Since the mid-1980s, the church has engaged in study and discussion about sexuality, particularly questions related to same-sex attraction, orientation and relationships. During the 2021 General Assembly, The Presbyterian Church in Canada made changes to its theology and practice regarding marriage, permitting people to define marriage either as a covenant relationship between a man and a woman or as a covenant relationship between two adult people. This decision provides Presbyterian ministers with liberty of conscience and the freedom to choose to officiate or not officiate at the marriages of same-sex couples. LGBTQI people (whether married or single) can be ordained and may serve as ministers and ruling elders in The Presbyterian Church in Canada.
