Let me first say that once a person demands a particular medical treatment, a physician, in his own professionalism, is not forced to provide that service. He will seek the service that is most appropriate for the patient.
As to the referral, I understand that the situation in rural areas may be difficult, but it is not necessary for a particular practitioner who objects, for conscience reasons, to refer somebody who doesn't share that objection. There are other means of making these referral services available to the population across a province. You just have to put in place an appropriate information system and do it.
