I live in New-Brunswick, and there used to be Clinic 554 in Fredericton which did informed consent, general trans healthcare, and abortions, but they closed down due to lack of funding.
The way it generally works here as per my friends on hormones is you get a letter of recognition from a WPATH-certified mental health professional, and then get a referral to an endocrinologist via your family doctor. Navigating the NB healthcare system sucks for everyone, but trans patients are even more limited.
