This is an eyewitness report from the NowPublic member aletteke who was on the scene.
Explosion and Fire at Nanaimo and Dundas in Vancouver
Involved is a three story strata building on the north side of Dundas street. We were rocked by the force of the explosion two blocks away. All emergency vehicles responded very quickly and the cleanup is continuing as I write this. I will post more pictures as I do a walk by. Cause is speculative, but from the force I would not discount a meth lab. from where I am at least three units are now unlivable, probably more.
I took my German Shepherd for a walk, man may have left common sense, but I have him, just in case it was too toxic I figured he was good to take with. Walking up the the damaged bulding along Garden Street were clothes which had been cut off the injured two recognizeably from a small size female others in a small pile. Many bottles of distilled water strewn accross the sidewalk. Firemen were still working the scene and ambulances were still standing by. I took several shots accross the alley from the damage behind another building. Glass was everywhere. several neighbouring buildings had windows broken. People were standing ourside their buildings visibly shaken from the concussion. The phrase someone was cooking was something I overheard over and over. It is hard to think what else on a warm day could have produced such a blast and fire. Makes you wonder if you shouldn't know your own neigbours a bit better.
