You still dont get it - the OP was not even transiting the USA.
The passport rule in fact, as proven by a person who actually works UA gates, actually a Canadian requirement (because we love beaurocracy and pointless rules) - and has nothing to do with the "good reasons" that you seem to think exist in the USA.
And at last, many have already told you, that it is all about the costs that may be associated, and nothing to do with "good reasons" or "certain security issues"
Think about it logically, the OP was LEAVING the US. If the OP was a "certain security issue" - should the OP not have been identified as such when ENTERING the USA, or when going thru security?
