Evacuation alert for Jasper, Alta., lifted as wildfire in national park now being held: officials

The evacuation alert for Jasper, Alta., was lifted on Saturday, after a large fire in the national park was classified as being held, officials said.

The Jasper Wildfire Complex, a group of fires that have burned more than 33,000 hectares combined, was burning out of control for nearly four weeks. One of its fires destroyed one-third of the historic townsite, before merging with another in the group.

Firefighters progressively gained on its perimeter, and on Saturday, Parks Canada and Municipality of Jasper officials announced the flames were contained.

"Today, all the dedication, teamwork and sacrifice has paid off," Jonathan Large, an incident commander for Parks Canada, the agency leading the wildfire response, said during a virtual news conference.

A wildfire is classified as being held once it's completely contained, according to an Alberta Wildfire document. Fires with this label are not expected to move beyond the established boundaries under prevailing or forecasted weather. The fire may still be active and emit smoke, but it is considered contained.

Sometimes, extreme weather could push a fire out of control again, the document says. But usually, once the flames are held, firefighters can reinforce their containment lines and start working to get control over the fire.

"With the forecast we have, the work done and the amount of crews and helicopters and such, we don't expect that fire to spread," Large said. "We're on track to get [to an under-control phase] in the coming weeks."

As a result, the evacuation alert for the town of Jasper — not the entire national park — has been lifted, Municipality of Jasper incident commander Christine Nadon later told CBC News.

"That's very big news for people of the townsite," Nadon said.

The Jasper Wildfire complex is among 104 total wildfires burning throughout Alberta as of 11:45 a.m. MT Saturday, according to the Alberta Wildfire dashboard.

Lightning sparked several fires in the national park in mid-to-late July. Two of those fires — one north, another south of Jasper — started threatening the town and the highways that access it.

On July 22, the Alberta Emergency Management Agency issued an evacuation order for the national park. An estimated 25,000 people, including the roughly 5,000 residents of Jasper, had to flee late that night.

Before 7 p.m. MT on July 24, the south fire was burning in the town. The flames, officials have said, reached more than 100 metres high and forced many first responders to relocate to Hinton, Alta.

The fire destroyed 358 of the 1,113 total structures in Jasper. Most of those homes and businesses were in the west end.
