Three people are dead and three in a hospital after being overcome by toxic fumes at a mushroom farm in Langley, British Columbia.
Const. Holly Marks of the Langley Royal Canadian Mounted Police says the incident happened on Friday afternoon when a group of workers entered a utility shed at Farmers Fresh Mushrooms Inc. Other workers who came to the men's aid also were overcome.
Two of those hospitalized are in critical condition; the third is stable.
Dozens of firefighters, emergency workers and a hazardous materials team were on the scene on Friday evening and RCMP say it appears the incident is not criminal.
B.C.'s workers' compensation board is investigating.
