Green arrows and transit priority signals

MTO Driver’s Handbook: Traffic Signs and Lights, Lights and arrows to help turning vehicles

Flashing green lights and green arrows direct drivers who are turning. When you face a flashing green light or a left-pointing green arrow together with a green light, you may turn left, go straight ahead or turn right from the proper lane: this is an advanced green light, because oncoming traffic still faces a red light. Pedestrians must not cross on a flashing green light unless a pedestrian signal tells them to.
