In my experience with the CAMH GIC for adults, they've been quite good to me thus far. Don't let the fear-mongers dissuade you. I've had an appointment with Drs. Brown and Hucker. The assessing doctors (one psychologist, and one psychiatrist) didn't try any dumb stuff with me, and basically said they were just going to rubber-stamp me. The issue for me is they don't give much notice before you have an appointment. Also, there have been some clerical mixups with my paperwork, which I resolved fairly quickly. As long as you have documentation galore, you should have no issues. Also, OHIP and the CAMH GIC are slow, and lack funding to do anything about it (the clinicians are well aware they lack the resources to actually help), so get into the system ASAP as not to delay your physical transition any more. Sure, CAMH and OHIP are painfully slow, but if you wait, you can have provincially funded SRS (unfortunately CAMH is the only option at the moment).
CAMH isn't what people make it out to be. Prior to my intake appointment, I had heard good things about Dr. Brown, so the only concern was Dr. S. Hucker (not any more) since he co-authored many studies with Dr. Blanchard. My real concern was/is just timing, and how long it will take to finally get my approval/funding for surgery. The only reason I say this is because I work in an environment where SRS will only reduce my anxieties (I'm a swim instructor/lifeguard), so it's very trying. Skin-tight neoprene and/or lycra doesn't leave much to the imagination.

To get in touch with CAMH Adult GIC (I assume you want to get on the wait list), get your GP or endocrinologist to send in a referral for you.
