Hi Blue Clip, I would really appreciate if you can join the discussion on the forum. My least favourite part of OSM is when users work against each other in their mapping efforts and I am concerned this could be happening here because of a disagreement/misunderstanding in how these post offices should be mapped.

Separately, can you comment on your data source? If you are using the Canada Post website, as trigpoint linked, this could mean your contributions need to be deleted. OpenStreetMap is quite strict about data sources to avoid issues with its open data licence.

Thanks,
