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.

ON115005— year-scoped identifier from the Canadian Census Subdivision boundary file - Persistent place ID:
PLACE_ON111013— computed from spatial-overlap chains across census years - Wikidata: not yet grounded. This page covers a place whose persistent identity has not yet been linked to a Wikidata entity. Identification is via TCP UID and spatial polygon only.
Sources
Census tabulations from the 1881 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.
