The  opposition  forms what is called a shadow cabinet  which  is made  up of members of Parliament appointed by the Leader of  the Opposition.  The  shadow  cabinet  watches  and  criticizes   the ministers  of government. They want to show Canadians  that  they would  be  a  better  cabinet if they were  the  government.  The opposition  waits  for  the  right  moment  to  make  motions  of nonconfidence  against the government in the hope of  forcing  an election. If the motion is carried, the government either resigns or calls an election.
