People pay into CPP when they work, and the program provides payments to workers and their families.
OAS and CPP combine with company pensions and retirement investments to provide Canadians with one of the best retirement investments in the world. Along with the Old Age Security pension, OAS also includes the Guaranteed Income Supplement. The latter provides extra money to low-income pensioners. To be eligible to receive this supplement, you must also be receiving the Old Age Security pension. OAS also has the Spouse's Allowance and the Widowed Spouse's Allowance.
