Canadian public transit is entering a new era of propulsion, transitioning from diesel-fueled buses to smooth-running, practically silent, low-emission battery electric buses (BEBs). Some transit history buffs will be quick to point out that many forms of transit, including the trolley buses of Toronto, were once fueled by electricity, so this is merely a return to simpler days. However, the scale of this transition is going to be truly unique in Canadian public transit history.
