Investigators are probing an early morning house fire in North York that injured five people, including three firefighters.

The fire broke out at approximately 1:30 a.m. Thursday morning, in a house on Gordon Road in the Bayview Avenue and York Mills Road area, trapping a 65-year-old woman in an upstairs bedroom.

"We had a report of a woman trapped. We started (an) immediate rescue protocol," District Chief Kaarel Betlem with Toronto Fire Services told CP24.

Betlem said three firefighters searching for the woman also became trapped and had to be rescued.

"It was a three-man crew trapped within the house, and within a few minutes they were rescued inside," Betlem said at the scene. "They went to the hospital and now they are back at their station."

The woman and her husband, who police say was found on the front lawn of the residence suffering severe burns to his upper body, were both taken to hospital.
