The Amalgamation of Toronto

This map is based on the City of Toronto’s Annexation Map. The City of Toronto Archives have a high quality digital version of it here.

Wikipedia has a detailed timeline of Toronto’s amalgamation and annexations between 1791 and today.

This map was made possible because of Mapbox, Turf, and QGIS.

Correction (Nov. 6, 2018): The map previously mislabelled Forest Hill as being annexed in 1924 – it was actually annexed in 1967. Thanks to

Robin McLeod for identifying the error and letting us know.
