Seriously, I wonder if the hospitals in question could just quit providing OB-GYN services.
I don't have the whole slate of facts on that, but as I understand it, that's exactly what happened in Ontario and maybe throughout Canada decades ago.
My own OB/GYN here in East Tennessee is a Canadian, used to practice in Ontario but was told he had to get out of his specialty if he would't do abortions. Thatr's why he came down to TN. He told me (years ago) that NO CATHOLIC HOSPITAL in Ontario is allowed to provide gyn services. And they cannot be licensed for matenity.
