I wish Canada post was this efficient. The staff held my parcels that were stranded because of border restrictions due to Covid. Staff are professional and dedicated.


Very helpful, attentive and gracious postal employees here in Oroville, WA. They should all receive our thanks and praise for their hard work in these difficult times.
