If it's a van, I suggest G. Zavitz, K.A.M. Trucking (not the other KAM - the one from Wainfleet or somewhere), E.G. Gray, Cavalier, Highland and even Mortrans is worth a call. Not sure if Flexmor gets that way. Also try Polestar and Normandin.
You could try ITS and SLH, provided that they aren't powered out by their own freight. I was also thinking someone like Transport Jean-Francois or one of those guys who runs MA/VT/NH and doesn't mind going into Ontario. KBD comes to mind too for some reason.
