In Ontario, it is legal to turn left on a red light when turning:

  1. From a two-way street to a one-way street, after coming to a complete stop and yielding right of way to other cars in the intersection.

  2. From a one-way street to a two-way street

  4. From a one-way street to a one-way street

In Ontario, it is only legal to turn left on a red light when turning from a two-way street to a one-way street.

Overall, the key factor in determining the legality of turning left on a red light in Ontario is whether the street you are turning onto
