Thunder Bay

Twin ports under the Sleeping Giant

Thunder Bay in brief

Thunder Bay is Northwestern Ontario's largest city on Lake Superior, formed from the older ports of Port Arthur and Fort William. Anishinaabe peoples lived here first; French fur posts came in the late 1600s, and the North West Company built Fort William in 1803.

From town, the Sibley Peninsula's cliffs look like a giant asleep on his back, once voted among Canadians' Seven Wonders. The Terry Fox Monument marks the spot where Fox ended his cross-Canada run.
