The US Department of Defense sent real-time satellite and sensor data to Canadian authorities to quickly identify new fires as the nation endures one of its most destructive early wildfire seasons.

He said the Biden Administration was also deploying additional US Department of the Interior (DOI), USDA Forest Service (USFS), and state wildland firefighting personnel and equipment to Canada.
