The Canada Pension Plan is a contributory, earnings-related social insurance program. It forms one of the two major components of Canada's public retirement income system, the other component being Old Age Security (OAS). Other parts of Canada's retirement system are private pensions, either employer-sponsored or from tax-deferred individual savings (known in Canada as a Registered Retirement Savings Plan). As of September 2017, the CPP Investment Board manages over C$328.2 billion in investment assets for the Canada Pension Plan on behalf of 20 million Canadians. CPPIB is one of the world's biggest pension funds.
