 The Constitution Act, 1867, however, leaves many royal duties in Prince Edward Island specifically assigned to the sovereign's viceroy, the Lieutenant Governor of Prince Edward Island, whose direct participation in governance is limited by the conventional stipulations of constitutional monarchy.The role of the Crown is both legal and practical; it functions in Prince Edward Island in the same way it does in all of Canada's other provinces, being the centre of a constitutional construct in which the institutions of government acting under the sovereign's authority share the power of the whole.It is thus the foundation of the executive, legislative, and judicial branches of the province's government.
