We will only know if the government makes the information public. The idea of CEWS wasn't to make companies profitable, it was to allow them to keep their employees without going broke.
After taxes are filed with CRA next spring, a bunch of money could be taken back from companies who didn't need it. I have no idea what the formula is for these programs. Sooner or later a lot of this stuff is going to come out.
I get the need to rush the programs, so it's understandable that for at least the first 2-3 people will get things they don't deserve no matter what was done. But a few months is enough time to realize major errors and figure something out a bit more nuanced. It's not enough time to develop and implement a complex program but it's enough to develop something that's better than something rushed out ASAP.
