SEIU Healthcare is a Canadian trade union representing more than 60,000 workers in Ontario, Canada. Through collective bargaining, the union represents workers in hospitals, home care, nursing and retirement homes, and community services. The union has been active in Ontario for over 70 years. SEIU Healthcare is distinct from SEIU Local 2 Canada, albeit both SEIU Healthcare and Local 2 are affiliated with SEIU. The majority of SEIU Healthcare's units do not have the right to strike, as they are bound by Ontario's Hospital Labour Disputes Arbitration Act (HLDAA).
