In non emergency situations, they are accommodated if they ask for a female  doctor.

However, I recall reading many years ago about a gynecology resident on call in emerg at the TGH (as it was known then) who was reprimanded by the college of Physicians and Surgeons for refusing to call a female resident down to the ER at the  request of the patient ( or was it at the request of the patient's husband?), who happened to be muslim.

The College ruled that he should have  shown "cultural sensitivity" by calling the female resident who was not supposed to be covering emerg, and that he had acted unprofessionally by refusing to do so.
