Change of Address

As Sarah’s representative with the Canada Revenue Agency, I can do some useful stuff to file her income taxes but one thing I cannot do is change her address.  I asked Sarah to change her address with CRA by phoning them.  I wasn’t sure if she had done it yet.  So I phoned CRA to check her account but they told me they couldn’t tell me if she had changed her address.  Then I asked them something else about her account and I had to verify her address to get the information. I said 36 Bourne Street and they said I was wrong.  So I knew that she had changed her address.  Ha I fooled them.
