INEOS Sarnia

On December 17, 2025, INEOS Styrolution announced the safe and complete decommissioning and closure of its Sarnia site, marking the end of more than eight decades of industrial and community history.

While the closure of the Sarnia site marks the end of an important chapter, INEOS Styrolution remains deeply appreciative of the men and women who built and sustained this operation over the decades. We thank every employee, past and present, for their commitment, professionalism, and contribution.

To the Sarnia community, we offer our heartfelt thanks. It has been our privilege to be part of this city’s industrial and social fabric for more than 80 years.
