Thunder Bayball is a cityball in northwestern Ontario-icon Ontarioball, Canadaball.


Thunder Bayball was born as a 3ball, used by Franceball as fur trading posts under the name Fort Kaministiquia, then adopted by UKball and Canadaball. In 1970, two separate cityballs, Port Arthurball and Fort Williamball, amalgamated to become modern-day Thunder Bayball.

Just outside of its immediate clay on Highway 11/17 stands the Terry Fox Memorial, the exact spot where the runner was forced to stop his Marathon of Hope cross-country charity run in 1980.

Thunder Bayball is also well known for the Sleeping Giant, a rock formation that resembles a man lying down.
