The Canada Pension Plan (CPP) enhancement, which was introduced on January 1, 2019, is designed to help increase retirement income for working Canadians and their families.The CPP is a mandatory pension plan financed by contributions from employees, employers and self-employed individuals. It covers virtually all workers in Canada except Quebec, which administers its own plan called the Quebec Pension Plan (QPP). The CPP replaces a basic level of earnings for contributors upon retirement, disability, or death.
