The federal government has indicated that it will expand WITB by approximately $250 million per year beginning in 2019 to “provide additional benefits that roughly offset incremental Canada Pension Plan (CPP) contributions for eligible low-income workers.”1 The changes to CPP will be phased in, starting in 2019. These changes mean that workers will be paying higher CPP contributions from their paycheques. Low-income workers especially could feel the impact on their take-home pay. This backgrounder provides an introduction to the program, explores how it impacts low-income workers, and how it could be improved.
