Coverage: Official active and new fire markers come from Ontario AFFES/LIO data. Marker data is informational and may not represent an exact perimeter. Local counts use the community centre and a 100 km radius; unavailable data never becomes zero.
These timestamps are intentionally separate: the responsible agency owns the source update, FireRadar records when it retrieved the data, and page generation does not replace either timestamp.

Wildfire context around Thunder Bay
Thunder Bay is a major service centre for northwestern Ontario, where wildfire incidents may occur across large and remote areas. Official AFFES records are shown separately from thermal detections and mapped perimeters.
How to read local distance results
Distances are calculated from the centre of the selected location to the point supplied for each record. The local activity list is limited to 100 km. A fire can be large, irregularly shaped, remote, or represented by a reference point rather than an exact perimeter.
