Durham Regional Police have arrested a man following a home explosion that injured three people in Whitby Wednesday afternoon.

The explosion, police say, happened as butane was being used in the production of cannabis oil.

When emergency services arrived around 3:30 p.m., they found “obvious signs of damage,” according to a Thursday press release.

Fire crews discovered three men inside the home who were all transported to hospital with non-life-threatening injuries.

“There was no fire after the explosion but there is structural damage,” Whitby Deputy Fire Chief Mariano Perini said of the multi-unit dwelling, located near the intersection of Garden and Dundas streets.

Photographs taken Thursday morning show a wall that appears to have been partially blown off the house by the blast.

Jody Cormier, 48, of Whitby, is charged with criminal negligence, arson with disregard for human life and altering cannabis with an organic solvent.
