The Commonwealth of Nations is a voluntary association of 56 independent countries, most of which were formerly part of the British Empire. Member states, including Canada, share historical ties and commit to common values including democracy, human rights, and the rule of law. The British monarch (currently King Charles III) serves as Head of the Commonwealth, a ceremonial role. Commonwealth activities include the Commonwealth Games, scholarships and exchanges, and cooperation on development, democracy, and trade. Canada's Commonwealth membership connects it to countries across Africa, Asia, the Caribbean, the Pacific, and beyond. Participation is voluntary—some former British territories have chosen not to join.
