Peterson never left Canada. The reason why they claim him to have left, is because he was always an obvious junkie. The way he talked and the mannerisms he displayed were typical for a high functioning drug addict. As a clincal psychologist he might have had easier access to Ritaline. He hit it a bit too hard for too long and it all came crashing.
Claiming he left the country makes it seem like there was nobody that could help him in Canada, which is simply not true. It absolves him from being an obvious hypocrite and makes him seem like a victim. His daughter didn't book or do anything, just take a look at her. She's a dumb instagram whore and nothing she does is intelligent or smart. She even married a loser and regrets it which is why she copes by posting selfies on instagram (without her husband). Oh and did I mention she has a child by her loser (ex) husband whom she obviously did not love or respect?
There is no way she does anything to help her dad out of her own volition. What's going on is that he's instructing her to write and do all this shit in an attempt to save face.
She's playing along because his books and what not must be bringing in decent money and she gets a part of it or all of it sooner or later.
Peterson used to be extremely overweight, and his daughter is, too, despite being a fitness trainer (?). They are both psychologically damaged, it might run in the family. Which is why they resort to extreme diet forms ("carnivore diet"). Peterson replaced food with an actual drug addiction. His daughter is still kind of fat, she probably binge eats and vomits (bulimy). She'll probably replace this with an addiction to plastic surgery sooner or later.
