How does a Canadian Psychiatrist go about practicing in the USA

Hi all, Theoretically if I wanted to set up shop in the US with Canadian med school/psychiatry training what would I need to do? I read somewhere that American/Canadian boards recognize each other's training? Would I need to write USMLEs? Any insight would be much appreciated!
