Remember to orthogonalise buildings. The shortcut in iD editor is Q, and in JOSM is S.

Hi, remember to use Q to orthogonalize buildings. Use shortcut Q in iD, or S in JOSM.

The Great Trail part of Fundy Footpath is not a cycle route so I've changed the relation to route:hiking with this changeset #92361447. Please revert if wrong. osm.org/changeset/92361447

I didn't realize that tag existed. The POI is now changed. Thanks for the advice!
