One year after Canadians elected a Conservative majority government,there is one court challenge trying to overturn the results in one riding, Etobicoke Center, which was won by the Tories. The basis for this legal challenge is not allegations of Tory robocalling or fraud, but rather the incompetence of Elections Canada workers who did not properly understand our country's electoral law. The law says that you must vote at a designated poll location on election day, but there is a common misconception that you can show up to vote anywhere of convenience. This can lead to naive (though often well intentioned) election workers attempting to circumvent the law allowing them to vote in the wrong location. Typically this would be done either by an improper registration/revision or illegal vouching.
In Etobicoke the registration forms are either missing or never existed. Allegedly people were also being told at that location that they could vote in the box with the shortest line, and if people were doing so than many were voting in boxes where their name was not on the list; which would require corroborating incompetence by the DROs, poll clerks and poll supervisors in addition to the information/registration officers. Now a Conservative MPs victory is being challenged in court because election workers did not do their jobs properly. The Tory has the most to lose, but make no mistake, it is Elections Canada on trial.
Has a judge ever overturned a federal election result? I'm not sure that you could just void all the results from that specific poll location, throwing away thousands of legal votes because of a few dozen improper registrations/vouchings. Can a judge force a byelection in a riding because workers at a given location screwed up? If that's the case, there's probably 100 other MPs who should be concerned for their jobs. In a perfect world, election workers would know election rules and perform their duties accordingly. Unfortunately when dealing with a large temporary workforce assembled and trained in a short period of time, you are going to get mistakes, in some place more than others. Is this sufficient to force a byelection?
