How to read these numbers
What this data can and can’t tell you
- The grade. History isn’t one of Canada’s graded pillars, so this page describes and compares without a letter.
- 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.
- The federal register. Parks Canada’s Directory of Federal Heritage Designations lists every National Historic Site, federal heritage building, heritage railway station and lighthouse; the Canadian Register of Historic Places adds their statements in English and French.
- 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. The open directory puts its national historic persons nowhere, so a town shows one only on firm ground: a birth there, matched by name and life years, or a historic place there named for the person whose record says so. Events are left out.
- Provincial and municipal lists. Provincial and municipal listings here come from Wikidata alone, since the provinces’ own registers can’t be reused; a listing needs an encyclopedia article to get a page.
- Map points. Parks Canada publishes no coordinates, so federal places are pinned where Wikidata puts them.
