You can turn left on a red light if you are in the left-most lane of a one way street, you're turning into the left-most lane of a one way street, and no nearby signs prohibits the turn.

Explanation:

The law is quite clear about it, a car can turn while the traffic light is red, as long as it respects passersby and there are no signs that prohibit turning.

The prohibition of this turn will only be indicated with the correct signaling.

So, if there is no signaling and you respect pedestrians, you can use the left turn with all the precautions taken, and it is something that the law expresses to accelerate traffic.
