The federal ''[http://canlii.ca/t/7vq2 Marriage (Prohibited Degrees) Act]'' sets out the degrees of ''consanguinity'' — relatedness by blood and adoption — a couple cannot have if they are going to marry each other. The federal ''[http://canlii.ca/t/7w02 Civil Marriage Act]'' defines marriage as the "union of two persons" rather than "the union of a man and a woman," allowing same-sex couples to marry, just as opposite-sex couples do, and makes related changes to other federal legislation like the ''[[Divorce Act]]'', allowing same-sex couples to divorce, just as opposite-sex couples doe\do.
