Getting legal help

Asking for a reconsideration can be difficult. Try to get legal help. If you can't afford a lawyer, a community legal clinic might be able to help.

How to ask

You must ask for a reconsideration in writing, within 90 days of getting the decision from Service Canada. There's no form to use.

You must write a letter and include the following information:

  • your name, address, phone number, and (SIN)
  • why you disagree with the decision and want a reconsideration
  • any new or extra information that Service Canada does not have that could change their decision

Make sure to sign and date your letter. Then send it to the address on the decision letter that you got from Service Canada.

Making a late request

If you miss the 90-day deadline to ask for a reconsideration, you can still ask. But you also need to ask for an extension of time.

Explain why you could not make your request within the 90 days. And include any information that supports your reasons for being late. Then Service Canada will decide whether or not to accept your late request.

Getting a decision

Service Canada reviews your request for a reconsideration and looks over your application again.

Then, they send you a decision about the reconsideration in the mail. This can take several months.

If Service Canada changes its original decision, your application will go ahead. For example, this means you could:

  • start getting OAS
  • start getting the amount you thought you should get
  • start getting a different amount that Service Canada thinks you should get, for example, an amount lower than you were getting

If Service Canada keeps its original decision and you don't agree with that decision and their reasons for making it, you can appeal to the (SST). See Step 3.
