The elections are clean here and there is what you call "voter integrity" You must be on the voter roll and you must show photo ID to vote. When you vote, your name (with your address) is crossed off the list. Simple paper ballot, no machines, no judicial orders to keep the polls open until the vote can be cooked. Poll watchers from all parties are present in polling places. The paper ballots are numbered sequentially and they better match the number of voters crossed off the list when they are counted. It's not that hard.
The problem in the US is that not everybody wants a clean election, too hard to elect democrats that way.
My experience was before photo ID and mobile phones. Every poll had a Bible so that a voter not on the list could take an oath, and the only time there was any acrimony between the poll watchers was during the race to the only phone to report the results to campaign HQ- first to the phone had to buy a round for the rest of us.
As a Yank who has lived most of the last two decades in Ontario, I think that Canada has moved somewhat to the right fiscally and somewhat to the left socially while the rest of the world has stampeded left. I do appreciate Canadian electoral integrity, though the absolute power of party leaders over candidates nauseates me.
