In the complementary system to the Canada Pension Plan, or in the parallel plan in Quebec under the Régime des rentes du Québec, the perverse effects need to be avoided, meaning penalizing individuals who set aside savings for their retirement. When someone contributes to a TFSA—or CELI in French—it doesn't count as pension income, guaranteed minimum income. There is nothing stopping us from saying that, up to a certain amount, income from the supplementary Canada or Quebec Pension Plan is subject to the same treatment. We can use that innovation and avoid penalizing those who made the decision to save for their retirement.
