There was a time before the changes in the law, in 2006 or 2007, that it was much easier to vote without ID. People often would show up even on election day and register. Although I have not actually read the report, I understand that at one point under that old regime there were very few constraints on ID. You would think fraud would be rampant based on the premises coming from the other side of the table.
There was at least one investigation by Elections Canada into a riding where there were complaints that about 10,000 people had signed up on election day. Did Elections Canada look into that and discover fraud?
