What happened to diplomacy? What about having a dialogue rather than going to lawyers? Is it possible this was accidental rather than purposely done?
The idea you hire two lawyers, one in the US and the other in Canada at this stage is insane IMO. How have you been damaged? Do you have a track record of stock sales to show in court therefore establishing a value of your work?
Before you go farther I would suggest you talk to someone at the college and find out what happened. Try to come to some type of agreement that is fair for both parties. If you cannot, then you may want to talk to an IP attorney.
