I think this should really be an unlimited right. Currently, Canadians abroad are the only subset of the Canadian population who are unable to vote. We have to remember that the majority of these Canadians can't vote where they are.
There are also the practical implications. I know of people who have sought out their MPs in the ridings they used to live in to talk about this issue and who got the message back, saying, “I don't know if I'm your MP, because you can't vote here.” They didn't have anyone to talk to. They don't have anyone to go to for help if there's some issue with the program.
I think it is very important and very fundamental that everyone should have the right to vote.
