Martin began his tenure as Principal Concertmaster of the Los Angeles Philharmonic in 1995. The recipient of various grants and awards in his native Canada, he graduated with honors from the Montreal Conservatory at the age of 18 and then moved to Philadelphia to pursue studies at the Curtis Institute of Music. In 1986 Chalifour received a Certificate of Honor at the Tchaikovsky Competition in Moscow; he was a laureate of the Montreal International Competition the following year. Since then he has concertized extensively, playing hundreds of concerto performances from a repertoire of more than 50 works. He has appeared as soloist with conductors such as Pierre Boulez, Charles Dutoit, Christoph Eschenbach, Sir Neville Marriner, and Esa-Pekka Salonen. Outside the U.S., he has appeared as a guest soloist with the Auckland Philharmonia, the Montreal Symphony, the Hong Kong Philharmonic, the National Orchestra of Taiwan, and the Malaysian Philharmonic, among others. Chalifour began his orchestral career in 1984 with the late Robert Shaw and the Atlanta Symphony, playing as Associate Concertmaster for six years. Subsequently he occupied the same position for five years in the Cleveland Orchestra, where he also served as Acting Concertmaster under Christoph von Dohnányi. While in Cleveland, Chalifour taught at the Cleveland Institute of Music and was a founding member of the Cleveland Orchestra Piano Trio.
Chalifour is a frequent guest at several summer music festivals, including the Sarasota Festival and the Mainly Mozart Festival since 1989. Maintaining close ties with his native country, he has returned there often to teach and perform as soloist with various Canadian orchestras, most recently with the Vancouver Symphony in the 2010/11 season.
