WINDSOR, ON—A 33-year-old man who was employed by a vendor at the Stellantis assembly plant here is facing multiple charges in connection with an explosion at the plant earlier this month.

James Harris was arrested Nov. 17 at his home in Windsor. Police later searched the home with a remote-controlled robot.

Harris faces charges that include explosion with disregard for human life and intending to cause an explosion likely to cause harm or death or serious damage to property, police said.

Police did not say what might have motivated the suspect, but Canadian media and a union official suggested he was angry about the COVID-19 vaccine. Stellantis has announced a vaccine mandate for its autoworkers in Canada.

”We want to thank the Windsor Police Department and the entire task force for their swift response in investigating this incident and helping to ensure the safety of our workforce. We remain grateful that no one was harmed as a result of this deliberate action,” according to the statement provided by spokeswoman LouAnn Gosselin.

No one was hurt in the explosion, which occurred in a storage area at the plant the evening of Nov. 4.
