The Old Age Security program is the largest statutory program of the Government of Canada, and consists of the Old Age Security pension, the Guaranteed Income Supplement, and the Allowance. The Guaranteed Income Supplement is provided to low-income seniors aged 65 years and over who receive the Old Age Security pension and are below a low-income cut-off level.

This evaluation examines take-up of the Guaranteed Income Supplement by various socioeconomic groups, the characteristics of those who are eligible for the Supplement but do not receive it, and barriers faced by vulnerable groups.
