Superior Court of Justice Building, Thunder Bay is a former court house built in 1924 by Chief Architect for Ontario Francis R. Heakes. The simple Beaux-Arts building served as a court house from 1924 to 2017.
It had two court rooms and other offices housing legal tenants like Thunder Bay Law Association.
The Superior Court of Justice (277 Camelot Street) and Ontario Court of Justice (1805 Arthur Street East) had operated in separate buildings but relocated to the new Thunder Bay Courthouse (125 Brodie Street North) in 2014. The old court building was sold in 2017.
