Since 1981, the Executive Council of Manitoba has included a Minister responsible for the Workers Compensation Act. The specific ministerial designation has changed several times. The current position is not a full cabinet portfolio, and has always been held by a minister with other cabinet responsibilities.
Most ministers responsible for the Workers Compensation Act have also been Ministers of Labour. The current minister is Nancy Allan, who is also the Minister of Labour and Immigration.
Assessments under the act are levied upon employers and gathered into a common fund out of which benefits are paid to workers who are injured as a result of their employment. Administration and adjudication are carried out by the Workers Compensation Board of Manitoba.
