Chapter 345 Section 5 of Saskatchewan’s Bill of Rights (1947)states that “every person and every class of persons shall enjoy the right to peaceable assembly with others and to form with others associations of any character under the law.”

Part 1 of the Canadian Bill of Rights (1960) lists “freedom of assembly and association” as a guaranteed right. This was an ordinary act of parliament, and it has been replaced by the Canadian Charter of Rights and Freedoms, an amendment to the Canadian Constitution.
