Episode notes
History Shows Floor Crossings Are Routine
- Floor crossings are historically common but vary in public reaction depending on timing and effect on parliamentary math.
- Gerald Butts notes over 300 crossings in Canadian history, averaging two a year, but recent ones draw more scrutiny as they move the government toward a majority.
Don’t Force By-Elections For Every Switch
- Resist mandatory by-elections for every party switch because they are costly and disruptive, especially in a minority parliament.
- James Moore highlights multi-million-dollar costs and suggests political accountability will occur at the next election instead.
Keith Martin’s Stepwise Floor Crossing Model
- Keith Martin set an example by sitting as an independent, consulting constituents, then running for a new party nomination before formally joining.
- James Moore recounts Martin's stepwise approach as a model that reduced cynicism around switching parties.
