From what I know, prof. Charles Boberg has worked on phonetics and phonology, and he is a teacher at McGill. Howevwe, I have not studied there, so I don't really know what is the dept's main focus. I think that if it is your dream school, you should apply. They would not accept a student if they thought he or she had interests that were too different from their own.
