Absolutely 100% not. You cannot consent to conversion therapy, because you might be told that it's one thing, but it is ultimately a destructive or hurtful practice, and under Canadian law, you cannot consent to bodily harm in any respect, and that definitely applies. Any consent that someone thinks they're giving to conversion therapy is coerced, because they're being sold a lie if they believe this is going to help them and change their identity, when it is not effective and has been proven to not have any effect.
I went through conversion therapy after the age of majority only because Dr. Zucker was the only one who was allowed by the Ontario health system to prescribe me the gender reforming care I needed. My conversion therapy was coerced for that reason.
