Which of the following is a component of the Old Age Security (OAS) in Canada?

The Guaranteed Income Supplement (GIS) is indeed a critical component of the Old Age Security (OAS) program in Canada. The OAS program provides a basic level of income to seniors aged 65 and older, and the GIS specifically aims to offer additional financial support to low-income seniors. It is designed to supplement the OAS pension, ensuring that individuals with limited financial means receive a higher overall benefit.

This focus on providing a safety net for vulnerable segments of the senior population aligns with the program's objectives of reducing poverty among older Canadians. The GIS is income-tested, which means that eligibility and the amount received are determined based on an individual's income level. This is a crucial feature that distinguishes it from other types of benefits typically aimed at broader populations.

In contrast, the other options do not pertain to the OAS framework. Disability pensions are related to employment insurance and support individuals who are unable to work due to disability. Employment insurance benefits assist those who are temporarily unemployed or unable to work but are not specifically designed for seniors. Family allowances involve financial support for families with children, which is distinct from the objectives of the OAS program. Thus, the Guaranteed Income Supplement is uniquely aligned with the broader goals of the OAS initiative.
