A one-year-old girl injured in a fire pit incident near Port Burwell, Ont. on Monday has died, a relative has confirmed.

Jake and Tina Hiebert and three of their children suffered burns when the family gathered for a bonfire at a home on Vienna Line and were being treated in hospital.

A relative says a jerry can with diesel fuel exploded, seriously injuring the couple, as well as leaving a seven-year-old girl, four-year-old boy and one-year-old girl with life-threatening injuries. Two other children were not injured.

The youngest girl has now died in a Toronto hospital, a relative has confirmed.

One-year-old Layla reportedly died Thursday morning.

Bayham Fire Chief Harry Baranik, who was first on scene, has described the scene as 'traumatic,' saying there was a sense of 'helplessness' as they tried to aid the children.

The Ontario Fire Marshal's Office continues to investigate.

So far more than $40,000 has been raised to support the family though a GoFundMe page.
