I came across this data on the sound recording industry in Canada. The source is TCI Management Consultants and the data looks a little suspect to me. Recording studios in Canada employ 300 people? Seems very low.

The sound recording industry in Canada provided approximately 17,000 full-time jobs in 1998.
