cRusty also has the ruling on prostitution in Canada wrong, as usual.
Basically, prior to 2013, it was illegal to sell sex, have a brothel, live off the avails of prostitution, be a pimp or madam or advertise sex work, but it was legal to buy sex.
The laws were struck down, and the Conservative government passed a new one where it is illegal to buy sex, but legal to sell it, illegal to have a brothel, live off the avails of prostitution, be a pimp or madam and almost impossible to legally advertise sex work.
It protects the prostitutes from johns without making Canada a sex trafficking hotspot, on paper at least.
