An Ottawa man charged with first-degree murder in the death of his mother last year has been referred to the Ontario Review Board after he was declared mentally unfit to stand trial for a second time.

René Goudreau was charged after his mother, 53-year-old Lucie Goudreau, was found dead after a fire in her main-floor apartment at 90 Woodridge Cres. on Nov. 27.

Goudreau underwent a psychiatric assessment at the Royal Ottawa Mental Health Centre soon after he was charged. The psychiatrist decided Goudreau doesn't understand the charge against him, doesn't understand the court process and is unable to give his lawyer, Douglas Baum, guidance on how to proceed with the case.

The court ordered another 60-day psychiatric assessment on Jan. 11 and again he was deemed unfit to stand trial Monday.

The Ontario Review Board will determine whether to discharge Goudreau, offer a conditional discharge or order him to be detained in a hospital.

An absolute discharge would only be granted if it deems "the accused is not a significant threat to the safety of the public."
