A man and woman are in hospital with serious burns after fire ripped through their home in St. Hubert early Monday morning.

The fire started on the first floor of the home at 1884 Place Mauriat and rapidly spread upstairs at around 1:00 a.m.

The rapidly-encroaching flames caused the woman leap out of A second-storey window onto a patio table in her backyard. She was cut and suffered burns to her face and hair.

"I wouldn't wish that on anybody," said neighbour Fatiha El Bahairi, who expressed shock while recounting to CTV Montreal what she had witnessed.

The man was rescued by firefighters but only after suffering second and third degree burns to 20 percent of his body, leading authorities to transfer him to the Hotel Dieu Hospital in Montreal from a hospital on the South Shore.

He was described as being in critical condition but was later upgraded to stable.

It is believed that the fire spread from after someone failed to extinguish a butt after smoking inside the home.

The home did not have a working smoke detector with functioning batteries.
