"CRA Result Code: 31
The information sent to the Canada Revenue Agency doesn't match the information currently on record, which was provided by Service Canada.
If you are unable to resolve the issue after verifying your identification, for you to receive all the benefits and deductions to which you are entitled and to verify our validations, the Canada Revenue Agency needs you to file a paper return and attach all pertinent slips and receipts. The Canada Revenue Agency regrets the inconvenience. "
