The federal directory kept by Parks Canada supplies most of these places; provincial and municipal lists outside Québec aren’t open data, so only the ones Wikidata documents with an article appear.

Points from Wikidata (Parks Canada’s files carry none) and from Québec’s register, as mapped there. One place, placed by its register’s municipality, has no point and isn’t on the map.

How to read these numbers

What this data can and can’t tell you

  • The tiers. Tiers follow the designation: national recognition and classement first, other federal designations next, provincial and local listings last.
  • 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.
  • The grade. There is no history grade: the page sets out the record and compares it with other towns.
  • People and events. Parks Canada’s open file gives its national historic persons no place. A town’s page names one only when the person was born there (matched by name and both life years) or one of its own historic places carries the name and its record speaks of them; national historic events stay off.
  • Provincial and municipal lists. Outside Québec, provinces’ and municipalities’ heritage registers aren’t open data; their places are known only through Wikidata items with a register number, and only those with an encyclopedia article get a page.
  • The federal register. Every federal designation is in Parks Canada’s directory, and the Canadian Register of Historic Places gives most of them a bilingual statement of significance.
  • Map points. Federal places get their map points from Wikidata, since Parks Canada’s files carry none; they are as mapped there.
