A raging fire that tore through a Dartmouth, N.S., apartment building Saturday has left more than 70 people displaced, with many losing all their homes and belongings.

While many residents of the 64-unit building at 25 Arthur Street are homeless because of the fire, others have lost belongings and their apartments due to extensive smoke and water damage.

Resident Anne Connolly said she is shocked by the events.

"We just lost our sister, she just passed away. Then the building burns. I'll think about it later," Connolly said.

The fire burned through most of the day — at one point causing part of the four-storey building to collapse and the walls to crumble onto a nearby firefighter.

Halifax Regional Municipality said that every available fire unit fought the blaze.

Red Cross disaster response personnel on the scene said 35 tenants have registered for emergency assistance. Most tenants have found temporary places to stay with family or friends, the Red Cross said in a news release.

The building was evacuated after the fire began in the morning.

There are no reports of injuries.

Some pets died in the fire.
