Can an employer put caps on benefits for absent workers?

Our broker has recommended, as a cost-saving measure, a time-limit cap on benefits when someone is absent from work, something that will impact workers on long-term disability. Is this legal?

Question:

I have a question concerning company policies with respect to benefit caps. Our broker has recommended, as a cost-saving measure, a time-limit cap on benefits when someone is absent from work. So, for example, if an employee is absent for more than one year they would be removed from the health and dental portion of the benefit plan as a corporate policy. Even though not explicitly stated, this would most impact someone on long-term disability who may have expensive drug claim needs. Could this expose us to a lawsuit in terms of human rights and perceived discrimination based on disability?
