OTTAWA — The Ontario Fire Marshal's office has been called in to investigate after a Cumberland home worth $2.5 million burned to the ground early Tuesday morning. "It was a beautiful house. It's too bad," said Maria Tsourounakis, who lives next door. Fire crews responded to the call at 3304 Wilhaven Dr. at 4:24 am Tuesday.

He told fire crews he was awoken by the sound of an explosion in the garage. Ottawa Fire spokesman Marc Messier said when the man went outside to investigate, he discovered the garage was on fire. The man was uninjured, but he will not be able to return to his home and most, if not all, of the contents were destroyed, he said. Tsourounakis said she heard tires screeching in her driveway in the middle of the night. It was Proulx, who knocked on her door in a panic asking her to call 911, she said. Tsourounakis saw smoke billowing from the house and heard at least two more explosions, she said. She said Proulx didn't know what caused the fire, but told her he thought it might have been related to a boat charging in the garage. A recent real estate listing for the house describes it as "palatial living," with property taxes of $8000 a year.
