Hello

I am planning a trip to both Toronto and New York this April. I will be flying into YYZ firstly and flying back to the UK via EWR/JFK. To get from city to city i will be traveling by train across the border. What kind of immigration paperwork will i need (ESTA etc..) for all legs of the journey, i am traveling on a full British passport. Also can i expect any aggravation when crossing the border from immigration officials.

Thanks
Matt
