Sarnia History
Before European contact, the area around Sarnia was home to Indigenous peoples, including the Ojibwe and Odawa nations.
The first European to explore the area was the French explorer La Salle in 1701, though significant European settlement didn’t start until the early 1800s. The region became part of Upper Canada (later Ontario) after the British took control following the fall of New France in 1760. After that, British settlers came to establish farms. The British built a military road, the London and Port Sarnia Road, which played a role in the town’s growth.
One of the key factors in Sarnia’s development was the establishment of the Imperial Oil Refinery in 1853, which marked the beginning of Sarnia’s transformation into an industrial center. Over the years, the city became a hub for petrochemical and refining industries.
