City of Sarnia


Living in Sarnia

Welcome to the City of Sarnia, Ontario’s beautiful Blue Water Country. Located on the south shore of Lake Huron, just across the St. Clair River from Eastern Michigan, Sarnia combines small town friendliness and ease of transportation with big city amenities.

Sarnia is a medium sized City with a “small town attitude” located on the southern shores of Lake Huron about 1 hour north of Detroit, Michigan and 1 hour west of London, Ontario. Sarnia enjoys one of the warmest climates in Canada – being adjacent to Lake Huron the climate is moderated year-round with summer temperatures somewhat cooler than other parts of Southwestern Ontario, and winters typically short and mild with minimal snowfall

The City is characterized by a diverse economic base, affordable residential neighbourhoods, an accessible waterfront extending along the shores of Lake Huron and the banks of the St. Clair River and an extensive system of parks, sportsfields, walking trails, arenas and the Royal Bank Centre (RBC) a major spectator sports and entertainment facility, home of the Sarnia Sting. Cultural opportunities in the City abound with libraries, art galleries, theatres, and special events that are offered throughout the year.

Sarnia, Ontario, Canada, the largest City in Lambton County, is located on the shores of the busiest section of the St. Lawrence Seaway System where the St. Clair River joins Lake Huron

Sarnia became a prominent deep water port during the 1920s when many of the shipping facilities that exist today were constructed, including the winter harbour, the elevator slip and the large grain elevators.
