What this data can and can’t tell you
- Provincial and municipal lists. Only Wikidata gives open access to listings on provincial and municipal registers outside Québec; without an article such a place is counted but not paged.
- The federal register. The federal list is complete and open: Parks Canada’s directory for the designations, the Canadian Register of Historic Places for what each one is and why it matters.
- Map points. Pins for federal places come from Wikidata rather than Parks Canada, which gives no points.
- The grade. History is described, not graded, for every Canadian town.
- Protection. Being on these registers doesn’t mean a building can’t change. Federal designation commemorates; protection is provincial or municipal, and those lists aren’t open here.
- People and events. National historic persons carry no place in the open file. They appear on a town’s page when born there (same name, same birth and death years) or when a historic place inside it carries their name and its record names them with their dates; national historic events don’t appear.
- The tiers. Three tiers: the top for National Historic Sites, classified federal buildings and Québec’s classements, a second for the other federal designations, a third for provincial and municipal listings.
