The police say the bombing happened Aug. 11, but wasn't reported for a day because residents initially believed the blast was a lightning strike.
A resident came to the local RCMP detachment with a piece of shrapnel, prompting officers to attend the scene and determine a homemade bomb was detonated under a parked car.
No one was injured in the blast, but a large piece of metal was found inside a garage after ripping through a wood stud.
Police say 23-year-old Eric Daoust and his 19-year-old brother, Stephen, have been charged with using explosives.
RCMP Cpl. Dan Moskaluk says it appears a young man who lived in the home was targeted by two people with whom he had a long-standing conflict.
