He likelihood depends on the severity of the crime (was damage caused or were you just caught cheating on a single account), the MMO's desigre to pursue prosecution, the Canadian/US authorities desire to pursue prosecution and the ease with which they can identify you and prosecute the crimes. That's a lot of variables to deal with.
The charges, if pursued, would be felonies since any less wouldn't warrant an international prosecution. Your first notice that an investigation is ongoing would be a visit from the feds who would stop by and confiscate your computer and all computer realted materials in your house.
Just because the door to my house is unlocked doesn't mean the stuff inside is free.
