CERB was delivered by both Service Canada and the Canada Revenue Agency. We worked very closely together to use the best information available to us.
We know, of course, that CERB was based on an attestation basis. That was a very deliberate choice that was made at the outset to ensure that we were able to get benefits out to people as quickly as possible. Effectively, that meant that many of the typical integrity measures we take at the outset, when we decide whether someone is eligible for employment insurance, were not done. In fact, we were relying on people to tell us if they were eligible, with the expectation that integrity measures would take place at the back end.
We certainly use techniques, including a large number of...and other measures, to identify situations where people were clearly defrauding the system. However, it's expected that in the vast majority of cases where individuals will be found not to have been eligible, it will be due to honest mistakes.
Looking at the numbers, as we know, letters have already gone out in some cases in situations where we can't tell whether someone was eligible or not and we're looking for additional information. As my colleague has already explained, more will be known when the 2020 tax information comes in.
