Cosmo Music Repair Shop

In the early 1980’s the Repair Shop at Cosmo Music opened its doors with one technician and a commitment to offer superior craftsmanship and outstanding service and value.

More than 30 years later, and with the same commitment, Cosmo Music operates one of the largest and most prestigious instrument repair shops in Canada. Each year hundreds of schools, students and professional musicians trust Cosmo Music to restore their instruments to like-new playing condition. In addition to customer repairs the shop also maintains a fleet of over 14,000 rental instruments which are used by students across Ontario each year. Led by its original technician, Kevin Rohm, the shop now employs 23 technicians and specializes in all types of wind instruments, guitar and electronic repairs. Cosmo Music has made a significant investment in equipment so that its technicians have access to all of the latest and best tools and techniques to service your instrument quickly and properly – the first time!
