Tim Dyer rhymes off the hidden channels, remarkable campsites and hazardous shoals of Georgian Bay, a UNESCO World Biosphere Reserve, the way an urbanite might offer downtown driving directions. For nearly three decades, Dyer has guided and outfitted sea kayakers on Georgian Bay—the “Sweetwater Sea,” as 17th-century French explorer Samuel de Champlain memorably put it. For Dyer, each island of polished granite and windswept pine of this freshwater paradise seems to hold extraordinary memories for him and his family, who have poured their collective passion and energy into Parry Sound, ON’s White Squall Paddling Centre.
