Canadian Human Rights Benefit Regulations

9 The provisions of any benefit plan respecting leave of absence that result in differentiation being made between employees in the rates of contribution of an employer or employees, or both, to the plan, if such differentiation consists of a reduction in the contributions required of an employee who is absent on a maternity leave of absence or on a leave of absence due to sickness, injury or disability and an increase in the contributions of the employer to the plan by reason of that reduction, do not constitute the basis of a complaint under Part III of the Act that an employer is engaging or has engaged in a discriminatory practice.
