Some proposals for an independent Cascadia advocate the integration of Cascadia into the British Commonwealth of Realms, adopting the British Royal Family for a Cascadian monarchy. Most Commonwealth proposals would adopt a parliamentary model for the Cascadian government.
Canadian Cascadia[]
The simplest Commonwealth proposal is to simply adopt the Canadian constitutional model for Cascadia. British Columbia would retain its provincial government, while the governments of Washington, Oregon, Idaho, or other provincial divisions would be (re)formed as unicameral parliamentary systems under the crown with Lietenant Governors appointed for each new Cascadian province. The national government would be organized as a legislative monarch-in-parliament, executive monarch-in-council, and judicial monarch on the bench. The legislative would be composed of a dominant lower house of commons, and an appointed senate which is not able to hold of vote of confidence in the government. The executive is composed of a privy council, containing various members appointed for life by the Governor General and a Cabinet containing most government ministers, the Governor General almost always adhering only to the advice of the Cabinet. The judicial would be composed of the Supreme Court, Federal Courts of appeal, Provincial Courts of appeal, and superior and inferior courts thereof.
Under a Canadian-style Cascadian government, the federal government would hold powers not specifically reserved to the provinces constitutionally or devolved thereto.
Other Commonwealth proposals[]
Other proposals for integration into the British Commonwealth Realm would be in the form of a Constitutional oligarchy, where the British monarchy would constitute the sovereign for acceding regions, with other sovereigns for other regions, each one appointing lieutenants to act co-equally as the foundation of government.
