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.
Later boundary forms
- In a later year, this CSD contained St. Ignace, 1881 (92.5% of this CSD's polygon).
