The investigation is underway to find out what may have caused a huge explosion that ripped apart a house on the 800 block of St. Claire Avenue this morning. One person was hurt and is in stable condition in hospital. Fire inspector Eric Nordlund says it's a scene like he has never witnessed before. Nordlund says there's windows and doors lying on neighbouring properties. Nordlund says the explosion was likely caused by what he calls a huge expansion of gas, but whether it was a natural gas blast, he couldn't say.
