But their efforts have been derailed yet again by recreational drones.
Parks Canada said they were forced to ground operations for over an hour twice in the past week.
It said flying drones during fire operations endangers the lives and well-being of pilots and firefighters both in the air and on the ground. In addition, when aircraft is grounded for any length of time, it causes unnecessary delays in firefighting efforts.
Since the wildfire broke out Sept. 1, four drone-related incidents have resulted in charges, which carry a maximum fine of $25,000.
