Constitutional scholar Phillippe Lagassé argues that as the Succession to the Throne Act, 2013, and court rulings upholding the law, section 41(a) of the Constitution Act, 1982, which requires a constitutional amendment passed with the unanimous consent of the provinces, applies only to the "office of the Queen", but not who holds that office, and that therefore "ending the principle of symmetry with the United Kingdom can be done with the general amending procedure, or even by Parliament alone under section 44 of the Constitution Act, 1982."
