The Ministry of Labor is now looking over the Canada Post Office in Dryden.
The building remains closed after staff refused to enter this morning over health concerns.
Asbestos and mold were found and removed in the building on the weekend.
A Union Rep say their concerns have been addressed and they are anxious to return to work.
The Ministry will have the final say on whether the building is safe for staff.
The office remains closed and no mail is coming in or going out.
