Cross-year identity established by spatial polygon overlap (SAME_AS chains across the Canadian Census Subdivision boundary files).
Boundary continuity (non-identical overlaps)
Spatial polygon overlaps with adjacent census years where the boundary shifted enough that the SAME_AS chain didn't merge them. These show where the territory came from and went to even when it isn't tracked as the same persistent place.

Census tabulations from the 1871 Census of Canada, transcribed and georeferenced by the Canadian Peoples / TCP project, hosted at the HGIS Lab, University of Saskatchewan. Persistent place identity computed from spatial-overlap chains across all available census years (1851–1921). Identity grounding to Wikidata performed via the HGIS Canada Knowledge Graph project's MCP-assisted disambiguation pipeline. See the About / Methodology page for the full data pipeline.
