The BC Coroners Service has called an inquest into the April 19, 2010 death of Colette Marie Salemink.
Salemink's son, Blake, was charged with arson and manslaughter but was found not criminally responsible by reason of a mental disorder this past May.
Coroners' juries may not make any findings of legal responsibility.
But they can make recommendations to prevent deaths under similar circumstances in the future.
The inquest will take place from Nov. 13 to Nov. 16 in Burnaby, B.C.
According to media reports, Colette had called mental health officials to get help for Blake just days before the blaze and Blake's arrested in Oregon.
