I think the biggest concern about the legalization of prostitution is human trafficking. In every jurisdiction where they have legalized prostitution, the explosion of human trafficking is well documented.
For example, when Germany legalized prostitution, there was an influx of women from South America, and then later, when the Berlin Wall fell, all of these Third World women living in eastern bloc countries were brought into Germany.
The same thing happened in Australia. In Australia, there was an explosion in human trafficking. Apparently there was a large influx of Chinese prostitutes because many of the business people, the procurers of sex—these pimps, now businessmen because it's all legal in Australia—brought in women from all different countries.
That is the biggest fear. Human trafficking is insidious, and I think it's recognized, and well recognized in Canada, that it is unlawful.
