Thunder Bay, Ontario - is the most populous municipality in Northwestern Ontario with a population of 108,359 as of the Canada 2011 Census, and the second most populous in Northern Ontario after Greater Sudbury. European settlement in the region began in the late 17th century with a French fur trading outpost on the banks of the Kaministiquia River. It grew into an important transportation hub with its port forming an important link in the shipping of grain and other products
from western Canada through the Great Lakes and the Saint Lawrence Seaway to the east coast. Forestry and manufacturing played important roles in the city's economy. The city takes its name from the immense Thunder Bay at the head of Lake Superior, known on 18th-century French maps as Baie du Tonnerre (Bay of Thunder). The city is often referred to as the "Lakehead" or "Canadian Lakehead" because of its location at the end of
Great Lakes navigation.
