OAS entitlement and deferral rules for immigrants to Canada – MoneySense

You generally need 40 years of residency in Canada after the age of 18 to qualify for the maximum OAS pension. The maximum monthly payment as of the fourth quarter of 2023 is $707.68 for someone who started their OAS at age 65. Someone aged 75 or older would be entitled to up to $778.45.

Exceptions to the OAS residency requirement

There may be situations where you qualify for the full pension without meeting the 40-year residency requirement. One example would be if you were over 25 and lived in Canada or had an immigration visa on or before July 1, 1977.

Another instance where you may qualify for a higher pension is if you lived in a country with a social security agreement with Canada. Time spent in other countries may count towards your OAS residency formula. If you worked outside Canada for the Canadian Armed Forces or an international charitable organization, this time might also count.

Deferring OAS to increase residency requirements

If you have under 40 years of residency, your pension is pro-rated. You need to have lived in Canada for at least 10 years after the age of 18 if you apply for OAS as a Canadian resident. If you live outside of Canada when you apply, you need 20 years of residency.

Interestingly, Amin, you can defer your OAS pension after age 65 to increase your residency requirements. This can work well for someone who is trying to get to 10 or 20 years, respectively, to qualify for the pension at all. In your case, the deferral will not have an impact on the residency calculation. I will explain why.

The reason is an OAS recipient deferring their pension after age 65 can only benefit from one of two enhancements: one, the years of residency; or two, the age-based increase. If you defer OAS to after age 65, your age 65 entitlement increases by 0.6% per month or 7.2% per year of deferral. You can start it as late as 70 for a maximum 36% increase.

If you get an extra year or 1/40^th of residency, that amounts to a 2.5% boost in your OAS.

Unfortunately, Amin, you cannot get the 2.5% residency boost and the 7.2% age boost for deferring. You get the higher of the two, which is obviously the age-based adjustment of 7.2%.
