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.
- People and events. Persons of national historic significance come with no location; a town gets one only by birthplace (name and both life years agreeing) or by one of its own places that bears the name and whose record tells the story. Events, which can’t be tied, are left out.
- Protection. Québec’s classements and citations carry legal protection: work on a classified building needs the minister’s authorization, on a cited one the municipality’s. Federal designations commemorate.
- Québec’s register. Québec is the one province whose register is open: classements, declarations and municipal citations, described by the ministry in French.
- The federal register. Federal places come from Parks Canada’s directory, which counts National Historic Sites, federal heritage buildings, stations and lighthouses; their statements are the register’s own.
- 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.
