OAS Benefits

If you meet the Canadian residence requirements, you may be eligible for income-tested benefits under the OAS program as early as age 60.

  • Guaranteed Income Supplement: If you live in Canada and you have a low income, this monthly non-taxable benefit may be added to your OAS pension.
  • Allowance: If you are 60 to 64 years of age and your spouse or common-law partner is receiving the OAS pension and is eligible for the Guaranteed Income Supplement, you may be eligible to receive this benefit.
  • Survivor’s Allowance: If you are 60 to 64 years of age and you are widowed, you may be eligible to receive this benefit.
