There was a story in Calgary or someplace a while ago, where someone didn't keep the keys safe, so the car was stolen and damaged. Lots of stories of staff damaging vehicles, too.
There are many reports of young, poorly supervised staff being left in charge of vehicles - this could be why customers' property is so often damaged or not adequately cared for.
I'd have to say that, no, you can't trust CT in this way.
Lots of other ways you can't trust them, either. Have a look around this site - see how many ways there are!
