"My daughter takes her car into CT " - That is mistake #1, never go to Canadian Tire for auto service. I find that they are very incompetent when it comes to repairs. That's why're they're nicknamed "Crappy Tire".
It's okay to buy auto parts from there, just don't get a car serviced there.
At least she's okay. Take the car to any certified bodyshop that you choose and Canadian Tire is responsible for the payment. Let them pay for a rental car as well.
If your daughter didn't suffer any injuries, than you can't sue for anything.
