Beware that the ET flight is one of the most prone to delays. Also, on some mornings it arrives around the same time as TG, QR and SK from EWR. If you have Canadian passports, you can'ẗ use the EU line, which means that you may end up in line behind lots of Americans, and some Asians and Africans who need visas. I would say a worst-case scenario is 30 minutes in passport control.
