The fire was discovered on the afternoon of July 20, at the northern edge of the Woodfibre LNG site.
It grew to 0.20 of a hectare at one point.
Company spokesperson Rebecca Scott said that as soon as the fire was discovered, two employees and a BC Marine Logistics staff member, returned immediately to the site to assist BC Wildfire Service firefighters.
BC Wildfire Services have remained on-site since the fire was reported and have now declared that the fire is out, Scott said.
"Woodfibre LNG is deeply grateful for the rapid response and hard work of the BC Wildfire Service's crew during a very challenging fire season," Scott wrote in a news release sent out Sunday evening.
"We’d also like to sincerely thank our team members and the BC Marine Logistics team who have gone above and beyond to support the activities on site."
No known cause is listed for this fire.
The other Squamish-area fire — the Upper Pitt River fire discovered on July 22 — has also been declared out by the BC Wildfire Service.
At one point, it reached 0.60 of a hectare.
It was human-caused, according to the BC Wildfire Service.
