So a bawdy house would only a be bawdy house for the buyer, not the seller? It wouldn't make any legal sense, (and that's why it's still illegal for a prostitute to be a found-in in Sweden). They would have to be caught in the act, like in a bust. First, the cops would have to get a search warrant to enter the premises of a sex-worker, an innocent person before the law, before anything illegal took place. Would a Justice of the Peace issue a search warrant to enter the premises of a person who is not suspected of doing anything wrong, and against her will? Starting to sound like a police state. The possibilities keep growing. If it was at all possible, imagine that the cops assumed, but no reasonable cause, that the sex-worker smokes pot in her place; they would just have to get a search warrant in order to bust a john, and if that doesn't work, they can arrest her once inside with possession of pot. Lawyers would have a field day using the Charter of Rights.Nothing stopping them from enacting bawdy house and solicitation laws so long as they exempt the escort from prosecution. And you are underestimating the ability of police to nail people for prostitution offenses. Catching you with your pants down with a known prostitute and money on the dresser, it won't matter what you said.
No, application of the Nordic Model would be a can of worms in Canada. They would have a better chance of enforcement if money for sex was illegal for both parties. But It would be interesting to know how they would do it, if they did try, though.
