Wow, anti-democratic much? If a person's beliefs are not consistent with "the will of most Canadians" they are not entitled to representation? Each vote counting toward representation in legislature (and potentially governance) should be the essence of a representative democracy. 

There continues to be an opposition in the legislature. Typically the party that finishes second or third and is not part of the governing coalition. And if you haven't noticed, in countries in PR it is not rare for a right oriented coalition to replace a left oriented coalition. As well, there are shifts in the composition of coalitions. For example, Sweden was governed by a right leaning coalition for a decade or so and was recently replaced by the Social Democrats in coalition with Green resulting in a very different set of legislative priorities than past Social Democratic led coalitions.

PR is a  more dynamic system than FPTP. A large degree because people are not excluded from representation like FPTP
