Imperial Oil reported temporarily elevated flaring at its Sarnia refinery on Monday after a change in operating conditions, the company said in a brief notification to market subscribers.
What was reported
The company’s Sarnia facility, which has a crude-processing capacity of 113,000 barrels per day (bpd), experienced increased visible flaring during a period of adjusted operations. Imperial described the event as temporary and linked it specifically to a change in operating conditions at the plant.
Details released to the market were limited, and the initial notice did not include information on the duration of the elevated flaring or whether there were any impacts to nearby communities.
Local context and recent refinery activity
Sarnia is home to multiple petroleum refining operations, and the city has seen operational disruptions at more than one facility in recent weeks. In related industry reports, Shell and Suncor were also noted to have experienced problems at their Sarnia refineries over the preceding weekend, including incidents involving a loss of power.

Why elevated flaring matters to residents
Flaring is used across the oil and refining sector to burn off excess hydrocarbons during upset conditions or equipment changes. While refineries and regulators say flaring can be a necessary safety measure, elevated flaring can produce visible flames and increased emissions, drawing attention from neighbours and municipal authorities.
For Sarnia residents, even temporary increases in flaring can prompt concerns about air quality, odours and potential impacts on health and local environment. Municipal and provincial bodies monitor refinery operations and emissions, and industry notices like the one from Imperial typically prompt follow-up questions from local officials and community groups.

Next steps and what to expect
Imperial’s initial notice did not provide a timeline for returning to normal flaring levels or further technical detail. Residents and local stakeholders typically look to the company, the province and municipal emergency or environmental services for follow-up statements and any monitoring results.
Given the recent cluster of operational notices from refineries in Sarnia, local officials and community groups are likely to continue seeking clarity about causes and any measures being taken to minimise recurring incidents.
WE NEWS will seek additional comment from Imperial Oil and local authorities and will report any new information about the incident, including timelines for return to normal operations and any monitoring data made public.
