Why would they do that? If it's all out there in the open, then everyone can find bugs/issues and then they'd have to deal with them. Also they'd probably lose a lot of revenue they collect from fines. Personal anecdote about how you don't fuck with the CRA. Back in college in I got "free" room and board for year because I was a resident advisor. When I, an idiot 20 year old, filed my taxes, I did them wrong and under reported by around 1k. First time doing Canadian taxes as a US citizen. A few years later I got a fine for around $5500, which was a huge sum for a college kid working part time. Turns out BC can match the fine levied by the CRA. In hindsight, I would have been better off just not having that job - I think I would have come out ahead. For the rest of the time I lived in Canada I hired a CPA. The IRS is warm and fuzzy by comparison. At least if you screw up, the fine is proportional to the amount you under report. (unless you're super rich...but that's a different thing)
