1. I understand the frustration of the people who have now discovered that they are not Canadian citizens due to a technicality and wonder whether at the time this law was in power Canadian immigration informed people travelling out of the country that they need to sign such a document if they are going to be residing outside of Canada on their 24th birthday? Additionally it would be interesting to know on the basis of which document did they then let them back into the country if they where not Canadian citizens upon return?
2. On the point of border babies. Both Canadian citizens and landed immigrants have equal rights to child support and old age security benefits. However, only Canadian citizens have the right to vote while landed immigrants do not. So how did the Mr. Mallo have the right to vote if he was not a Canadian citizen? It seems that there is a contradiction here.
3. Just for the information of people having fun with dual citizenship (specifically Canadian/US dual citizenship) according to international law when you are in one of the countries of your citizenship that country deems you only its citizen. It is your right to choose exclusively in those countries that you are not a citizen of, e.g. as a Canadian/US citizen you can choose to be treated as a one or the other in Mexico. In Canada under the letter of the law you are only a Canadian citizen and are not recognised as a US citizen and vice versa when you are in the US you are only recognised as a US citizen.
So then is it just fun to enter Canada with a US passport when you have dual Canadian/US citizenship or is it technically illegal?
4. On another point, what is the case with Canadian citizens that do not have machine readable passports? Will they be treated like citizens of the EU that have their fingerprints and photos taken on entering the US? The information given by Canadian embassies in 2006 was that Canada does not issue machine readable passports except in Canada, London and Hong Kong. Additionally they also state that you can only get a Canadian passport in the place of your residence, so if you are working abroad for an extended period of time you cannot get your passport issued in Canada but have to get it from your nearest embassy. Considering the large number of Canadians that work and live abroad it is also something that needs to addressed.
5. Additionally a comment on the posting on terrorists crossing the boarder from Canada into the US. I do assume that each country is still solely responsible for whom it allows to cross its borders. For example if a terrorist lives in some overseas country and travels to the US and passes through US immigration is it the fault of the country he/she came from or a laps of the US customs control? Why should it be any different in the case of Canada.
6. Finally, the main purpose of a passport is as a means of identification outside the borders of the country of your citizenship so I do not see why you should not use it whether you go by plane or on foot when crossing the border from Canada to the US or vice versa.
