In Ontario, under what condition is it legal to turn left on a red light?

In Ontario, it is legal to turn left on a red light specifically when turning from a two-way street onto a one-way street. This rule allows for greater traffic flow and efficiency, provided it is safe to do so. Drivers must ensure that the way is clear and that there are no pedestrians or oncoming vehicles in conflict with their turn.

This provision is designed to promote safety and minimize stops when the left turn can be made without risk to other road users. It's important to remember that the driver must come to a complete stop before making the turn, check for any signage, and ensure that the turn can be completed safely.

In contrast, turning left on a red light in other scenarios, such as turning from a one-way street to a two-way street or from other configurations, is not permitted. There may not be the same level of safety due to the potential for conflicting traffic or pedestrian movement. Additionally, even when turning left on a red light is allowed, drivers must always be cautious and yield to pedestrians.
