Debate grows over human role in New Brunswick wildfire causes

Government urged to identify wildfire causes

New Brunswick’s former public safety minister has called for greater transparency on the causes of more than 400 wildfires recorded across the province this year.

Canadian Underwriter reported that Kris Austin, a Progressive Conservative MLA and former cabinet minister, raised the issue during a standing committee on public accounts meeting on Wednesday.

Austin said he believed many of the fires were caused by people and urged the government to investigate and release more information.

He said: “How are these fires starting? It seems to be a big question mark. I get the impression government is a little hesitant to push on that.

“And that’s something I’d like to see more information on. How are these fires starting? We know anecdotally, at least, that a lot of them seem to be human-induced.”

He cited national data indicating that in most regions outside New Brunswick, human activity is responsible for more than half of all wildfires.

Provincial authorities have stated their priority has been firefighting operations, not identifying causes.

Officials have not linked any of this season’s wildfires to arson or other deliberate acts.

Officials continue wildfire investigations

According to the Department of Natural Resources, several fires in the province’s northeast during August were triggered by dry lightning.

Other incidents remain under investigation, including the Irishtown wildfire near Moncton, which prompted evacuation standby orders for 1,500 residents in early August.

Deputy Minister Cade Libby told Austin that the Irishtown investigation was still ongoing.

Libby said: “I don’t want to speculate at this point, other than we are completing an investigation of the start of that fire, and we’ll see what the conclusion is after that.”

Austin said reporters should continue to question government departments about the findings but declined to elaborate on his own view.

During the total fire ban imposed between August and September, 43 people were fined for violations including illegal campfires.

One forestry operation received the largest fine for failing to have required firefighting equipment.

The total value of penalties exceeded $2,000.

Rising wildfire numbers exceed long-term averages

Deputy Minister Libby said the wildfire season could extend beyond its typical end date of 31 October due to ongoing dry conditions.

He said: “This is probably one of the worst years we’ve had. Could we see more starts or ignitions? Yes, we could, especially if we don’t get the rain. Today’s rain is helping, but we do need more of it.”

As of Wednesday, 421 wildfires had burned more than 3,500 hectares across New Brunswick.

This figure is well above the 25-year average of 240 fires and 312 hectares burned annually.

No lives or homes were lost, though several firefighters were hospitalised for heat exhaustion and power infrastructure near Miramichi was damaged.

Authorities lifted a province-wide fire ban this week following rainfall but warned it could return if dry weather resumes.

Relevance for fire and safety professionals

The investigation into wildfire causes in New Brunswick holds relevance for public safety authorities, emergency management planners and wildfire response coordinators.

Determining the proportion of fires caused by human activity compared with natural events could influence future prevention campaigns, enforcement priorities and seasonal fire restrictions.

Extended wildfire seasons and higher ignition rates also have implications for resource planning, firefighter fatigue management and equipment availability across regional agencies.

Accurate cause data would enable more targeted education for residents and industries operating in high-risk areas such as forestry and recreation.
