The Saskatchewan government has officially announced a move to privatize cleaning services in government buildings.

The move is expected to save $3.5 million annually.

The province has already identified 12 cleaning suppliers that will be moving forward in a selection process. All 12 companies are Saskatchewan based.

“This is an excellent opportunity for the Saskatchewan business community. The successful firms moving on range from well-established companies to smaller, employee-operated businesses,” Minister of Central Services Christine Tell said in a written release. “Additionally, all firms have offered to hire current cleaning employees.”

Government cleaning staff was notified about the change on March 13. The Ministry of Central Services will work with the employees and their unions as per the collective bargaining agreement.

Private cleaning staff is expected to start work on July 1, 2017 in 95 government buildings.
