Road design, safety and Vision Zero

[SammyOES]

Does anyone know what the rules are when there is a traffic light for a pedestrian crossing at an intersection, but the traffic light doesn't cross one of the roads at the intersection? I'm specifically thinking about the intersection at Albert and Seagram here.

Albert is North-South, and there is a traffic light across Albert that turns red after the pedestrian button is pushed. Immediately to the south of the light Seagram T-intersects Albert, I think with a stop sign. To the south of Seagram there is a stop line for northbound traffic on Albert.

When the light is green it's obvious what everyone should do. When the light is red:
1. Do cars turning from Albert northbound to Seagram need to stop? They are facing a red light and making a left turn, which suggests yes, but if the traffic light only controls the pedestrian crossing then it shouldn't affect them.
2. After stopping at the stop sign, do cars turning from Seagram to Albert northbound need to wait for the light to turn green, or can they turn once the crosswalk is clear?

There was almost an accident here last night when a car ran the red light turning left from Albert onto Seagram. There was honking and I just heard the turning driver yell “it’s allowed”. I’d never heard or seen this theory before so started looking it up online and of course it’s been discussed here.

It seems 100% obvious that the left turn is prohibited on red because there’s a stop line for the turn lane. A stop line that doesn’t exist for turn lanes where you don’t have to stop for a light/sign.

But I’d never really thought about how bad this intersection is and it definitely needs to be rethought now that there’s a lot more housing around there.
