Sovereignty is an abstract legal concept. It also has political, social and economic implications. In strictly legal terms, sovereignty describes the power of a state to govern itself and its subjects. In this sense, sovereignty is the highest source of the law.

By 1949, Canada had become fully sovereign in relation to Great Britain. This was due to landmark legislation such as the Statute of Westminster (1931). The Constitution Act, 1982 swept away Britain’s leftover authority. Questions of sovereignty have also been raised by Indigenous peoples in Canada and by separatists in Quebec. The latter, for a time, championed the concept of sovereignty-association.
