Prime Minister Stephen Harper met with Governor General David Johnston on Sunday and dissolved parliament.
Canadians will go to the polls on Monday October 19th.
The date means it will be one of the longest and and most expensive campaigns in Canadian history.
Researchers believe this could be a close race as voters are likely to believe any of the candidates could be a legitimate Prime Minister.
Harper not wasting any time getting on the campaign trail, leaving Rideau Hall for a rally in Montreal.
Meanwhile Thomas Mulcair in Gatineau, Quebec meeting voters, and Liberal leader Justin Trudeau making an appearance in Vancouver at that city’s pride parade.
Harper is looking to be the first since Sir Wilfrid Laurier back in 1908 to be victorious in four straight elections.
