A family of four escaped uninjured after their house in North York caught fire in the early hours of the morning.

Toronto Fire Services were called to the detached house on Marmion Avenue near Barse Street just before 2 a.m. and started fighting the fire from the inside before realizing the extent of the blaze. 

"Then they discovered the entire second floor was fully involved in fire, so they went into defensive mode, which means they continued attacking the fire from the outside," said Toronto Fire Services Captain Michael Westwood. 

Platoon Chief Kaarel Betlem, who was on the scene, said the fire appeared to start in the garage and then spread to the second floor.

Two cars parked in a double garage, including at least one Porsche, were completely engulfed in flames as well, making loud popping sounds as tires and batteries blew out. 

The family was able to escape, said Betlem, because the father had not yet gone to sleep and saw the flames, waking his wife and their two children. 

By 2:42 a.m., the fire had been successfully put out. No surrounding homes were evacuated in the process. 

So far, there's no theory as to what caused the fire. 

"We're holding the scene for a Toronto Fire Services fire investigator to attend in the morning," said Westwood. "A fire crew will remain on the scene just in case anything flares up."
