That's a good question. I don't know. What the CRA has ended up doing is they've done six individual tax gaps, and even they have shown that between $20 billion and $24 billion is missing that they're failing to collect.
I can understand why they don't want to do an overall tax gap, but given the record of misleading information of the CRA—and I have a long list of examples of those—it's best if an outside group does it. In this case, the PBO is the group to do one. I think this is the third PBO who has been trying to get the information.
