-
Socket Lake, north of Sioux Lookout
Residents and travelers are advised to check the Ontario Interactive Fire Map for real-time conditions in their area.
Drones and Fire Zones: A Dangerous Combination
Operating drones near wildland fires is both illegal and extremely hazardous. Drones can interfere with firefighting aircraft and endanger the lives of personnel working on the front lines. If you’re near a fire zone:
Be safe. Stay clear. Ground your drone.
