That's just not true IME and this thread seems confusing to me! Most big Canadian airports have transborder sections (which only go to the US) which have a duty-free section which I have taken advantage of.
I remember these checks from Asia and Europe for a year or two after 9/11, but haven't had an issue since when transiting through the US - certainly not a bottle of water over 100ml! This includes LHR and PVG in the last year.
