In a statement of claim, Sandy Sanderson says a stage fixture struck him while he was loading his truck during the summer concert.
He then suffered an abdomen laceration and subsequent infection, trauma to his right thigh, skin nerve damage and stress disorders, according to the claim.
Sanderson is seeking $100,000 for "pain and suffering, loss of enjoyment of life and loss of amenities" due to the injuries from the stage collapse.
Sanderson is also suing Mega Stage Inc., which supplied and installed the festival's main stage, and Groupe Berger, its parent company.
The stage collapsed during the July 17, 2011, storm. A Ministry of Labour investigator found the stage had not been properly installed. Bluesfest has since switched stage companies.
Nobody was killed, but several people were treated for injuries.
None of Cheap Trick's musicians was injured.
The Illinois-based band formed in the early 1970s is known for hits such as I Want You To Want Me, Surrender and Dream Police.
