International student coming to Canada, need official diagnosis?

I am an international student coming to North Vancouver, Canada. I plan on getting hormone replacement therapy, facial feminization surgery and electrolysis hair removal.

1.Do I need gender dysphoria diagnosis from a mental health Profesional before I can access these services through msp or private health insurance till my medical service plan gets processed? Can it be helpful or required in any circumstance?

2.Will a diagnosis from my country work in canada?

3.Does the diagnosis has to be from a 2SLGBTQIA+ specialist mental health professional or will my general psychiatrist and counselor do?

4.Any specific forms I need? Will both my psychiatrist and counselor need to provide the diagnosis? One of them? Which one?

Note: I have been going to them for 2 years however for generalized mental health issues including my gender dysphoria but not my dysphoria specifically.
