The Brunswick Creek wildfire near Boston Bar, British Columbia, continues to burn out of control, prompting the closure of Highway 1 as officials warn the blaze is expected to grow. The fire, which ignited in the steep canyon terrain, has forced emergency crews to shut down the major transportation artery indefinitely.
Highway 1 Closure and Evacuations
The British Columbia Ministry of Transportation announced the closure of Highway 1 in both directions through the Fraser Canyon, citing extreme fire behaviour and safety risks for motorists and first responders. The closure stretches from the junction with Highway 7 to the Boston Bar area, with no estimated time for reopening. Traffic is being diverted via Highway 3 and Highway 5, adding significant travel time for commuters and commercial vehicles.
Evacuation alerts have been issued for properties near the fire, and the BC Wildfire Service has deployed additional crews and air support to combat the flames. According to the service, the fire has grown to an estimated 200 hectares as of July 7, 2026, and is expected to expand further due to dry conditions and gusty winds.
Fire Behaviour and Response
The Brunswick Creek fire is classified as a Rank 3-4 fire, exhibiting intermittent crown fire behaviour with moderate to high rates of spread. Firefighters are working to establish containment lines, but steep terrain and limited access are hampering ground operations. Air tankers and helicopters have been conducting water and retardant drops to slow the advance.
“The fire is in a very challenging location, with steep slopes and heavy fuels,” said a BC Wildfire Service spokesperson. “We are expecting growth over the next few days as temperatures remain high and winds pick up.” The fire is believed to have been human-caused, and an investigation is underway.
Impact on Communities and Travel
The closure of Highway 1 has stranded some travellers and disrupted supply chains. Local businesses in Boston Bar and surrounding areas report reduced customer traffic. The Village of Boston Bar has set up an emergency reception centre at the community hall for those affected by the evacuation alert.
“We are closely monitoring the situation and urging residents to be prepared to leave at a moment’s notice,” said a local emergency official. “Safety is our top priority.” The Ministry of Transportation advises drivers to check DriveBC for updates and avoid non-essential travel through the region.
Wildfire Season Context
The Brunswick Creek fire is one of several active wildfires in British Columbia this summer. The province has experienced above-average temperatures and below-normal precipitation, creating tinder-dry conditions. The BC Wildfire Service has recorded over 300 wildfires so far this season, with several burning out of control.
Environment Canada has issued heat warnings for parts of the Interior, with temperatures expected to reach the high 30s Celsius. The combination of heat, low humidity, and unstable air masses increases the risk of thunderstorms and lightning, which can spark new fires.
