CANADA'S social security system for the aged is like Britain's - two-tiered - consisting of the Old-Age Security (OAS) scheme and the Canada Pension Plan (CPP.) The full OAS pension is C$385.81 (HK$2,160.53) per month.
OAS applies at 65 and is not means tested, although the Government claws some money back from the wealthy by taxing it.
There are minimum residence requirements.
The Government funds the scheme on a pay-as-you-go basis out of general revenue.
Because of its heavy exposure to the scheme, the Government has made efforts to use the tax system to avoid excessive payments to the wealthy.
It had long been a tradition in Canada that everyone should receive the same pension. But this ended in 1989 when claw back provisions were introduced on incomes above C$50,000.
Last year, those earning in excess of C$84,000 had all their OAS pension taxed.
