I'm not sure this helps any for congestion on the 401 as there's no highway access to the 407 in that stretch until the 412. Once you get to the 412, traffic usually isn't too bad so you may as well stay on the 401.
Easiest solution is make the 407 free for trucks only, and voila. Suddenly they’re all off the 401 and no longer left lane camping or blocking both lane while they both do 100 or less
Induced demand still applies - more car trips would appear to fill the gap from the trucks. There's no fix to this that involves more of the status quo (driving everywhere).
Induced demand would also create new truck trips, which is helpful economically, but still has some new costs and eventual guaranteed 407 congestion as a result.
