Another very significant reason is that in Canada party discipline for Members of Parliament is heavily enforced.
In a majority government situation (as is the current case) it can have the affect that if the Prime Minister wants the legislation passed then all party members will be instructed to vote for it and it will pass. An MP disobeying the party is a controversial event. In the USA we saw support for SOPA/PIPA drain away as individual members of the house/senate abandoned support, but I feel that that situation is less likely to happen in Canada.
Most of the votes have the Conservative majority solidly on one side and everyone else on the other. It's nearly impossible to stop or alter legislation that Mr. Harper wants passed.
I think this is the single greatest problem with Canadian politics. So many voters now don't even know who they are voting for. They simply walk into the polling station and check the name beside the party they want to represent them.
The concept of a MP is almost pointless because they are usually not representing their constituents. For controversial issues like C-11, ACTA, etc all party members are usually forced to vote a certain way when these issues are the ones were disent is actually the best possible thing for a truly democratic society.
It would be interesting to see what would happen if you didn't identify the party the candidate was associated with on the ballet and no one at the polling station was allowed to provide this information. Would people vote less? Would they actually learn about the candidates more?
They still take bills to committee for review and amendment in a relatively functional process. Further, the bill has to undergo review by the Senate before it is passed. You can write your Senator and the Senate committee to reconsider the egregious clauses.
An other major factor is the current conservative government. It has already taken unilaterally decision on subject like "hand gun register" and "omnibus law" despite the strong disagreement of experts, the public and even potential lawsuit from the province. If the prime minister wants C-11 to pass, it will pass.
