There's almost 100 years between our first 'Constitution' (1867, BNA) and the one in the US (1776). The US had already fought it's own civil war by the time Canada was celebrating our first birthday. Then in 1982, we produced our first made in Canada, for Canadians, Constitution incl the Charter of Rights and Freedoms and Canadians lost out. It was at this point that Trudeau pere removed our Property Rights at the behest of the NDP. Pictures of the US framers, show well dressed gentlemen in earnest discussion. Our talks in 1982 were an all out donnybrook brawl. (Not a great comparison but it'll suit for this narrative.)
The US Constitution has served them well, with minor amendments, for 246 years. Their 'Great Experiment' continues. Our own Constitution? 40 years old and not working. If Canada and our own, made in Canada Constitution, survives the next 206 years, like the US, you might have an argument.
We've got some pretty good myths about ourselves. Rocks, glass houses, that sort of thing.
