The Geospatial Centre has made available historical maps of Waterloo Region from 1815 to 1923. KMZ (map files) can be downloaded and viewed within Google Earth.

Digital historical street network for Waterloo County

In 2011, the staff in the University Map Library re-constructed the 1955 street network for Waterloo County. In 2017, the staff at the Geospatial Centre updated the project with 2016 data, allowing scholars, historians and community residents to study and analyze past and present street patterns. 

To visualize the changes which have occurred within the Waterloo Region multiple web maps were created to showcase the urban growth, road network, and road name changes between 1955 and 2016.
