Dave Meldrum, a spokesman for Halifax Regional Fire and Emergency, said a steady rainfall helped ground crews douse smouldering spots near Williams Lake in Spryfield.
An evacuation order that was put in place shortly after the fire erupted Monday was lifted.
Meldrum said crews from the fire department and the provincial Natural Resources Department were likely to remain in the area for a few hours as a precaution.
"They've got really positive results," said Meldrum.
He said it was still too early in the investigation to say what caused the fire.
The fire broke out in a wooded area around 4:15 p.m. Monday, leaving plumes of smoke that could be seen kilometres away. Two helicopters were dispatched to drop water in the area.
The blaze follows a fire three years ago in a nearby area of the city that forced the evacuation of 1,100 people and razed eight homes.
