Which of the following is considered a provincial government public plan?

Workers' compensation is indeed considered a provincial government public plan. It is designed to provide financial and medical benefits to employees who are injured on the job or become ill due to work-related circumstances. Each province in Canada administers its own workers' compensation board, creating programs tailored to the needs of workers and industries within that province.

The other options do not qualify as provincial government public plans. Employment Insurance (EI) is a federal program offering benefits to individuals who lose their jobs through no fault of their own, while the Canada Pension Plan (CPP) is also a federal program that provides retirement and disability benefits. The Guaranteed Income Supplement (GIS) is an additional source of income for low-income seniors, which is administered at the federal level. Thus, recognizing the specific role of workers' compensation as a provincial plan allows for a clearer understanding of how various government programs function within Canadian social services.
