Sarnia-Lambton sits on the Ontario-Michigan border, at the southern tip of Lake Huron, giving it immediate access to key markets throughout the Great Lakes industrial corridor.

With a vast network of petrochemical and refining complexes, Sarnia-Lambton is known internationally as a significant industrial chemical centre in North America. The industrial base has focused traditionally on the petrochemical and refining sector; today, it is more broadly diversified through significant investments from the automotive, call-centre, engineering, fabrication and power generation sectors.

In addition, building on its established knowledge infrastructure, Sarnia-Lambton is extending its skills and experience to other sectors: alternative-energy technologies and energy use, industrial bio-products, automotive technologies, and value-added agricultural products.

This economically diverse area also supports a strong tourism industry (water, beach, landscape, golf courses, arts scene) and agricultural industry with the production of a variety of crops for fresh markets or for shipment abroad.
