Some see Single Member Plurality (also known as Simple Candidate Ballot) voting as the fairest system, but it has its problems. For example, the winning candidate in a constituency might attract only 45% of all the votes. But that candidate wins because that percentage of votes is higher than the percentage that any other single candidate wins. Such situations often arise: a majority of voters (55% in this example) voted for other candidates and, it might be, against the winning candidate.

Often, when elections are analyzed across Canada as a whole, it is found that the party that forms the Government (because it has won the most number of constituencies) has not won a majority of the votes cast by Canadian voters.

Other variations on the Single Member Plurality system are the systems called Single Transferable Vote (Ireland), Party List Proportional Representation (most nations in Western Europe), and Mixed Member Proportional Representation (Germany, New Zealand, Scotland).

From among other successful candidates belonging to the same party as the Prime Minister, the Prime Minister forms a Cabinet. Cabinet proposes legislation in the form of bills.

The Prime Minister, the Cabinet, and other successful candidates representing the same political party form the Government of Canada until the next election.
