It's interesting that this committee is made up of the voice of Canadians in the last election, mostly. The representation you see here is the outcome of the way Canadians voted in the last election.
Why we wouldn't want that to manifest in Parliament writ large is an interesting question. Minority parliaments have been far more productive over time, in terms of what Canadians want and cherish. Let me run through a quick list that I'm sure you're familiar with: public pensions, employment insurance, the flag, the Accountability Act, post-secondary funding, bilingualism, health care. These are all things that I think Canadians cherish quite a bit and are all the result of minority parliaments, which again would be much more likely out of systems that are called proportional.
Why be so opposed to an electoral system that would produce, often, governments that have, in Canadian history, produced better results for Canadians?
