Peat turned himself into Langley RCMP on Thursday after he was charged with arson with disregard for human life and arson causing property damage.
RCMP say the fire broke out at a home on the 4400 block of 208A street on March 17 just before 11 p.m. PT.
At the time Cpl Holly Marks said police had determined there was a dispute at the home between a father and a son earlier in the day.
Later that evening after the father had gone to bed, a passerby spotted someone attempting to start a fire outside the home.
"A passer-by witnessed the arsonist as he was lighting the fire and made attempts to thwart his efforts, however the house fire was reported a short time later," said a statement released by RCMP last week.
Peat appeared in court to face the charges on Monday.
He played in five hockey leagues over his career, including off and on for the NHL's Washington Capitals from 2001 to 2006.
