Canafa and us only.
Okay thank you.
So you asked "Do you acknowledge that in north america today, all that's required to be recognized as trans is to self identify and start living as your identified sex. It is NOT required by law to have a doctor sign off, nor have a treatment plan in place to start transition."
I'd first like to point out that despite how you mean the question to be, my initial answer would be no, simply because there are Trans people who - with or without doctors and other documents - who are told they're not, that they fake it, etc, and aren't accepted as Trans.
Also, not all Trans people choose to transition so an already small community narrows when that comes into play. Usually the decision to transition, as I understand it, depends on the severity of a person's dysphoria, IIRC.
That aside, in a way you are right - you don't need anything to say you're Trans, just like I don't need anything to say I'm Bi. That is just who I am, and just who they are.
That said, in order to be ACCEPTED as Trans by the Government, you DO, depending on where you live, need documentation to do things like change your gender on your birth certificates, your passports, etc. And if you ARE going through transition, you DO need to have certain criteria met before it's even a thing.
And as it varies from province to province, state to state; do you want me to put up every rule for every place?

Might not have exactly what you want but if you want it expanded on, say so.
