The announcement was made during a meeting of the Stormont Assembly Health Committee on Thursday.
Addressing the committee, Dr Kieran Deeney, a west Tyrone MLA and GP in Omagh, said the case was the worst he had ever encountered in his time as a GP.
Dr Deeney warned against a "witch-hunt" but maintained lessons needed to be learned so that a similar tragedy can never be allowed to happen again.
"We've got to act and make sure this never happens again," he said.
"All of the agencies which were involved with the McElhill-McGovern family want to learn the lessons from the events surrounding the fire and clearly the Toner report points out quite a number of important issues," Glenn Houston from the Quality Improvement Authority also told the committee.
Convicted sex offender Arthur McElhill killed himself, his partner Lorraine McGovern and their five children when he torched their Lammy Crescent home in November 2007.
In 2008, an independent review of the handling of the family's case by social workers and other statutory agencies flagged up a catalogue of mistakes and oversights.
The review carried out by Henry Toner QC revealed that less than a month before the tragedy the family's eldest child - 13-year-old Caroline - called the police to report a raging argument between her parents.
But while officers investigated, no one interviewed the schoolgirl herself. And though the police then passed the file to the local health trust, no social care follow-up visit was undertaken.
Caroline again dialled 999 on the night of the fire, but by then it was too late. When her body was found inside the gutted house the phone was still clasped in her hand.
The Toner review also found that only weeks before the fire, the family's case, which had been classed as an "orange" priority after concerns were raised about the risk Mr McElhill posed to his children, was downgraded to "green".
The inquiry noted that not all agencies were aware that Mr McElhill, who fathered Caroline with Ms McGovern when she was just 15, had twice been found guilty of indecently assaulting 17-year-old girls in the 1990s, resulting in his imprisonment in 1998.
