Old Age Security
The Old Age Security (OAS) pension is a monthly payment you can get if you are 65 and older. In some cases, Service Canada will be able to automatically enroll you for the OAS pension. In other cases, you will have to apply for the Old Age Security pension. Service Canada will inform you if you have been automatically enrolled.
In most cases, you do not have to apply to get this benefit.
Why you may have to apply
You may have to apply for the Old Age Security. We may not have enough information to enroll you automatically.
