Huh. So if I ever want to travel to the UK again I have to renew my UK passport (as a dual citizen). And I suppose I'd have to do that even if I hadn't bothered getting a UK passport over 25 years ago?
> Any Canadian deemed to be a dual citizen of the U.K., either through being born in Britain or by having at least one British parent, is “no longer eligible to obtain an ETA”
