@JohnAskew: First question: The Queen (monarch) is the symbolic head of Canada and has no real powers and doesn't really own any part of Canada.

 

Second Question: Currently there is no leader of the Liberal party, just an interm leader until one is selected sometime later this year. Before the son of Pierre Trudeau entered the race, there was some speculation that Mark Carney might run for leader. Since liberal and Conservative parties in Canada are close to the center, Carney could fit in to either party.
