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.

⚠️ Known limitation: floor-crossers are excluded from this leaderboard. We currently judge votes against the MP's current party, not the party they were in at the time of each vote. An MP who switched parties shows an artificially low score. Fix planned (would require ingesting per-vote membership records). MPs whose dissent rate exceeds 30% are filtered out as likely floor-crossers.
