The building site remains an active emergency scene withfederal, provincial and military investigations all beginning Friday but extensive damage to the building has made clearing it a challenge.

He offered his gratitude to all personnel who responded to the scene Thursday morning.

Capt. Brad Little was working in his office across the street from the barracks building when the blast happenedand it was strong enough to cave in part of the office building's ceiling.
