I quite see the point of a new and more secure d/l. All official documents should be changed every few years to try to keep the counterfeiters at bay. Passports, d/l, health cars, SIN cards, Currency, Immigrants papers etc.
I do not understand this crazy Canadian thing that you should be allowed into a foreign country without a passport, properly issued by the NATIONAL government. If the USA, Canada and Mexico were to implement a specific accord to allow each others citizens to cross the border without showing documents as it is between most EU countries that would be ok BUT then you'd have to have common external rules for who was allowed in to the whole continent... and Canada would not go for that for its own reasons, the US for its own reasons, Mexico might.
