Hi Racataca,
McGill University - Dominates the centre for Research on Brain, Language and Music - http://crblm.ca/ - this is the largest network of people working on the intersection of music, language and cognition. I don't know if you'll find a larger concentration of people working in your field or specifically interested int he neural correlates between language and music cognition. Caroline Palmer is a psychologist there who works on prosody and sequence production in music and language. However, the Dec 1st deadline for Psychology just past. If you speak French you can also access the CRBLM through the Université de Montréal and Université de Quebec a Montréal (UQAM), or in English through Concordia University - though only via Psychology since there is no PhD in linguistics at Concordia.
