Federal Pensions include government programs such as Old Age Security (OAS), Guaranteed Income Supplement (GIS) and Spouse’s Allowance. Often, to be eligible, you must first file a personal income tax return and then apply for the income or benefits. The amount you receive may depend on your level of income. Most people who work in Canada pay money into the Canada Pension Plan (CPP). In Quebec, there is a similar pension plan called the Quebec Pension Plan (QPP).
