As with other mainline denominations in North America, the Presbyterian Church in Canada has been wrestling with social issues and, especially, with human sexuality. In 1998, the Presbyterian denomination prohibited gay and lesbian pastors and denied licenses to preach to these ministers; in 2012, however, that ban was lifted by the assembly. According to the Social Action Handbook, "The Presbyterian Church in Canada recognizes that homosexual orientation is not a sin." "The Presbyterian Church in Canada has never limited the roles of its members on the basis of their sexual orientation. These roles include church school teachers, musicians, youth leaders, ruling elders, teaching elders and members of the Order of Diaconal Ministries."
