Dear Doug, great and useful contributions, thank you very much. My case is this: worked in Romania for ten years between 1990 and 2000, lived and worked in Canada for six years (all taxes paid), from 2001 to 2006, then moved to Romania to be my aging parents, where I have since my residency and work. Question 1: Given that the international social security agreement with Romania will come into force on 01.11.2011, does it apply retroactively if the aforementioned six Canadian years are taken into account (and into account)? This is intended for totalization in both countries, I would decide to apply at the age of 65. Maybe it`s Romania. Question 2: What Canadian pension benefits would I be entitled to if I added up the three contribution segments? You can also qualify for a partial agreement of the OAS. The OAS is approximately $15.00 per month for each year of stay in Canada after the age of 18 and before receiving the OAS. Maintaining the OAS has no influence on U.S. social benefits. I am not an expert on the Canada-Philippines agreement, but here is a link that you might find useful: I see that you are an expert in the field and that you enjoy reading your answers to other people`s questions. My wife and I have been Canadian citizens since the mid-1990s, but we have lived in the United States since the late 1990s. While I was earning in the United States and amassing 40 Social Security credits, my wife earned a salary in the United States and lived in Canada for about 4 years. Could his stay of more than 18 years in the United States be used to help him meet the 10-year Canadian residency requirement or the 20-year A-Canada residence requirement for OAS benefits for 20 years? Is the OAS`s power about $578 per person or couple? Is there a chance or risk that the OAS may be reduced/eliminated in the future, especially for Canadian citizens who are entitled to rights in another country such as the United States? I live in Canada all the time and emigrated with my family from Trinidad in 2003, where I lived for 49 years.

I participated for 24 years in the social security program in Trinidad, including the three years between 2003 and 2006, when I was living in Canada, but I was employed in a Trinidadian company.
