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. 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.
- 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.
- Québec’s register. Québec’s Répertoire du patrimoine culturel records the province’s classements and declarations and every municipal citation, each with a description and a point.
- 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.
- 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.
