Although there are several types of reviews, the process itself is simple and fast in comparison to an audit.

The review process starts when the taxpayer receives a letter from the CRA explaining that they want to verify the accuracy of certain information, such as the amounts entered, says Gosselin. “Even if tax filing was done perfectly,” adds Ball, “there will still be spot checks to make sure the deduction or credit actually exists. In some cases, the CRA just wants a copy of the receipts, like donations.”
