Trisha became more vocal in speaking out about the abuses of the sex industry after writing about the 2006-2007 murder trial of convicted serial killer Robert Pickton—most of whose victims were women in prostitution and many of whom were known to Trisha. In 2009 she founded EVE (formerly Exploited Voices now Educating), a volunteer, non-governmental, non-profit organization composed of former sex-industry women dedicated to abolishing prostitution as a form of violence against women. She is a leading activist in the campaign calling on the Canadian government to reform its prostitution laws so that women in prostitution are decriminalized and provided with much-needed services, while sex buyers, pimps and brothel owners are criminalized.
