• are a practicing member in good standing of the appropriate regulatory body, for example, the College of Physicians and Surgeons of Ontario or the College of Psychologists of Ontario,
• have treated or evaluated you (give your full name) who is requesting the change in sex designation (specify the change in sex designation)
• confirm that your gender identity does not accord with the sex designation on your birth registration, and
• are of the opinion that the change of sex designation on your birth registration is appropriate.

The letter must include your full legal name. You must submit the original letter not a copy.
