For countries that choose to regulate prostitution, it remains a vexing question: What’s the best way to do it? Canada’s answer, as Colby Cosh writes in Maclean’s, is to “put the concept of prostitution back into the Criminal Code.” He adds: “For decades, we had these leftover Victorian laws against ‘living off the avails’ and keeping a ‘bawdy house’ without any actual ban on prostitution itself. There are economic reasons to legalize sex work, too. According to The Wall Street Journal (paywall), the sex trade contributed £5.3 billion (about $9 billion) to the British gross domestic product in 2014.
