All we needed was a current vacination record. We were ask at the border station, but he didn't need to see it. It seemed they were more concerned about a weapon than anything else. Since we are from Texas and I have Vietnam Veteren Plates on my vehicle, they were sure I had a weapon and they searched everything, but I had read the regulations and even told the guard. They were polite and neet and possible disappointed. We had a great time in Canada for our first experiance and I recommend knowing what the conversion rates are. The credit card companies will charge you a fee for any charges you make. Have a good time!
