One more piece of feedback... Make sure you are searching for the right thing when you are looking for comparable cases.
It's not an exemption to a 5 year bar or ban that you're looking for. That's a misrepresentation ban. That's a completely different situation which has nothing to do with criminality issues. 5 year misrepresentation bans are given when someone materially misrepresent key information in an immigration application (e.g. not declaring past visa refusals). I am aware of some H&C situations where IRCC has given an exemption for a 5 year ban that was given due to misrepresentation. But again, these cases are not what you're looking for.
What you want to be looking for is exemptions to inadmissibility due to criminality.
