The year 2015 was one for the political history books.
The scandalous trial of Senator Mike Duffy, the ascendancy of Rachel Notley and the NDP in Alberta, a gruelling 78-day federal election campaign and Liberal Leader Justin Trudeau's stunning victory were just some of the moments that profoundly altered the Canadian political landscape.
