Canada's Public Pension system has two components:
In addition there is a special benefit called "The Allowance" which is an income supplement. The Allowance is paid to 60 to 64 year-old spouses or common-law partners of pensioners who receive GIS. There is also an Allowance for the Survivor for widows and widowers aged 60 to 64 who have low income.
In 2005 2006, 4.2 million OAS and Allowance beneficiaries received $29 billion in benefits.
Canada Pension Plan is described in a different section of this site. It is often considered another part of the public pension system. However, it is funded through employee and employer contributions, not taxes. The federal government is responsible for investing the money and administers it.
