The middle class must occupy a privileged position in Canadian politics. Appeals to middle-class voters are a part of every party platform.
The Harper Conservatives talk about hard-working Canadians. The NDP likes middle-class working families. Recently, Justin Trudeau made middle-class Canadians the centrepiece of his victorious campaign for the Liberal leadership.
