CP ExpressWay piggyback at Dorval

Every time I've rode past this area, there's been a lot of traffic on the combined CN/CP rail corridor passing near Montréal--Pierre Elliott Trudeau International Airport.
This year, I actually had a convention in a nearby hotel, so during a late-afternoon meal trip, I stopped by the Dorval VIA station to see if I could catch some of this traffic on video. Well, I did get one of CP's ExpressWay trailer trains, a consist of articulated 5-unit flatcars carrying a variety of trailers which probably never set foot in the US. For that matter, I don't think the ExpressWay flats ever leave Canada, do they?
