I have had this issue since my 11 year old sone was first flagged by Air Canada when he was only 5 years old. This solution is totally unacceptable as the onus is still on me to have to prove using some assigned ID number I have to keep track of that my son is not the person they think him to be just because he has the same name (a very traditional Anglo-French name too).

 Transport Canada messed this up and they should fix it so that it is completely  transparent to me and my son. BTW there is no linkage to the US system as we can fly out of Buffalo on Delta with no issues. It's just with Air Canada and West Jet. AC actually told me to get an Altitude # for my son and that might help but it obviously won't work for West Jet.
