Not yet, we haven't ;) But the feds are making noises about electoral reform, committees have been struck etc.

When the (currently ruling) Liberals were in opposition they were all for it, and it was a campaign plank. Now that they've won with FPTP they seem less enthusiastic, there's considerable suspicion the current process is a sham.
