Tell the truth, I'm not a fan of more traffic lights in an area w/them so close together. but the current Premier wouldn't like my preferred solution which would be to cut Yonge to one each way with cycle tracks and wider sidewalks, making car movements far more predictable.
I would also narrow Wood Street which is a whopping 14M curb to curb at Yonge, that's wide enough for a 4-lane road........that's just silly. Slash it in 1/2 to 7M.
Finally, I would put in a pedestrian refuge island on Yonge designed to block any through movement by cars from Wood to Grenville and vice versa, and to make both streets right-in, right-out at Yonge.
