Parliament  exists to serve the needs of the constituents.  The constituents are all  those people who  live in the ridings represented  by  Members of Parliament. They include children, senior  citizens, people  on social assistance, people wanting to start a business, people  with  ideas,  people  with worries,  and  people  of  any political stripe. MPs must represent everyone, whether or not the person voted for them. And in fact, in many ridings across  Canada, most of the  people in the riding did not vote for the person who represents them. Because there are more than two political parties in Canada, individuals who receive less than half of the votes in their riding are often sent to Parliament. The opinions of all their consitituents should  be voiced in Parliament.
