Editing Old Age Security (section)

==Enrolment and eligibility ==
Prior to 2013, a person needed to apply to Employment and Social Development Canada (ESDC)<ref name="auto">{{Cite web|date=2015-10-29|title=Old Age Security: Your application |url=https://www.canada.ca/en/services/benefits/publicpensions/cpp/old-age-security/apply.html |access-date=2021-08-28 |website=www.canada.ca}}</ref> and meet the eligibility criteria to receive benefits. Since 2013, the enrolment process has become increasingly automatic as Service Canada are now permitted to use data from Income Tax files.<ref>{{Cite web|date=2018-01-09|title=Backgrounder: Old Age Security (OAS) automatic enrolment|url=https://www.canada.ca/en/employment-social-development/news/2018/01/backgrounder_oldagesecurityoasautomaticenrolment.html|access-date=2021-08-28|website=www.canada.ca}}</ref> For persons who are not enrolled automatically, a manual application process remains in place.<ref name="auto"/>

Eligibility for Old Age Security is straightforward for most Canadians. Persons who have lived outside of Canada can refer to official documentation for details including residency requirements and a list of reciprocal agreements with other countries which may allow pooling of residency periods to increase eligibility for Canadian or foreign pension rights.<ref>{{Cite web|date=2012-07-25|title=Canada's international social security agreements|url=https://www.canada.ca/en/revenue-agency/services/tax/canada-pension-plan-cpp-employment-insurance-ei-rulings/cpp-ei-explained/canada-pension-plan-employment-insurance-explained-13.html|access-date=2021-08-28|website=www.canada.ca}}</ref>

Low-income OAS recipients may apply for an additional amount in the form of the Guaranteed Income Supplement (GIS). A domestic partner's income affects the income threshold and payout.<ref name="gis">{{Cite web |date=2023-04-19 |title=Guaranteed Income Supplement |url=https://www.canada.ca/en/services/benefits/publicpensions/cpp/old-age-security/guaranteed-income-supplement.html |access-date=2023-04-27 |website=www.canada.ca}}</ref>

To receive the full OAS pension, a person must have lived in Canada for at least 40 years after turning 18. If less than 40 years after age 18, the amount of partial OAS pension received is prorated, based on the number of years they have lived in Canada divided by 40. For example, a person living in Canada for 34 years after age 18 is eligible for a partial 85% OAS pension (34/40=0.85).<ref>{{Cite web |last=Canada |first=Employment and Social Development |date=2015-10-30 |title=Old Age Security: How much you could receive |url=https://www.canada.ca/en/services/benefits/publicpensions/cpp/old-age-security/benefit-amount.html#h2.5 |access-date=2024-09-01 |website=www.canada.ca}}</ref>
