Explore the ancient shores of Lake Superior!
This rugged landscape will serve as the terrain of this amazing event.

Known as one of Canada's greatest 'outdoor cities', Thunder Bay is a culturally diverse city filled with exciting shopping, sightseeing and entertainment. The city takes its name from the bay at the head of Lake Superior and is considered the sunniest city in eastern Canada!
