Fires near Guelph right now
NASA's VIIRS sensors detected 48 thermal hotspots in 5 separate clusters within 80 km of Guelph, Ontario, Canada in the last 48 h. The closest is 36 km SE of the city centre (8 km N of Ancaster), with 4 detections and a peak fire radiative power of 2 MW, which is low-intensity for a single 375 m pixel.
None of the clusters is within 25 km of the centre, so the city itself is not in the immediate fire area, but smoke can travel hundreds of kilometres.
The largest nearby cluster by detections is 47 km SE (4 km ENE of Hamilton) with 37 detections; first seen Sat 2 am and last seen Sun 1 pm local time.
Across Canada there are 110 fire clusters in the same window, 24 of them in Ontario.

Smoke and wind
Current wind data was unavailable for this page; smoke generally drifts with the wind, so check local conditions.
Smoke shows up first as PM2.5 on air-quality monitors; the Guelph air quality page has the live reading.
Evacuations and official information
GodsView shows satellite detections only. It does not know fire perimeters, containment or evacuation zones. Always follow evacuation orders from local authorities.
CIFFC (ciffc.net) publishes the national wildfire situation; provincial fire status and evacuation alerts come from Ontario Forest Fires (ontario.ca/page/forest-fires). Alertable and local emergency alerts carry evacuation orders.
About satellite fire detections
Satellite thermal hotspots are not all wildfires: gas flares, steel works, volcanoes and planned agricultural or prescribed burns show up too. VIIRS passes over most places about twice a day, so a fire can start or grow between passes, and thick smoke or cloud can hide one.
Fire radiative power (FRP) is the heat a fire gives off, in megawatts per pixel: under 10 MW is usually a small or smouldering fire, over 100 MW an intense flaming front.
