The Toronto Fire Services later said crews remained on the scene after a two-alarm fire on the roof of a commercial building on Richmond Street West led to ruptured propane cylinders, heavy flames, and thick smoke. Firefighters said crews protected the remaining cylinders and extinguished the fire, adding that no injuries were reported.
