Re the Canadian plan, it is exactly what I had proposed sometime in some thread on this board. Kick MCAS out of the aircraft and train for the issues of stick force linearity or pitch up tendencies due to engine location or whatever the aerodynamic aberrations are. If that training requires a new type rating, then so be it.
My LA4-200 Lake Amphibian would pitch down with power and up when you decreased the throttle due to the rear facing engine located more or less at the CG. Exactly the opposite of every other aircraft that I had flown. That aerodynamic tendency was covered on day #1 of training.
