How to Fix Canada's Broken Democracy

Federal power in Canada has been concentrated in the office of an unaccountable Prime Minister. This problem developed in two steps. This first step occurred when political parties allowed the party membership to select their leader at a leadership convention. This put the party leader in charge of the caucus rather than the caucus in control of the leader. Originally, the caucus elected the party leader as required under the British Westminster model. To seal this process, Pierre Trudeau modified the Canada Elections Act to require that a political candidate must have their application signed by the party leader.
The second step occurred when politicians circumvented the constitutional conventions that form part of the Canadian Constitution. These conventions were adopted from Great Britain and form the governing principles under which Parliament operates. The conventions are unwritten and cannot be enforced in the courts. The British have never allowed this to happen in their country. In addition, our politicians adamantly maintain the first-past-the-post electoral system that yields fake majorities in more than 50% of elections with only 38% of the popular vote.
To fix our broken democracy, Canada should adopt electoral reform and concordance democracy. These changes would put governance back under the rules of the Westminster model. Government would become accountable and less confrontational. The country would be more united and everyone's vote would count. These changes can be added to our existing political system without any constitutional amendments. Ideally, an elected Senate (which would require a constitutional amendment) would also bring an additional element of democracy to the table. An implementation procedure is proposed that activists can use to bring these changes forward.
