Ineos Styrolution closing Sarnia plant by 2026

A photo of a

Ineos Styrolution has announced the permanent shutdown of its Sarnia, Ontario plastics plant by June 2026. This decision comes amidst ongoing regulatory scrutiny over benzene emissions from both provincial and federal governments.

The Sarnia site employs 80 people, in addition to a significant number of contractors. The company has committed to working with relevant parties for an orderly and compliant wind-down and closure process.

Closure decision

  • Announced on June 11, the decision to close the Sarnia site was described as independent of current regulatory pressures.
  • CEO Steve Harrington stated, “This difficult business decision to permanently close our Sarnia site was made following a lengthy evaluation process and is based on the economics of the facility within a wider industry context. The long-term prospects for the Sarnia site have worsened to the point that it is no longer an economically viable operating asset.”

Regulatory context

  • The plant has faced multiple regulations and orders due to benzene emissions, impacting the neighboring Aamjiwnaang First Nation.
  • In April, the site temporarily shut down after high benzene emissions were recorded.
  • New provincial regulations limiting benzene emissions and air quality standards from Environment Canada have been introduced recently.
  • Ineos Styrolution has claimed that it has been unfairly targeted by these regulations and has not detected emissions exceeding limits.

Health and environmental concerns

  • Benzene, a clear and mostly colorless liquid found in crude oil, is used to make styrene for products like auto parts and food containers.
  • Short-term exposure to benzene can cause neurological symptoms, while long-term exposure is linked to cancers such as leukemia.

This rule applies to all non-unionized employees in Ontario, Alberta, and B.C., whether you work full-time, part-time, or on an hourly basis.

Individuals working “on contract” or as a contractor may also be owed severance pay — given that many employees in Canada are often misclassified as independent contractors.

Calculating your severance pay

Your severance package is based on several factors. These include your length of service at the company, age, position and responsibilities, any bonuses or benefits you receive, and how difficult it is to find new employment.

The amount of notice you receive, or how far in advance your employer tells you about your termination, is also a key factor in understanding how much money you should receive.

Severance can be as much as 24 months’ pay. It’s essential to note that the specific amount can also vary based on the terms of your employment contract.
