For Transgender Clinical Services please note that we are unable to take on any new patients at this time and our waitlist is also closed. If you are looking for care, please ask your family physician if they will prescribe - they can download the guidelines from Sherbourne Health Centre. You can also contact Rainbow Health Ontario as they keep a listing of all health care providers who are accepting new patients for transgender care.
