The Ontario Public Service Employees Union is growing in Grey Bruce.
The union has moved into a new, larger office in Owen Sound at the BDO Dunwoody building near the Bayshore Community Centre.
Officials say they needed a larger space to meet the needs of its new and existing members in the region.
There is also an area for activities and training.
OPSEU will use the office to serve about three thousand members in Bruce, Grey, Dufferin and North Wellington Counties.
They are employed at all local hospitals and include other health care, municipal and public service workers.
