The Centre For Inquiry Canada has started a national petition campaign calling on the Saskatchewan government to end the practice of opening each session of the legislature with a Christian prayer as has been done since 1905. The Centre is also calling on Premier Brad Wall specifically to cease issuing an official Christian-themed Christmas message in his capacity as premier of Saskatchewan.
Both the prayer, and the Christian-themed message, go against the grain of a unanimous Supreme Court ruling in April 2015 that held that the state and its various agencies and representatives owe a duty of neutrality to all citizens in matters of religious belief or non-belief.
