The guidelines were created with assistance from sex worker support organizations, including WISH Drop-In Society, according to the document. "They were created to try and address the failures of police to listen and respond to the fears sex workers expressed about their missing friends, colleagues and family members," said Gillies, a former sex worker. "I fear the changes made will further undermine sex workers' access to justice and safety," said Krüsi, who led a 2020 peer-reviewed study on violence against 367 Metro Vancouver sex workers between 2010 and 2017. "It marks a complete erosion of supports that were implemented for sex workers in the wake of a serial killer," she said. The changes come as city services supporting sex workers in Vancouver have been reduced.
