In 2002, Edison was awarded an honorary Doctor of Music by the University of Guelph.[5] In 2009, Edison was made a member of the Order of Ontario.[6]
Allegations of sexual misconduct against Edison surfaced in February 2018, prompting both the Toronto Mendelssohn Choir and the Elora Singers to place him on leave pending investigation. Results of a third-party investigation ended in Edison's being relieved of his leadership duties of both The Elora Festival and The Elora Singers, in mid-April 2018. The Toronto Mendelssohn Choir and St. John's Elora also chose to let Edison go based on their own investigation during the spring of 2018.[7]
In March 2019, Edison announced auditions for a new professional choral ensemble called The Edison Singers.[8] For the first three seasons, he plans three concerts (nine performances) and two recordings with Naxos.[9]
