Based on testimony you've heard before the committee and on briefs I've read about the concerns in respect of the lack of inclusion of gender expression in the definition, it is my understanding that the goal would be to avoid opportunities for avoiding criminal liability by simply saying they weren't really trying to change a person's identity; they were just trying to reduce certain forms of expression.
We know that reducing non-cisgender gender expression often forms part of conversion therapy that's aimed at changing gender identity to cisgender. From the witnesses who have come forward and raised this as a concern, I consider it to be an evidentiary issue.
My understanding is that this amendment is trying to address that evidentiary issue in the same way that the other branch of the test, in respect of non-heterosexual attraction and sexual behaviour, is intended to address evidentiary issues associated with proving that a particular conversion therapy intervention is aimed at changing sexual orientation to heterosexual.
