Florence, I think at least that Canada in general is moving forward on this issue.
Here in the US, in the federal prison system, we had reached a point where case-by-case evaluation had become the norm, and where trans women were often incarcerated in women’s prisons.
However, the rise of Trump and the far right have put a stop to even that limited progress.
New directives issued to the Federal Bureau of Prisons ensure that almost all trans women from here out will be housed in men’s prisons.
I think you’re very right, though, to point out that over-incarceration and the violence inherent in the prison system are root causes that must be addressed.
