Johnstone Strait
Canada
The Johnstone Strait (Détroit de Johnstone) is a 110 km (68 mi) channel along the north east coast of Vancouver Island in British Columbia, Canada. Opposite the Vancouver Island coast, running north to south, are Hanson Island, West Cracroft Island, the mainland British Columbia Coast, Hardwicke Island, West Thurlow Island and East Thurlow Island. At that point, the strait meets the Discovery Passage which connects to the Georgia Strait.
