Post office is no longer in this building, https://www.cbc.ca/news/canada/north/atlin-bc-postmaster-resigns-1.6684360 indicates that this had moved to the "Sincerely Yours" general store building and (when that  burned to the ground in Sep 2022)  moved to a former morgue. The postmaster has resigned effective 23 Dec 2022; as this was contracted to a local business (CPC pays C$500/month) location of new PO (if they find one) is TBD.
