Demand for mental-health and addiction support is high and rising. Graduates work as mental-health and addiction workers, recovery and outreach staff and community mental-health workers in agencies, treatment programs and health services.

Delivered with hands-on labs and placements at Loyalist College's Belleville campus in eastern Ontario. This program is on Loyalist's official PGWP-aligned programs list (CIP 51.1501), so graduates may qualify for a Post-Graduation Work Permit — the final decision always rests with IRCC.
