Chilliwack barn previously used as a marijuana grow-op goes up in smoke

A large barn on Chadsey Road in Chilliwack, B.C. had smoke pouring out from all four sides Monday morning, after a fire started at around 8:30 a.m. PT.

The barn had previously been used as a licensed marijuana grow-op, said Chilliwack RCMP.

Police couldn't confirm what the ban contained at the time of the fire, but they've contacted Health Canada to check.

It's not clear what started the fire. No one was hurt, according to police.

The owners of the barn are cooperating with police.
