On Nov. 4, 2015, Justin Trudeau made his mark on history. The father of three was sworn in as Canada's 23rd prime minster more than four decades after his own dad, Pierre Trudeau, took his seat as head of Parliament in 1968. Justin was surrounded by his loving wife, Sophie Grégoire Trudeau, and children Xavier, 8, Ella-Grace, 6, and 20-month-old Hadrian in Ottawa. <br>Photo: © Reuters
