Old Age Security - After you've applied

6. After you’ve applied

Service Canada will inform you by mail whether your application was approved or not, or whether additional information or documentation is required to make a decision on your application.

See While receiving an Old Age Security Pension for information on such things as benefit payment dates and rates, income tax and when to notify Service Canada.

If you are dissatisfied with the decision of Service Canada concerning your application for an OAS pension or benefit, you may request reconsideration of your case. You must make your request for reconsideration in writing within 90 days after you are notified in writing of the decision.

Reconsideration is a new review of your application by the Department. Service Canada staff who were not involved in making the original decision will review your application, as well as any new information supplied by you, or by others on your behalf.

How to request reconsideration of an Old Age Security decision

You must make your request for reconsideration in writing within 90 days after you are notified in writing of the decision.

Prepare your written request for reconsideration and include:

  • your name, address, telephone number and Social Insurance Number;
  • a detailed explanation of why you want reconsideration; and
  • any new information that could affect the decision.

Sign and date your written request and submit it by mail to the return address on the decision letter.

Reconsideration can take several months to complete, depending on the case. Service Canada will re-examine your application and will send you a letter that explains its decision once the review is completed.

If you disagree with the reconsideration decision

If you disagree with the reconsideration decision, the next step is to contact the Social Security Tribunal to appeal.
