What program requires pensioners to reside in Canada for a specific period of time?

Old Age Security (OAS) requires Canadian residency for eligibility. A pensioner must typically have resided in Canada for at least 10 years after age 18 to qualify.

CPP (C) is contributory and based on employment earnings, not residency.

RPP (B) is an employer-sponsored pension, not linked to residency.

GIS (D) is a supplement to OAS and also requires residency but is dependent on OAS eligibility.
