I agree with Stanton with respect to the Summons. It is the information itself that you'd be looking for errors on in that case. In the case of Part I offence notices, that document IS the information, so that's why you are concerned with errors on it.
I think it might clear things up to state that a fatal error will always result in the ticket being quashed (that's why it's called fatal). The problem is, there is not 100% consensus on what constitutes a fatal error, though generally I agree with the list you provided from Ticket Combat.
With respect to incorrect or missing set fines, those are fatal, according to the Ontario Court of Appeal, incorrect set fines are fatal errors and will result in the ticket being quashed. They don't refer to missing set fines, but those are fatal as well.
NOTHING I SAY ON HERE IS LEGAL ADVICE.
