A published composer and arranger, he primarily performs and records freelance or as leader of his own ensembles while adjudicating and teaching master classes, music camps, and private students. He also manages PoteSmote Music; booking and organizing various ensembles for public and private events. Coach to the Advocats, a pro-am big band, and facilitator of a regular jazz workshop, Peter is also part-time faculty at Upper Canada College.

Peter's primary instruments are saxophone and flute. His interests lay in the historical evolution of Jazz and popular music and the ever-increasing influence of other musics such as Latin and World Beat.  His first CD 'Caliente & Cool' has these elements; the band's second, somewhat seasonal release 'Yule Like This' explores them further. The recently released 'Blue & Green' is a 'live in the studio' recording of the Latin quartet. PSQFunk explores the influence of electronics and ampification on jazz. 'Live and Then Some' is a compilation of live tracks from various venues such as JazzFM's Science Centre series.

His playing, compositions and arrangements can be heard on a number of recordings besides his own, including:
Heather Bambrick, Anita Perras, the Full Count Blues Band, Freefall, Grace, Nazka, Cassava, the Tokyo Giants, and Adrian Luces. 

Peter Smith also performs freelance with other artists, notably: 
Colin James, Heather Bambrick, and the Full Count Blues Band.
