The incident showed the effectiveness of demanding fire and smoke safety standards in underground rail systems. Only the e-bike owner and one other passenger sustained non life-threatening injuries from the bike battery fire and other passengers escaped safely when the train stopped at Sheppard-Yonge Station. The metro line was able to rapidly re-open after evacuating the impacted train. Fire protection engineers and scientists underline that smoke control and material fire resistance standards applicable in underground transit systems ensured that the fire did not spread to seats and that smoke from the burning battery did not inhibit evacuation of the train or the station.
