Don't you clear customs in LHR so this point is moot? However, I think that this would be the case if you were flying to the US, since you need to pre-clear customs.
That said, does AC offer any Canada - Canada - US routes on the same flight number?

I am confused as to how this could happen.
I thought that if a flight between 2 Canadian cities, continued on to an international city - then all the ongoing passengers to the international city had to disembark at the second city, and then re-embark - I assume that this is a Canadian customs regulation - that is what happened on my flight from Toronto to Vancouver a few days ago - that flight went on to Hong Kong.
If all passengers have to disembark, then obviously, then the AC flight attendants would have had to awaken her up. Or in St. John's, on this flight, the ongoing passengers (to LHR) do not have to disembark?</font>
