Some familiar faces popping up in this thread, hi Steph, hi Kristyn!
I would add some of my own notes/opinions about Sherbourne Health Centre. To be fair, the number of patients have outgrown their resources, however, the care you receive there is as good as the particular health care professional you happen to be visiting. Kristyn, we have the same doc, and I find that if you are patient with him, he will work with you, however green he is

... it's pretty typical with healthcare for trans persons to have to sort of 'teach' the doctor how to treat us. Part of getting quality health care from the Sherbourne, as it is with most of the Canadian health care system, is to learn it, and become your own strongest patient advocate. Talk to the admin staff, befriend the admin staff!, and learn the intricacies of getting appointments that suit your schedule, this info isn't published anywhere.
I've evaluated in my head, the pros and cons of leaving SHC, to get a regular doc in Durham region, closer to where I live, and I just can't imagine, even with SHC's quirk's, getting the same level of care from any other health facility in Canada's overburdened health care system, especially in regards to trans-specific health care. I'll stay with them, and I do find they really do care, just really busy at times. Between my counselor, the desk admins, my doc, and the nurses, they've gone out of their way to help me both pre and post op, dealing with writing letters for the legal aspects of transition (eeek gender marker change!), getting tests ordered, making sure hormone levels are good, even evaluation of some issues I had with my SRS, etc
To Colleen's point... Sherbourne will treat patients outside of Toronto, my address on file with them is from Durham region. I did however start with a Toronto address, so perhaps that is why I'm allowed to stay on with them. It might be worth asking. Ohhh, and Colleen, not sure if it helps you, but my counselor just sent out a list of endo's, and one is in Mississauga just to the north/east of you.... email me on Susan's and I'll send the info to you if you want it.
Take Care,
Melan
