If we're talking about those who are convicted, the judgments of the courts are public. If we're talking about the naming and shaming you find in different countries or in some states in the U.S., that is something different.
Naming and shaming may or may not work. It depends. Without any court judgment, it's also very tricky, because you may have a taxpayer receive a notice of assessment for $100,000 who doesn't owe anything, because the CRA did not know some type of information that allowed the taxpayer to bring it to zero.
If you're talking about a court judgment, that is already public.
