How to read these numbers
What this data can and can’t tell you
- Map points. Parks Canada publishes no coordinates, so federal places are pinned where Wikidata puts them.
- 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. Tiers follow the designation: national recognition and classement first, other federal designations next, provincial and local listings last.
- 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.
- 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.
- Protection. Federal recognition isn’t a planning control: buildings the federal government owns follow its heritage policy, while others are protected only by a provincial or municipal designation.
- The grade. There is no history grade: the page sets out the record and compares it with other towns.
