On September 8, 1949, Toronto held a groundbreaking ceremony at the intersection of Yonge & Wellington to celebrate the start of construction for its very first subway line. (Formerly known as the Yonge line, now called line 1.)

The scene looked like this:

Some of the buildings in these pictures still remain, but many do not. The first picture is looking north. And the second one is looking south toward the lake. You can see the rail corridor in the background.

There’s something very urban about these images. The storefronts look active and the streets are full, though no one appears to be live tweeting the event and this clearly pre-dates Toronto’s transformation into the most diverse city in the world.

But my favorite bit of these photos is the people hanging out on the exit stair, watching the march toward modernity. It’s an image that no longer correlates to Toronto.

Starting in the late 1930s, New York City began hiring photographers to document each and every building in the city. It did this to improve the accuracy of its tax assessments, and so every photo was taken with a sign board indicating the building’s block and lot number. The photos looked like this (taken from here):

The initiative produced over 700,000 black and white photos, all of which have been recently digitized according to the New York Times. The Times also recently published this interactive piece where they go back to these archival photos to see how the city has and hasn’t changed. 

In the late 1930s and early 1940s, documenting a city and its buildings was clearly a manual endeavor. Today we have Google Street View (launched in 2007), which has now photographed much of the world. Many countries, including all of North America, are reported as having “mostly full coverage.”

But already autonomous vehicles (and their supporting services) are starting to scan and map our cities in new ways. So it will be interesting to see what ends up getting built on top of this data. I am certain it will empower much more than just better tax assessments.

Happy New Year, friends. Thanks for reading over the last year.
