Thanks for the advice. I am still not sure what the answer is though. Will Canadian border officals be able to see this expunged arrest and if so will I be denied entry into Canada? Is there a clearcut answer in general or is it just left up to the particular border officer I have to deal with? Need to know before I spend the money to book the trip
As I said, you are American and white skin, you have much better chances than others. Some time border officials don't even bother to stop Americans to ask questions.
Even they stop you then it also left up to the particular border officer you had to deal with. Many Americans travel to Canada frequently. Do you want to travel by car ?
