Service des presatations 3 Bureau des ententes de securite sociale Régie des rentes du Québec 1055 René-Lévesque Boulevard East, 13th Floor Montreal, Quebec H2L 4S5 Thank you for dispelled the confusion on all this. In any event, I will wait a few more years before applying for benefits under either of the two programs. In the meantime, I will depend on the returns on my investments and U.S. Social Security to fund my part-time work. Hello Eric – I don`t know the age rules you can/should apply for for your US Social Security, but I do know that everything you do about your US SS does not affect your CPP or YOUR AEO. Therefore, you can apply for your CPP as early as age 60 (at a reduced rate), but the earliest time you can apply for the OAS is the age of 65. If a person is not entitled to a benefit on the basis of the periods applicable under the legislation of the States Parties, which are added together under Article 12, that person`s entitlement to that benefit shall be determined by adding those periods and eligible periods completed under the legislation of a third country to which both States Parties are bound by social security instruments: which provide for the addition of periods. Data protection law requires us to inform you that we have the right to collect this information in accordance with section 233 of the Social Security Act. Although it is not mandatory for you to provide the information to the social security authority on the provision of the information, a certificate of coverage can only be issued if an application has been received. .
