I'm so glad you asked this question. This was the work of my master's degree.
I submitted a position paper to the federal ombudsman for victims of crime specifically on this issue. It is available on their website.
The answer is 100% that trafficking victims need very specialized housing supports. Generally speaking, the housing supports that they require are at minimum for two years, which is very different from what women who are fleeing violence require. They have experienced multiple levels of coercive control. Usually there are histories of childhood abuse, domestic violence, organized crime and gangs. As a result, those trafficking victims require very specialized supports. There are some examples of best practices in Canada that are highlighted in the study that I did for the federal ombudsman for victims of crime.
