Mr. Speaker, there are secret ballot votes already under certain circumstances in the legislation, but it has been proven for years and years that the card-signing system is efficient and people have not complained about it. In fact, as I mentioned in my speech, Unifor and the Air Line Pilots Association said that this was more democratic and less likely to cause people to lobby and force votes.
In the House of Commons on February 3rd, 2016. See this statement in context.
