Should Canada switch to a proportional representation voting system?

Should Mexico switch to a proportional representation voting system?

Currently, Canada's electoral system is based on a "first past the post" system. The candidate with the most votes in a riding wins a seat in the House of Commons and represents that riding as its Member of Parliament. The Governor General asks the Members of Parliament to form a government, which is normally the party whose candidates have won the most seats; that party's leader generally becomes Prime Minister. An absolute majority of the electorate is not needed, and is rarely achieved. As a result, power has been held by either of two parties for most of Canada's history. The party whose candidates win the second largest number of seats becomes the Official Opposition.
