While I understand your anxiety, in commonwealth Countries they will COMMUNICATE to you if you are not welcome anymore. Once I had to be the adult responsible for a kid in UK who stole from a shop. He had to apologize, was sent back to his home with the formal warning that the next time he wouldn't be welcome in all the commonwealth countries, should that have happened again.

You have nothing to worry about. The police in Canada react to calls in one of several ways:
Once a charge is laid, record of it spreads out of the officer's physical notebook or a book at the station and into an electronic system run by the province, which can be accessed by CBSA. If you have a court date scheduled, or there is a warrant for your arrest, they will know this when you return. This is less likely to keep you from re-entering, and would have been more likely to keep you from leaving. If you're convicted, that is also available to them and to officers of other countries too. But that's not relevant - you weren't even warned!
In your case there is just a note on a piece of paper, kept in case you don't learn from the caution you were given. If you and the other person continue to clash, the note can be evidence at whatever arises from that clash. But it's not in a system that CBSA can access, and even if it was, they wouldn't keep you out because of it. Relax.
