Before you file a tax return with the CRA using the information delivered by Auto-fill my return you have to ensure that all proper fields on the return are filled in correctly, including information not delivered by Auto-fill my return, and that the information provided is true and accurate. It remains the taxpayer's responsibility to report their income before a tax return is submitted to the CRA.
If you are missing or notice a mistake on an information slip, contact the employer, payer, or administrator for that slip.
