I am no expert. I am especially NOT qualified to evaluate and give an opinion about any particular individual's case. As noted in the post you quote (which was made many years ago), there are many variables, not all situations are the same. The details in your specific case are what matter.
I do not how the peace bond in your situation affects you. It depends. At this stage you can either follow the directions you get from IRCC and respond to all requests accordingly, and see where things go, OR you could pay for a consultation with a lawyer to review all the relevant information and give you an opinion about what to do next.
That said, the peace bond itself will not likely resolve questions, IF there are questions. Generally a certified copy of the official court records will provide IRCC with the information it needs, IF IRCC needs more information.
CAUTION: Sometimes an active peace bond means a criminal case is still technically pending, the completion of the terms of the peace bond a condition for whatever final disposition is provided for. This is NOT always the case and maybe not even usually the case; again, these things vary considerably. But if, for example, if there was a criminal charge for a hybrid or indictable offence, and it is still technically pending, pending the completion of conditions such as those prescribed in a peace bond, that could constitute a prohibition and, more problematically, should have been disclosed in the application (disclosing what resulted in the peace bond more than just the fact of a peace bond). If you are certain there is NO outstanding criminal offence charge (that if there was a criminal charge, for example, it has been conclusively discharged), there should be nothing to worry about. If there was a conditional discharge, unless all the conditions have been completed satisfactorily (which most likely means that the terms of any accompanying peace bond are completed, done), so that the discharge itself is FINAL, I do not know whether there might be an issue -- main thing is whether there is a criminal charge involved and if so, what that is and what the precise disposition of it is. The latter would be part of the official court records.
