make sure you download 'mr. border' app for your ios/android phone.. the beauty of it is that it ties into the cams showing you the lineup. The 'wait time' data gets old and not reliable but the camera shows a shot up to within 2 mins so it'll give you a visual idea of the lineups for both to USA and to Canada crossings.
