This sex worker-led organisation based in Toronto provides support to and advocates for the rights of Asian and other migrant sex workers in several cities in Canada. Butterfly builds leadership skills and capacities of migrant sex workers through a peer-to-peer programme. Its members visit migrant sex workers in detention centres, prisons and court. The group provides legal support and interpretation services, assists with arranging bail and supports deported workers. Butterfly advocates for changes in anti-trafficking policy and immigration laws to make them less harmful for migrant sex workers.
