Canada paternity tests

Has anyone done a prenatal parter it's test in Canada? I would like to know costs, places, was it intrusive ? Any experiences anyone has with this. Since being date raped about 7 days before my posotive opk my husband and I have talked and are looking Into this option. We don't want to wait 9mths to see. And we need to be prepared because if it's not his one I can't raise the child I just can't for more than one reason and two the adoption agency or adopting parents we feel should know about the assholes past so they can work with. Child to ensure they haven't inherited any of his traits :(
