Where abouts in Canada are you from? Good to see a few other canucks here! Your best bet is to go to a pressure washer (providing it's still safe to drive) and wash off the debris under the body- you'll be surprised at what you find, lol.
The clips should open up if I remember them correctly. JTGH should be around shortly, one of the best for info along with quite a few others I have had the pleasure to meet on here.
After the repair, get the vehicle undercoated for the winters.
