Approximately 50 firefighters were called to the scene of a house fire in the west-end of Toronto Friday afternoon.

Toronto Fire received a call that two garages, a car and a semi-detached home were on fire at 12:44 p.m., near Dundas Street West and Jane Street.

It started in the garage at 9 Sun Valley Dr., extended to the house then spread to the adjoining home on the left, and to the roof of a detached house on the right, firefighters said.

"Within a few minutes, it was fully enveloped. The whole garage went up. You could see that it was spreading to the house," Mike Wright, a witness who captured the fire on his smartphone, told CTV Toronto.

The fire likely jumped from the townhouse to the neighbouring detached home due to wind, Toronto Fire Commander Bob O'Hallarn said.

The interiors of two of the homes were completely destroyed, and the roof of another was damaged, O'Hallarn said.

"It escalated very quickly to a second alarm and then we went to a third," O'Hallarn told media at the scene, adding that 13 trucks were used to get the fire under control.

No injuries have been reported, and there were no occupants inside the homes at the time of the fire.

The Ontario Fire Marshal has been notified, as the damage is estimated in excess of $500,000.
