This report outlines concerns in relation to the exclusion from participation in the Canada Pension Plan (“CPP”) of individuals who are appointed to certain boards and tribunals by Order-in-Council (“OIC”) on a part-time, or per diem, basis. The Regulation preventing part-time and per diem OICs from making CPP contributions will mean that unless there is other pensionable income, the part-time and per diem employee will lose entitlement to CPP disability benefits. The appendices A and B to this report assess the impact on two current per diem employees.
