To be fair, “keep the peace and be of good behaviour” does include more than just a criminal offence, but generally it's interpreted to mean perhaps violation of a provincial enactment, so it wouldn't go so far as to include what used to be “incorrigible behaviour”.
If you could think of wording that would better capture that idea, we certainly wouldn't be opposed to that. That's our intent--simply to ensure that this youth would not continue to commit criminal or other types of quasi-criminal behaviour.
