How "democratic" is Canada?

A party needs to capture 155 seats to win a majority in the House of Commons of Canada. The Conservatives won 167 seats, followed by the NDP with 102, Liberals with 34 and the Bloc Qu�b�cois with four and the Green Party with one. Does this majority government mean they can do whatever they want? I know senators are appointed by the Prime Minister and not elected by the citizens. How democratic is really Canada?
