to come up that could hold up the entire project for months or years.
Building at a variety of scales is important for the fabric and vitality of our cities. Unfortunately, I have all but made up my mind that small doesn't work unless it's as-of-right. I would love to build another laneway house and I fully expect that to happen at some point in the near future. But I just can't seem to get my head around another mid-rise building right now. I wish that wasn't the case. And it's certainly not because of a lack of effort.
