Dozens of firefighters were busy early this morning dousing a blaze at a home in the 100 block of Cathedral Avenue.

Crews were called to the home at about 2 a.m. after reports of a fire. A witness who called CBC News early Sunday morning said the fire was massive.

At least six fire trucks, an ambulance, a City of Winnipeg water tanker and other emergency vehicles were spotted at the scene around mid-morning.

Crews remained on the scene for hours in the morning and blocked off Cathedral to traffic. The section of road in front of the home was turned into a skating rink from all of the water used to douse the blaze that flooded onto the street and froze.

District platoon Chief Myles Fitzhenry said the three-storey home was a "total loss" after the fire, which was challenging to get under control due to the frigid temperatures.

"It is very [cold], makes firefighting efforts a little tougher working with the elements," he said. "Right now, we're changing crews every two hours. We have our rehab machine behind us that's heated with washroom facilities on it."

The building was occupied, but everyone got out safely, Fitzhenry added.

The cause of the fire, and the extent of the damage, isn't yet known.

No injuries were reported.

No more details are available at this time.
