the narrative of Framers as applied to Canada is simply false
to invoke Canadian "Framers" is to lack understanding of what framed the constitution in America
the framing is in the Declaration of Independence preamble, the frame is that they were overthrowing the Crown
Canada has never overthrown the Crown, Canada is a Confederation founded by bureaucrats
and that wasn't founded on 1 July 1867, but rather not until 25 March 1982
and that founding was by, for, and through the Liberal Party of Canada
it's the Liberal Party of Canada flag, the Liberal Party of O' Canada anthem, a one party state for all intents & purposes
perhaps someday Canadians will have some Framers
that would be whoever goes to war against the Liberal Party of Canada to overthrow their despotic rule
in terms of why the PM is not investigated by a third party, that is because the PM is the Queen's Executive
Westminster Parliamentary Supremacy invests the office of PM with the authority of the Monarch
there is no third party above the Queen, the authority of the Queen is unimpeachable
