What this data can and can’t tell you
- Protection. A National Historic Site designation recognises significance; it doesn’t by itself protect a building the federal government doesn’t own. Legal protection comes from provincial and municipal designations, whose own registers aren’t open data outside Québec.
- Provincial and municipal lists. The local and provincial lists outside Québec aren’t published openly, so this page counts what Wikidata records and pages only the places an encyclopedia describes.
- The grade. History isn’t one of Canada’s graded pillars, so this page describes and compares without a letter.
- 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.
- The tiers. National Historic Sites and the most protected buildings form the top tier; recognized federal buildings, stations and lighthouses the second; provincial and municipal listings the third.
- 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.
