2) What do you do if there's no opportunity to turn before the light turns yellow? And even more so, what if cars blow through the yellow and red light and you now cannot turn and are blocking traffic in the opposite direction?
1) It's more important to position your vehicle so that your wheels are straight and you can see past opposing left turning traffic. You can move as far in as you'd like. But you'll have a sharp turning radius if you move too far in.
2) Turn the car even if the light is yellow/red. You have to wait for all oncoming vehicles to come to a complete stop. If you see someone not braking, and planning to blow the red; you have to wait for them. Even though what they're doing is illegal, if you collide... you will be found at-fault and charged for turning left without safety.
Legally as long as you're in the intersection past the white line when the light is green, you can complete the turn whether you're now facing yellow or red. Remember that it's only illegal to enter the intersection against a yellow & red.
It's also important that you complete the turn without blocking cross-traffic, because that's also illegal: http://www.e-laws.gov.on.ca/html/statut ... .htm#BK250
You're going to get mixed advice on this, but some people believe there should only be one vehicle waiting to turn left inside an intersection at one time. That will mean in some cases one vehicle will be turning left for every single traffic cycle. Practically, that's never going to happen in urban areas. For the test, you can play it safe and just have one vehicle in the intersection at one time.
https://www.youtube.com/watch?v=LXFq69VCD9U Here's an interesting video of where you see the corolla driver positioned at the wrong place in the intersection. He places himself such that the opposite left turning traffic will block his view. His wheels/vehicle are turned to the left, so if he were rear-ended he'll be going straight into oncoming traffic.
In this case there is plenty of room in the intersection, for at least for two cars.
When he completes the turn, he makes it illegal by going into the wrong lane. Unfortunately, this is the norm in the Greater Toronto Area.
