According to the US State Department Trafficking in Persons Report:
Canada is a source, transit, and destination country for men, women, and children subjected to trafficking in persons, specifically forced prostitution and, to a lesser extent, forced labor.
Canadian women and girls,particularly from aboriginal communities, are found
in conditions of commercial sexual exploitation across the country.
Foreign women and children, primarily from Asia and Eastern Europe, are subjected to forced
prostitution: trafficking victims are from China, Hong Kong, Taiwan, China, South Korea, the Philippines, Romania, Ukraine, and Moldova, in addition to other countries and territories. Asian victims tend to be prevalent in Vancouver and Western Canada, while
Eastern European and Latin American victims are trafficked to Toronto, Montreal, and Eastern Canada.
Law enforcement officials report the involvement of organized crime in sex trafficking. Canada is reportedly a destination country for foreign victims of forced labor.
Most labor victims enter Canada legally but then are subjected to forced labor in agriculture, sweatshops and processing plants, or as domestic servants.
NGOs report higher levels of forced labor in the provinces of
Alberta and Ontario, while acknowledging the difficulty of distinguishing forced labor from labor exploitation.
A considerable number of victims, particularly South Korean females, transit Canada en route to the United States.
Canada is also a significant source country for child sex tourists, who travel abroad to engage in sex acts with children.
