I fell in a hole at a border crossing in Canada in July 2011 and broke my ankle on both sides. How much can I sue for in BC Canada?

The hole was located where the blacktop ended and the unpaved parking lot started. Cars driving over the blacktop lip have created a hole. Each year they had to fill it in but had not done it when I fell. I was carrying two laptop computers slung over both shoulders, my cat in a carrier, plus pulling 2 suitcases. The sun was in my eyes. I had on a visored cap and was looking for a place to stand so the girl I met on Craig's List could see me. My plan was to buy a car that day. I was entering Canada after a 40 year hiatus traveling. My specialist says I should have pins/screws put in because I fractured the outside lower part of that big round bone. The ligaments are loose now so the ankle is not stable. I am going to get a 2nd opinion from another doctor. In emergency they were undecided about putting in pins and decided not to saying I wouldn't benefit from it. But after an MRI this specialist says I should get it done. I would be out of work for 3 months plus extensive physio.
