I was just going to add that one of the positive aspects of the pre-registration is that it could be used as a fairly concrete call to action when Elections Canada does conduct civic education activities with youth in high schools so that there's something they can do to be part of the process.
Then other aspects of the bill would then facilitate, for example, the receiving of voter information cards once you're registered, so you would have a piece of ID that you could then take to the polls at the same time.
