There's a number or programs around the continent that have a focus in music cognition. UCSD, Northwestern Univ, Univ of Texas Austin, Columbia Univ, NYU, McGill Univ... I'm a BM music composition and BS psychology from Univ of Illinois Champaign, and I got accepted to a MM program at McGill. Both Robert Zatorre and Daniel Levitin have labs in Montreal and are McGill faculty.
