This is a telling map from Jens von Bergmann. It shows the changes in population density across Toronto from 1971 to 2021 (measured in people per hectare). What is obvious is the spikiness of our city. We have been very effective at adding lots of people downtown, along the central waterfront, and in certain other pockets. But at the same time, we have let our older inner city neighborhoods move in the opposite direction and lose people.

The irony of this outcome is that we have long created policies that refer to these areas as being "stable" neighborhoods. The idea was that they weren't supposed to change, at least not too much. But what this data shows is the opposite. By restricting growth, we actually created the right conditions for them to lose people as demographics changed and household sizes got smaller, among other things. We created unstable neighborhoods.

Thankfully, we have started to change course and allow some intensification. We're not there yet, but I do believe that the next 50-year map will look quite different than the one you see here.
