Coverage, sources & uncertainty
This preview preserves 159 draft events, 128 source records and 13 selected movement records. It is a cumulative research base, not a complete history. Each event links to its evidence and research limitations.
Nation-authored Indigenous histories, municipal histories, modern treaties, migration and many social histories need further research. Incorporation dates do not date human occupation. Empty peoples fields do not imply an absence of Indigenous peoples.
Native Land reference territory geometry is not distributed here while commercial licensing is unresolved. Pre-1867 political geometry and exact movement routes are unavailable. French translations are incomplete; missing translations are not generated or presented as reviewed.
Source collection: October 11–12, 2026. This is not a live feed. Corrections require a reviewed catalogue update; original source identifiers and version hashes are retained. Map images are rendered references, not archival photographs.
