When in doubt about anything, ask yourself this: what would Steve McQueen do if he was in your situation?
In this case, he'd probably say no and maybe have a smoke.
You can use the same rule for Chuck Norris too.
DAS Logistics website doesn't show much in the way of information, to be blunt. You may want to have a frank discussion with them about their references. I'd insist on 3 Canadian carriers they've recently used in the last 2 to 3 months on top of whoever they listed on their generic application.
