Well, it is a giant traffic jam, and for the last little while, turns haven't been allowed. If you are going directly through, you just have to brave the lane restrictions and traffic.
People who turn north on Bayview cut onto Bruce Park to by-pass the intersection via Roehampton. People who turn south on Bayview cut onto Soudan. Many people going straight through the intersection east-west also use Soudan-Parkhurst to reach Laird.
As a local resident, I am definitely not a fan of cars using these residential streets as a by-pass. They are usually the impatient types, and have no problem flooring it down Bruce Park, for instance, which is on a hill (so sight lines limited) and doesn't have sidewalks on one-side of the road so often has dog walkers or moms with strollers on the street.
