^Sorry to hear about that, P-Sox.

Much love being sent your way.
How can you have an 'unofficial restraining order', though?
That sounds like some jive-talkin', manipulative B.S. if you ask me. Did the cops say that? Because if they did, that's bullshit-- they can't just up and decide who you're allowed to be within proximity of. Only a judge can do that. Don't let them intimidate you with that kinda stuff, its just words.
An 'unofficial restraining order' is an oxymoron anyways, considering the definition of a restraining order specifies that it must be the result of an official court order by a judge.
I mean, I'm not versed in the subtleties of Canadian law or anything, but I've always been under the impression that you're either subject to the conditions of a court-issued restraining order or you're not-- and if you haven't been ordered by a judge specifically, you can do pretty much anything you want provided you're not breaking any laws.
I know nothing about the specifics of your situation, but it seems to me like
you are the one being harassed here.
I've dealt with enraged fathers before, and basically my standard tactic was to tell them, very politely, that I absolutely do not care about their thoughts or feelings regarding any matter, nor will I entertain any sort of discussion with them regarding any matter at any point in time. Then just hang up.
As for the cops, all you should ever say to them is "Sorry gentlemen, I cannot speak to you without my lawyer present to advise me."
Hope everything works out for you, man. Don't let it shake you up, though-- just stay cool and say nothing to anyone about it.
