On Feb. 13, Colton Quast, a 25-year-old worker employed by A Circuit Electric Ltd., suffered electric shock-related injuries at the worksite of the future Amazon warehouse south of Edmonton.

Emergency crews were called to Nisku Spine Road and 41 Avenue south at around 12:30 pm that day. Quast was taken to hospital in critical, life-threatening condition and was put into a medically-induced coma. He passed away on Wednesday, according to a Facebook post by his mother, Marlyn Quast-Frank, reports CTV News.

Occupational Health and Safety is investigating the incident, and “has issued a stop use order to prime contractor Dawson Wallace Construction Ltd. for the electrical cabinet involved in the incident,” a government spokesperson confirmed to CTV News. “The order stays in place until the cabinet is examined by an engineer and deemed to be in safe operating condition.”

According to CTV, no other orders have been issued at this time. The warehouse is not currently operational or under Amazon’s control yet.
