Four open sources feed it (OpenStreetMap, Wikidata, ODCAF and the federal and Québec heritage registers), merged so each place appears once. Forts, houses, lighthouses and churches stay only with a sign they are open to visitors, and businesses such as hotels, restaurants and tour operators are left out. Every place is tied to the town by its 2021 outline, or by lying within 5 km of it.
Places to visit: Canada publishes no open tourism list, so this one is assembled from OpenStreetMap (© OpenStreetMap contributors, ODbL), Wikidata (CC0), Statistics Canada’s ODCAF museums and galleries (2020, Open Government Licence – Canada), the federal and Québec heritage registers and CPCAD’s national parks, and it reflects what mappers and editors have recorded. Forts, houses, lighthouses and churches count only with a sign that visitors are welcome. Places sit in each town’s 2021 census outline; visitor counts are Wikidata’s latest, with their year.
