I'm a little more interested in the table above the one you pointed out, which shows the popular vote. If we had some sort of proportional representation, the Parliament would have looked like this:
Party|Seats (Proportional)|Seats (Actual)
Conservatives|112|124
Liberals|93|103
Bloc|32|51
NDP|54|29
Green|14|0
Other|3|0
Note how the Bloc is over-represented, because they run candidates in only one region. Also note that the NDP and the Greens are under-represented. The Greens in particular; despite getting more than 4% of the popular vote, they didn't get a single seat.
As I mentioned, our current setup allowed the Conservatives to form the government, despite the fact that nearly 65% of Canadians
didn't vote for them!
