Most but not all elected MPs are members of political party. After an election (or less commonly a vote of no confidence by the house that does not result in an election) the Governor General asked the leader of the party with the most seats to form a government. That leader becomes the Prime Minister, the most powerful political position in Canada. Canadians do not directly vote for the Prime Minister (unlike in the US for example) but rather the Prime Minister is the leader of the governing party and is usually elected as an MP in a single riding. Some Prime Ministers became party leader and Prime Minister without first (or ever in the case of John Turner) holding a seat. A good explanation is given by Rick Mercer.
