Winnipeg Fire Paramedic Service crews were called to battle a 'significant fire' in a warehouse at 274 Jarvis Avenue Monday.

Fire crews and police responded to an automatic alarm just before 12:45 a.m. and found a well-involved fire.

It spread across the building which occupies a full city block, the fire service said. Most of the building had collapsed.

Manitoba Hydro cut power to the surrounding area to make sure hydro lines, power, and transformers don’t add to the hazards.

“We’ve cut the power along the lines here on the north side because what’s left of the building behind me is in danger of imminent collapse and could well take down the hydro lines as well,” Winnipeg Fire Paramedic Service chief John Lane said.

The city also tweeted that smoke from the fire is travelling east across the city and people are being asked to close their windows.

CTV News observed multiple fire crews, including an aerial truck fighting the fire.

At one point, crews were dispatched to fight a fire on the roof of another building caused by a flaming ember.

“One of them (flaming embers) landed on roof of a building to the east of this building, but we noticed it and attacked it right away and were able to extinguish the fire with minimal damage to the roof.”

WFPS said one firefighter suffered a slip and fall injury, but was able to continue working.

CTV News also saw people from the Salvation Army Community Response Unit passing drinks and snacks to people affected by the fire.

Debbie Clarke, the emergency disaster services director for Manitoba and northwest Ontario was there.

“We’ve done a lot of coffees, hot chocolate, and snacks, just giving everybody some hydration, some bottles of water. A few snacks to keep up the energy and I gave out a couple of blankets to a couple of the evacuees,” she said.

The cause of the fire is under investigation and no damage estimates are available at this time.

Lane said fire crews will likely be on scene for 48 more hours to tear down the rest of the building and extinguish hot spots.
