The base layers we're including are boundaries, cities/towns, roads, water features, and buildings (Carleton and Ottawa only), which are what you'd generally want in a nice basemap. The datasets are organized by geography and those available only to Carleton community members are indicated by a Carleton logo.
Our Make a basemap for anywhere in Canada (including Ottawa-Gatineau) help guide may be useful.

Ontario
If you're looking for a specific city or region, check if it has an open data site and, if so, search there first.
You can also find more information on our Make a Basemap guide.
Finally, there are provincial- and territorial-level datasets in the Natural Resources Canada products listed in the Canada section, below.

- Municipal Boundaries for free via the Ontario Data Catalogue (use the Lower Tier shapefile to dissolve as there are null values and gaps in the Upper Tier shapefile)
- Ontario townships: Geographic Township Improved for free via Ontario GeoHub
- Counties: there does not appear to be one freely available dataset of just Ontario counties. However, you can download either of these datasets and then dissolve (QGIS | ArcGIS Pro) based on the 'upper tier' property:
