Quebec's workplace safety board and the provincial police are investigating a fatal accident involving a smoking shelter that collapsed outside a factory in Granby, killing a man.

The Commission de la santé et de la sécurité du travail and the Sûreté du Québec are looking into the incident that killed the man at the Transformateur Delta plant on Industrial Blvd. on Thursday morning.

The victim and two co-workers were standing inside the small shelter on a morning cigarette break when it apparently collapsed under the weight of the snow that had piled up on the roof.

Two of the workers managed to free themselves, but their colleague, Eric Whitehouse, 34, was trapped against a table for 40 minutes and died of a heart attack.
 
Whitehouse was pronounced dead at the hospital Thursday afternoon.
