Lambton County is made up of eleven member municipalities comprising a total population of approximately 127,000 people.  Lambton is located at the southern-most tip of Lake Huron.  The St.Clair River represents the western boundary of the County as well as the Canadian-U.S. border in this area.  There are more than a dozen urban settlements of significant size located in the County, the largest being the City of Sarnia with a population of approximately 73,000.

Although Lambton County’s land area is predominantly rural with a corresponding agriculturally-based economy,  it  is  also host to the largest grouping of petro-chemical industries and refineries in Canada.  Sarnia-Lambton’s “Chemical Valley” extends across the municipal boundaries of the City of Sarnia and the Township of St. Clair.

The twin Blue Water Bridges connecting the Village of Point Edward and the City of Port Huron, Michigan is the fourth busiest international passenger and commercial vehicle crossing in the province and the second busiest international truck crossing in the Ontario. Highway #402 terminates at the Bluewater Bridges.

The Canadian National Railroad passes through three Lambton County communities and crosses into the U.S. via the Paul M. Tellier Tunnel.  This 8.4 metre high tunnel carries more rail freight (approximately 10% of which is hazardous) than any other U.S.-Canadian border rail crossing and is the world’s largest international rail tunnel.  Sarnia is host to Canada’s second busiest international rail yard.

The St.Clair River is a major shipping channel on the Great Lakes and it is a recreational area, source of industrial process water and source of drinking water for tens of thousands of people on both sides of the Canadian-U.S. border.  The St.Clair River flows south to the environmentally-sensitive delta at the Walpole Island First Nations Reserve, the southernmost part of Lambton County.  Lambton also includes  Aamjiwnaang First Nation in Sarnia and the Kettle and Stony Point First Nation in the Municipality of Lambton Shores.
