Parkland expects it will take about four weeks for the refinery to return to normal operations, and plans to increase refined fuel imports into its on-site shipping terminal to fulfill deliveries to customers in the meantime.

Parkland paused some operations at the refinery last week during a blast of extreme cold weather that swept across western Canada and ran into problems during the restart.

"While restarting, we encountered an issue with a processing unit on January 21, 2024. As a result, we paused the restart and the refinery's processing operations remain temporarily shut down," said Alex Coles, vice president and general manager of the refinery, in a statement.

Over the weekend local media reported a strong burning smell across the Vancouver area that was attributed to the refinery, and Parkland spokesperson Simon Scott confirmed the odor was a result of the operational issues.

RBC Capital Markets analyst Luke Davis said the shut down would likely have a C$25 million-C$35 million ($25.88 million) impact on Parkland's first quarter earnings before interest, tax, depreciation and amortization.
