For Radio-Canada, Roberto Rocha has created a terrific map showing the age of buildings in Montreal.

Nice. Anyone know how to view the map full-screen?
If you’re on chrome, try this: right click on the map and select ‘inspect’. Several windows should open, one showing the html, where something is selected. Scroll up in the html view to ‘div id=”map” class=”map”‘, and select that. Make sure the shown web-page is still wide enough to map and text side-by-side. Then in the “styles” window, change “width: 50%” to “width: 100%”, and close the inspector (‘x’ in the corner).
Very cool map. They have my house being constructed in 1882 but the deed says 1891 though.
What fun. I notice that my building on des Soeurs-Grises is blue, indicating 1990-2015. The building was actully constructed around 1940(?), so they’re clearly using the year it was converted to condos, even though the structure and façade are intact.
The construction year field is probably from a database file on open data montreal. I know the file, and it’s not 100% accurate (data entry errors, I presume).
The big church in my neighbourhood is tagged as 1963, an obvious mistake. Alexis Hamel gives it 1931, much more plausible. On the other hand, the map is on the nose that the building I live in dates from 1927, which agrees with the info on my insurance policy.
ant6n: thanks for the answer to the map question.
This is a fun way to show trends, but like @Robert J pointed out it’s full of errors.
I looked up my house and instead of my building, there’s a non-existent address. The date on one of my neighbour’s buildings is off by a decade.
I think the problem is with the city’s own data set. Whenever a building undergoes a conversion, it’s construction date is listed as the date of conversion. I used to live next to an office building on Parc Av that was converted into condos in 2003, and its date of construction is listed as 2003 in the city’s property roll.
Was excited to see a red dot not too far from my house, a building built in 1600! (6217 Christophe-Colomb). Turns out it’s off by over 3 centuries. It’s inconsistent in regards to conversion as well. Sometimes they change to the new reno’s date even when it’s minor. However, some on my street still have the date of the original building even when it was completely torn down and replaced (2 of those are 1950s bungalows that replaced 2 stories buildings, nothing is left from the original construction). It’s fun to compare neighborhoods though. I expected Lachine to have more red and orange.
You may be able to find more accurate info in the Lovell guides, that’s how I found my place (although it took some detective work because of the change in street numbers at some point)
Thanks, ant6n, but I contacted the author and he provided me this link:
