Sarnia Manufacturing Centre

Shell employee in red uniform factory site

Location: St. Clair Parkway, approximately 10 kilometres south of Sarnia, Ontario, between Froomfield and Corunna.

Employees: 350 full-time employees

Refinery Capacity: 85,000 barrels of crude oil daily

Products: Gasoline, distillates, liquid petroleum gas, heavy oils, pure chemicals, solvents

Originally built in 1952 by Canadian Oil Companies Limited, the refinery became part of Shell’s operations in 1963 when Shell purchased Canadian Oil. The refinery can process up to 85,000b/d of crude oil, which is then converted and refined to help meet southern Ontario’s transportation fuel needs (gasoline, diesel, and jet fuel). The refinery also provides key base materials for chemicals and propane producers in the Sarnia area, including for the Shell Chemical plant adjacent to the refinery. The Shell Chemical plant, which was built in the 1970s, is a key North American producer of IsoPropyl Alcohol - a key ingredient in hand sanitizers, disinfectants, and other medical uses.

Since the refinery’s start, we have completed numerous upgrades, modernized equipment, and added new facilities and technology to meet current and future product regulations and environmental legislation. Shell continues to invest in its facilities to ensure they comply with all new federal regulations and environmental best practices.

In 2002, Shell became the first nation-wide refiner capable of producing low-sulphur gasoline when it started up its second gasoline hydrotreater.

To meet federal regulations for ultra-low sulphur diesel that came into effect on June 1, 2006, SMC signed a 20-year agreement with Suncor Energy Products Inc. which saw Suncor designing, constructing, and operating another hydrotreater. This hydrotreater is used by both Shell and Suncor to reduce the amount of sulphur in our diesel, resulting in environmental benefits for the Sarnia area.

This hydrotreater also allowed Shell to meet tighter gasoline sulphur regulations that came into effect in 2020. As well, in 2020, the refinery converted its terminal to E10 gasoline (gasoline with ethanol) to comply with future federal clean fuel standard requirements.

We continue to upgrade refinery components in order to meet current and future government regulations.

In addition to following Shell's own rigorous health, safety, and environmental management systems, SMC has received the ISO 14001 environmental management accreditation from the International Standards Organization.

As part of Shell's ongoing commitment to sustainable development, we continue to support Lambton County community groups including United Way, Lambton College, St. Clair Township, Bluewater Health, First Nations initiatives, and a number of grassroots environmental projects. Employees and retirees who regularly volunteer with community organizations are recognized by the company through the Fuelling Kindness Grant Program.

Operations and Products

Shell's Sarnia Manufacturing Centre (SMC) refines approximately 75,000 barrels per day of raw crude oil into a range of petroleum products such as gasoline, diesel, jet fuel and various petrochemicals.

Refining is a general term that refers to a range of manufacturing processes that turn crude oil into useful products such as gasoline, jet fuel and various petrochemicals. SMC’s refining processes include distillation, catalytic cracking, thermal cracking and catalytic reforming.

In 2002, SMC added a gasoline hydrotreating process unit and a new flare system to the refinery. The hydrotreating unit enables Shell to produce low sulphur gasoline in line with current federal government regulations requiring all Canadian gasoline to contain no more than 30 parts per million of sulphur.

To meet new federal regulations for ultra low sulphur diesel that come into effect on June 1, 2006, SMC signed a 20-year agreement with Suncor Energy Products Inc. The agreement will see Suncor design, construct and operate a hydrotreater, which will be used by both Shell (which will pay a processing fee) and Suncor to reduce the amount of sulphur in diesel for both companies. Operating one hydrotreater will result in environmental benefits for the Sarnia area.

While refining oil into useful products is SMC’s focus, the majority of site operations are, in fact, the support functions that make the refinery work in an efficient and environmentally responsible manner. SMC’s support functions include product quality monitoring, water treatment facilities, emissions monitoring, process control, pipelines, utilities as well as various raw material and finished product storage facilities.

Emergency Response and Safety

Emergency response and safety are important parts of operations at each Shell facility. Our goals are no harm to people and protection of the environment. To achieve our goals, we have a systematic approach to emergency response and safety designed to protect the community and our employees.

Emergency Contacts

To report an emergency, please call 9-1-1. The Sarnia Manufacturing Centre's 24-hour Safety and Environment number is (519) 481-1455.

Emergency Response

Sarnia Manufacturing Centre (SMC) has an Incident Command System (ICS) that provides effective response to any emergency on our site. The ICS provides a quick assessment of emergency situations allowing SMC professionals to quickly evaluate the situation and mount an efficient and effective response – using either our own resources, or if necessary, our own resources in conjunction with the Chemical Valley Emergency Coordination Organization (CVECO).

Made up of industry, municipal police, local fire departments, provincial police, the City of Sarnia and the St. Clair Township, CVECO is a world-class emergency planning and response organization dedicated to community and industry safety.

Shell is also an active member of the larger community program, Community Awareness and Emergency Response (CAER). Through CAER, Shell works with the municipalities and other companies to address issues and problems that arise from industry working in close proximity to the community. For example, Shell recently partnered with other CAER companies to install an emergency siren system throughout our surrounding area. The siren system will alert Point Edward, south Sarnia, Aamjiwnaang First Nation and Corunna communities about industrial or severe weather emergencies.

If you live in these communities and do not know what to do if a siren sounds, visit the CAER website, or contact us by e-mail.

SCL Pipeline Emergency Response Management System and Emergency Response Procedure

As an NEB-regulated pipeline, SCL Pipeline, operated by SMC, has an Emergency Management System and an Emergency Response Plan in place to ensure preparedness for the unlikely event of a pipeline incident. In the spirit of transparency, and in response to NEB Order MO-006-2016 and NEB Order MO-002-2017, the following links will take you to the Emergency Management System and Procedure for SCL Pipeline.

Community Dialogue/Social Performance

In addition to our work with CAER, we also conduct our own Community Dialogue Program to understand community concerns and promote emergency preparedness. SMC is an active member of the Bluewater Community Advisory Panel, which is made up of local industry and community representatives from Lambton County, including St. Clair Township. The panel meets regularly to discuss local issues and concerns as they relate to public health, safety, and environmental impacts of local industry.


At Shell, safety is our first priority and we strive to achieve zero incidents. To help us achieve zero incidents and no harm to the community, SMC is continuously adding new initiatives to our already established Safety Management System. These initiatives and programs better equip employees to identify, manage and minimize risks in the workplace in order to identify potential safety concerns before they emerge.

By incorporating safety initiatives on our site, we can help ensure the safety of our employees, the community and the environment

Working at SMC

At Shell Canada Products, we continue to build on our long history of quality products and we believe the people working at Shell operations across the country are crucial to that success.


Shell’s Corunna Refinery has 350 full-time employees. The number of contract workers on site varies according refinery’s schedule for turnarounds, construction and upgrades.

Property Line Monitoring (PLM) Program

Since registration to the Standard, an MOECC-approved Property Line Monitoring (PLM) program has been implemented through the installation of twelve ambient air monitoring stations along the perimeter of Sarnia Manufacturing Centre.

Data from the monitors will be collected in 14 day increments. This data will be compiled, analyzed, and posted to this website. A baseline concentration for each of the twelve stations will be established after three years, with each successive year of data being subject to analysis against the baseline.

The data collected from the PLM program will help SMC to continue to detect emissions and apply continuous improvement methods towards emission reduction.
