The long Canadian election campaign was supposed to highlight just how inexperienced Liberal leader Justin Trudeau was and give the ruling Conservatives an ample supply of gaffes to use in attack ads.

The gambit underestimated Trudeau, the 43-year-old son of charismatic former Prime Minister Pierre Trudeau, and, by setting expectations so low, may have helped him instead.

Trudeau's Liberals will form Canada's next government after defeating Conservative Prime Minister Stephen Harper on Monday.
