Port of Sarnia

Sarnia (UN/LOCODE: CASNI), a freshwater hub on the St. Clair River in southwestern Ontario, Canada, serves as a gateway for bulk and liquid cargoes, including petroleum, chemicals, and agricultural products, benefiting from its proximity to North American industrial centers and the Great Lakes‑St. Lawrence Seaway system; the port operates within the America/Toronto timezone, leveraging terminal facilities, deep‑water berths reaching 12.2 m, and rail and highway connections that facilitate intermodal transfers; its geographic coordinates at 42.974536° N, –82.4065901° W position it advantageously for cross‑border trade with the United States, while environmental stewardship initiatives and vessel traffic management ensure safe, sustainable operations amid regional demand.
