I saw this interesting report from DW discussing about the possibility of Canada becoming an EU member state. While not impossible they say it's unlikely for now. I for one would welcome Canada with open arms, and if nothing else it's definitely a fun exercise to consider Canada becoming part of the EU. They would potentially be able to live and work in the EU visa free, who knows maybe Rick Steves will soon have a "Best of Canada" tour as part of his European tour offerings lol!
