Party-line voting

In Canadian Parliament, almost every MP votes how their party tells them to. But sometimes they don't — and that's when the interesting stuff happens. This page ranks MPs by how often they stick with their party.

Method: for each recorded Yes/No vote, the majority position of each party is computed. An MP's "consistency" is the % of their votes that match their party's majority. Minimum 20 recorded votes required.

What this means

In Westminster systems like Canada's, party discipline is strong by design. MPs are expected to vote with their caucus, and most do. A 95%+ consistency score is normal; under 90% is unusual. This doesn't make low-consistency MPs "independent thinkers" or high-consistency MPs "robots" — context matters. Look at which votes someone broke rank on, not just the number.
