That's not a coincidence. These systems push governments to serve everyone, not just swing ridings.
It's time to make every vote count here too.
Our voting system is effectively a hand-me-down from the UK (where it is likewise bad and contributing to a number of issues). Your comment is moreso about different levels of government, but whether municipal, provincial, or federal, they all use the same voting system, and they all could use proportional systems (yes, including municipal -- across the board the problem stems from single-member ridings causing distortions when they are used to populate larger chambers. STV maps very cleanly onto municipal politics by just eliminating wards and keeping the same top voted # of councillors).
