Daily insights for city builders. Published since 2013 by Toronto-based real estate developer Brandon Donnelly.

This is a chart from a recent blog post by Ryerson University's Centre for Urban Research and Land Development. It shows net intraprovincial migration across the regions of the Greater Toronto Area. And what you are seeing here is people moving from expensive and built-up areas like the City of Toronto and the Region of Peel to lower cost areas further outside of the city.
This is interesting for a couple of reasons. One, it's very much a natural market outcome. Many people tend to "vote with their feet" and look for greater housing affordability. And two, this is a trend that existed prior to COVID-19. It is not the death of cities. In the words of Ryerson's CUR, it's about people looking for more affordable lower-density housing.
But to what extent is "lower density" the key deciding factor? In other words, how much of this is consumer preference and how much of this is people being forced out by a lack of infill housing supply?
It’s that time of year again. It’s time to make predictions for the upcoming year and time to look back on the ones we all got wrong from a year prior. I don’t recall many people (if any) predicting that a pandemic would cripple the global economy.
I like how Scott Galloway put it in his 2021 predictions post. It’s obviously better to be right than wrong, but it’s okay to be wrong. The value in writing down your thoughts is that it forces you to think. It’s the reasoning that matters. (It’s one of the reasons why some people write blogs.)
A key theme in Galloway’s predictions post is something that he calls “The Great Dispersion.” This involves two things: (1) The physical distribution of products and services over wider areas and (2) the bypassing of gatekeepers and other intermediaries (which is something the internet has always been good at).
You could interpret this as being directly antithetical to cities. Urbanism, after all, is all about agglomerations. But I think it’s more nuanced that that. Cities have generally always had both centralizing and decentralizing forces. The two can co-exist.
I will get into this in more detail in my own 2021 predictions post. But in the mean time, I would encourage you check out what Scott Galloway recently published, over here. And if any of you have any thoughts about what’s in store for us in 2021, please leave a comment below.
Don’t worry, it’s okay if you’re not right.


Since 2012, a team at New York University has been working on something called the Atlas of Urban Expansion. What they are doing is collecting and analyzing data related to the quantity and quality of urban growth around the world. Everything from population densities to how well the streets were laid out during each geographic expansion.
The Atlas defines a city as having at least 100,000 people, which is a commonly used benchmark. According to this definition, there were 4,245 cities on the planet as of 2010. Included in their study is a representative sample of 200 of them, all of which can be found here.
They are also, rightly, looking at each city in terms of its extrema tectorum -- the limits of its built-up area. This is as opposed to using administrative boundaries, which wouldn't be as relevant in a study like this.
I really like the animations that they created depicting urban growth from 1800 to 2014, because they show: (1) where each city started (the dark nucleus); (2) how different urban shapes emerge as a result of geography, transport, and other factors; and (3) how land consumptive many of our cities have become in recent years.
