The post office in Marystown is back up and running today after a persistent odour in the building forced a series of temporary closures over the last few months.
Canada Post says employees have been instructed to close the post office whenever they smell the odour.
The building was closed again this week on Wednesday and Thursday due to the issue.
An ongoing investigation into the source of the odour is underway, including testing.
Despite the implementation of a number of fixes, the source of the smell remains a mystery.
Canada Post says it continues to work on a solution to the problem.
