Chair, I can give you a flavour of why there are technological challenges. The GIS determination was made after we received individuals' tax returns for 2020. That was done, we'll say, in June 2021. Individuals had started receiving their benefits. Entitlements had been determined.
Now, as far as a solution goes, if this is the policy intent, you'd need to isolate the impact of CERB and determine how that impacted the GIS and then figure out when you're going to give those amounts. Are you going to give them all at once to the extent that you're going to provide an offset? Who will that be given to, and what happens to individuals, for example, who may have received CERB and then paid back CERB a little bit later? We did have a lot of people who did pay back the CERB afterward.
There are all kinds of complex data issues, and you want to try to alleviate the situation rather than make it worse. Therefore, I would say that in moving forward, you need to be very careful to get it right.
