Wikipedia said:The Canada Act 1982 (1982 c. 11) is an Act of the Parliament of the United Kingdom that was passed at the request of the Canadian federal government to "patriate" Canada's constitution, ending the necessity for the country to request certain types of amendment to the Constitution of Canada to be made by the British parliament. The Act also formally ended the "request and consent" provisions of the Statute of Westminster 1931 in relation to Canada, whereby the British parliament had a general power to pass laws extending to Canada at its own request.
The act wasn't passed without opposition
Wikipedia said:In the UK, forty-four Members of Parliament voted against the Act, including 24 Tory and 16 Labour MP's, citing concerns over Canada's past mistreatment of Quebec and Aboriginal peoples (as recalled with frustration by Jean Chrétien in his memoirs Straight from the Heart); overall there was little opposition from the British government to passing the Act.[citation needed] However, new research into documents of the Thatcher government indicate that Britain had serious concerns about the inclusion of the Canadian Charter of Rights and Freedoms within the Canada Act. Part of this concern stemmed from letters of protest the British received about it from provincial actors, but also because the Charter undermined the principle of parliamentary supremacy, which until that time had always been a core feature of every government practising the Westminster system.[11]
So what if opposition was stronger, just strong enough for the bill to fail.
Unilateral declaration of independence for Canada? Republicanism?
