The City of Toronto recently started an initiative called “Comprehensive to the Core.” It’s a look at how downtown Toronto–which is growing at 4 times the rate of the rest of the city–should continue to grow moving forward so that it remains a great place to live, work, learn and play.

Here’s a presentation that was delivered last month by the city. It’s mostly infographics and so it’s a quick and fun read. And here’s an infographic that does a nice job of summarizing what’s happening in the core of Toronto.

What it’s saying is that downtown Toronto–which they consider to be bound by Bathurst Street in the west, the Don Valley Parkway in the east, the lake in the south, and Dupont Street in the north–is responsible for 51% of the city’s entire GDP. It’s also responsible for 33% of all jobs in the city and 25% of the city’s entire tax base. And yet in terms of size, it represents only 3% of the city’s land area.

That’s a powerful reminder of the economic potential of density and agglomeration economies. It’s also a reminder that we shouldn’t let politics deprive our economic engine of the services and investments it needs.
