That's another problem. I assure you that we do send information kits to all the work camps. Are they posted? Elections Canada does not have control over that. Many of these camps are not accessible, and it is not always practical or feasible to go and check. In any event, these information kits are sent to the managers of all the camps identified.
You raised the issue of people who want to vote on election day. The act stipulates that if you register to vote by special ballot, you cannot change your mind afterwards. Even if the circumstances have changed, once you have registered to vote by special ballot, it is impossible to vote on election day.
