An unprecedented string of wildfires in Canada’s Atlantic coast province of Nova Scotia continued to burn out of control for a fourth day on Wednesday, prompted the evacuation of 18,000 people.

Fire officials were hoping for a break in the dry, windy weather, but that’s not forecast to happen until Friday night at the earliest.

Firefighters worked through the night to extinguish hotspots in a fire that started in the Halifax area on Sunday, deputy fire chief David Meldrum said.

He said it was too early to give an exact count of homes destroyed, but the municipal government put the toll at about 200 buildings.

Mr Meldrum made it clear that none of the 16,000 evacuees from the suburbs around Halifax will be able to return home for now. Another 2,000 people who fled a much larger uncontained fire in southwestern Nova Scotia also are being kept away from their properties.

Nova Scotia Premier Tim Houston announced the province would be banning all travel and activity in all wooded areas as of 4pm local time (8pm BST).

The ban applies to all forestry, mining, hunting, fishing, hiking, camping, off-road vehicle driving and all commercial activity on government lands.

“We’re in a very serious situation in this province, and we need to take the steps that we can to protect Nova Scotia,” Mr Houston told a news conference via a video call from Shelburne, Nova Scotia, where the province’s largest wildfire has been burning since the weekend.

“I wanted to get a sense of the damage here. It’s extensive. It’s heart-breaking.”

Dan Cavanaugh was among two dozen people waiting Tuesday in a Halifax-area parking lot to learn if their suburban homes had been consumed by the wildfire.

“We’re like everyone else in this lot,” said the 48-year-old insurance adjuster. “We’re not sure if we have a house to go back to or the extent of the damages.”

Police officers were writing down the names of residents and calling people to be escorted to see what had become of their properties.

Sarah Lyon of the Nova Scotia Society for the Prevention of Cruelty to Animals said an eight-member team was preparing to head out into the evacuation zone to retrieve animals left behind.

In all, about 16,000 people have been ordered to leave their homes north-west of Halifax, most of which are within a 30-minute drive of the port city.

The area under mandatory evacuation orders covers about 38 miles.

Sonya Higgins said she and more than 40 others waited in a nearby supermarket parking lot to be led into the evacuation area, in hopes of retrieving seven cats from two homes.

Ms Higgins runs a cat rescue operation in Halifax, and she says the pet owners contacting her are “frantic” to find their animals and get them to a safe place.

Earlier in the day, fire officials said that with the return of dry, windy conditions on Tuesday, there could be a “reburn” in the evacuated subdivisions.

The extended forecast predicted hotter weather on Wednesday and no rain until Friday at the earliest.
