Cenovus Energy reported a workplace death at its Christina Lake oilsands site in northeastern Alberta on Wednesday.

According to the Calgary-based company, an employee of a company Cenovus contracts was killed on site, about 350 kilometres northeast of Edmonton, in an incident at about 10:20 p.m. Tuesday night involving a hauling truck and a drilling rig.

In a tweet sent out on Wednesday morning, the company said it is "deeply saddened to report a worker fatality has occurred at our Christina Lake oil sands site in Alberta," and extends its "deepest sympathies to the worker's family, friends and co-workers."

The worker's name has not yet been released.

Cenovus reports it has, "notified the appropriate authorities and is conducting a full investigation into the cause of the incident."

The Christina Lake site opened in 2000. Bitumen there is deeply buried and pumped to the surface via steam-assisted gravity drainage.

The site has been undergoing expansion since 2017, as the company adds 50,000 barrels per day to its operations.
