Thunder Bay’s name is the result of a referendum held on June 23, 1969 to determine the new name of the amalgamated Fort William and Port Arthur. Officials debated over the names to be put on the ballot, taking suggestions from residents including “Lakehead” and “The Lakehead”. Predictably, the vote split between the two, and “Thunder Bay” was the victor. The final tally was “Thunder Bay” with 15,870, “Lakehead” with 15,302, and “The Lakehead” with 8,377

A large formation of mesas on the Sibley Peninsula in Lake Superior which resembles a reclining giant has become a symbol of the city. Sibley peninsula partially encloses the waters of Thunder Bay, and dominates the view of the lake from the northern section of the city (formerly Port Arthur). The Sleeping Giant also figures on the city’s coat of arms and the city flag.
