A legal strike by OPSEU Local 441 members is now affecting services at Lanark Leeds and Grenville Addictions and Mental Health.
The agency says unionized workers walked off the job at 12:01 a.m. Monday after the two sides failed to reach a renewed collective agreement.
LLGAMH says it offered employees wage increases above inflation during negotiations. The agency says the union rejected all offers and began strike action.
During the strike, LLGAMH says it will continue to provide high-priority services for its most vulnerable clients. Non-critical services have been paused for the time being.
The agency says it does not have a legislated essential services designation. However, its leadership team has identified services that must continue to protect the health, safety and well-being of clients.
Supports will continue for clients from group homes, treatment homes and the HART Hub. Some psychiatry and psychotherapy supports will also remain available.
Paused services include general case management, general psychotherapy, the drop-in centre, the social recreation program, the vocational program, the family support program, the housing program and administrative support.
LLGAMH says affected clients have been contacted. The agency says it is also working with community partners to reduce the impact on people who rely on its services.
Clients with urgent concerns have been given information about the agency’s triage line.
Anyone experiencing a crisis is asked to call the national crisis line at 9-8-8 or emergency services at 9-1-1.
The agency says the strike will not affect construction of the HART Hub at the Leeds Grenville site. That project is still expected to open in the summer of 2026.
