Petroleum products, industrial chemicals, salt and grain dominate the cargo profile of Sarnia, the Great Lakes port at the heart of Canada's "Chemical Valley" on the St. Clair River. The Sarnia-Lambton region concentrates roughly 40% of Canada's petrochemical industry, with around 60 refineries and chemical plants fed mainly by pipeline carrying crude oil, natural gas and ethane. Lake shipping moves refined and bulk products, building on a harbour first dredged for grain elevators back in 1927. Seaway draft limits — a channel of around 4.9 m — keep traffic to lakers and smaller vessels, and container or international liner services are not confirmed here. Hinterland distribution runs by road, rail and pipeline into southern Ontario. Shippers needing containerised or ocean-going options should look to Hamilton or Windsor.
