Minimal information was reported as to how and why a school bus caught fire on Innis Lake Road in Caledon East, north of Toronto, Ontario, on March 12, 2026. It was reported that 44 high school students and the bus driver were able to escape without injury. An article posted by CTV News in Barrie stated “Officials confirm the fire is not considered suspicious and appears to have been mechanical in nature” but that can mean many things.
“Not considered suspicous?”, what does that mean? Is it not relevant because someone believes the bus was not set on fire on purpose? Is that why officials recommend that we “move on, nothing to see here”? Does it matter whether the bus was set on fire on purpose or accidentally? Would either cause the potential of multiple deaths? Clearly there is a reason why we ought to know how and why the bus caught fire. Did the fire originate from a hot exhaust system? Did it originate from a wiring problem? Specifics are needed.
Nothing has been said about which bus operator owned the bus or who manufactured the bus. We can examine some the general characteristics of the bus in the above photo and we can come to some general conclusions.
The bus does not appear to be of an older vintage. As buses get older they begin to show warning signs that become displayed on the dash. Some of these warnings occur because certain sensors become aged and less functional. So something like a wheel sensor warning indicating a traction control issue may be of minimal concern. On older buses the engines do not work like they used to and we often see a “hot exhaust” warning and this may be a continual display on the bus without a simple remedy. But this is not a common problem on newer buses.
Diesel buses need Diesel Exhaust Fluid (DEF) to keep the engine from getting clogged up and when this fluid is not topped up we can get overheating of the engine and exhaust. So it would be important to determine what was the status of the DEF before this bus caught fire.
In 2025 Gorski Consulting posted articles on July 28 and September 16, regarding electric school buses manufactured by Lion Electric Company of Quebec. Those buses were taken off the road after a Lion bus caught fire in Montreal in early September, 2025. So it would be helpful to determine whether the bus fire at Caledon was a Lion bus. However, no one has provided that important information.
Although there are several types of buses driven on roads in southern Ontario, a large number come from just a few manufacturers. Below is a photo taken of the rear of a Lion bus and if we compare its features to the photo of the burning bus at the beginning of this article it does not resemble a Lion bus.
The next photo below shows the rear end of an International bus and it too does not appear to match the features of the burning bus.
In the next photo we see the rear of a Thomas built bus and its features seem to be similar to those of the burning bus.
Thomas buses are built in North Carolina.
All persons involved in school bus transportation ought to be viewing this school bus fire with concern. As mentioned on this Gorski Consulting website so often, secrecy is of no help to anyone expect to those who have a vested interest in hiding something for which they should be accountable. All persons should be voicing their right to know how and why this bus caught fire.
