The City of Thunder Bay was established in 1970, by the amalgamation of the Cities of Fort William and Port Arthur, the Township of Neebing, and the Township of McIntyre. Suggestions of amalgamation had been made for decades; the process began in the mid 1960s and culminated in a provincial Act.

The region's settlement by Europeans had begun during the fur trade in the late 17th century, and increased significantly in the 19th century, which also saw the establishment of Municipalities of Fort William and Port Arthur. The name "Thunder Bay" is the longstanding name of the bay on Lake Superior, framed by the Sleeping Giant Peninsula. The name "The Lakehead" also frequently used, refers to the location at the beginning of the Great Lakes shipping route.

Thunder Bay as a City has been shaped by industry: mining, forestry, and the shipment of grain from Western Canada through the St. Lawrence Seaway have all been key to the local economy.

Statistics Canada estimates that as of July 1, 2024, there were 133,063 people living in the Thunder Bay Census Metropolitan Area.
