A Parliamentary system is one in which an elected parliament acts both as a legislative power, and appoints the executive officers of the government. Oftentimes, parliaments also control the appointment and promotion of judicial authorities as well. Parliamentary systems are contrasted with multi-partite or checks-and-balances governments. The Canadian government is a parliamentary system, with the governor general exercising the rights and powers of the sovereign in the absence of the Canadian (British) monarch.
Parliamentary movements for Cascadia may be paired with monarchism, seeking to replicate a Canadian-style government for Cascadia, or may seek to implement a French or German-style Presidency, where an elected President holds ceremonial and reserve powers for a Parliamentary system, with very little or significant additional political powers.
