Evacuation and Implementation Information

Residents and travellers should continue to monitor current Evacuation Orders, Implementation Orders and Evacuation Alerts before entering areas affected by wildfire operations.

Conditions can change quickly, and local restrictions may remain in place even when broader regional restrictions have been lifted.

NOTAM Remains in Effect Around Thunder Bay 36

A Notice to Airmen, or NOTAM, remains in effect in the area of Thunder Bay 36.

The restriction is in addition to standard airspace rules under section 601.15 of the Canadian Aviation Regulations.

Airspace around active forest fires is restricted to wildfire suppression aircraft within five nautical miles of the fire and up to 3,000 feet above ground level.

Pilots are reminded to check NAV CANADA’s flight-planning information for current wildfire NOTAMs before flying.

Fort Frances 14 Airspace Restriction Continues

A separate NOTAM remains in effect in the area of Fort Frances 14, northeast of Byers Lake.

Unauthorized aircraft can interfere with helicopters, waterbombers and other firefighting operations.

Pilots should confirm all current restrictions before entering wildfire areas.

Wildland Fire Hazard Continues to Vary Across the Northwest

Ontario’s interactive fire map provides current wildland fire danger ratings based on data from more than 130 weather stations across the province’s fire regions.

The map changes throughout the day as weather conditions are updated.

Residents, campers, anglers, hunters and travellers are encouraged to check the current fire hazard before heading into forested or remote areas.

Outdoor Burning Rules Remain in Effect

Ontario’s legislated forest fire season runs from April 1 to Oct. 31.

Aviation, Forest Fire and Emergency Services is reminding the public that outdoor burning rules remain in effect.

Where outdoor burning is permitted, fires must be started no earlier than two hours before sunset and extinguished no later than two hours after sunrise.

Anyone burning outdoors should have adequate tools and water available to control and extinguish the fire.

Residents within municipal boundaries should also check with their local fire department for any burning restrictions or permit requirements.

How to Report a Wildland Fire

To report a wildland fire north of the French and Mattawa rivers, call 310-FIRE (3473).

To report a wildland fire south of the French or Mattawa rivers, call 911.

Although overall fire behaviour has eased in several major complexes, a number of large fires remain not under control and suppression work continues across Northwestern Ontario.
