Timothy has a B.Mus from Carleton University and an ARCT in Organ Performance from the Royal Conservatory of Music.  In 2001, he became Associate Organist at Christ Church Cathedral in Ottawa, where he founded and directed the Cathedral Girls’ Choir.  Under his tenure, the choir grew into a first-rate performing ensemble, singing at weekly Cathedral liturgies and regular events involving dignitaries and parliamentarians.  The Girls’ Choir also toured to Kingston, Montreal, Quebec City, Washington DC, England and Belgium. In Europe, they sang services in Westminster Abbey, Canterbury Cathedral and at the Menin Gate in Ypres. 

In 2012, Timothy left the Cathedral to found Chorale Lyrica, a bilingual choral program in Hull.  Chorale Lyrica has flourished and now consists of 4 choirs with singers ranging in age from 5 to 20. A specialist in choral training for youth, Timothy also directs a 90+ voice choir at Pierre Elliott Trudeau Elementary School in Hull, and since 2016 has been Musical Director for the Western Quebec School Board’s MusicMakers event which brings together over 800 kids from across the school board each spring for a massed concert.  

Timothy has also written a number of musicals, including Bye Bye Bytown, which enjoyed successful runs at both Centrepointe Theatre and the Ottawa Little Theatre.  He also loves to write for choirs and many of his choral pieces can be heard on CDs recorded by the Cathedral Girls’ Choir.
