Canada introduces additional requirements to allow return of the Boeing 737 MAX
In March 2019, the Boeing 737 MAX passenger airliner was grounded worldwide after 346 people died in two crashes (www.canada.ca) עוד...

Having a few extra safety protocols for Canadian Airlines is a good thing but Transport Canada should have made it manditory that any carrier flying through Canadian Airspace must also comply.
That would be like a human, trying to swing a full grown elephant by it's tail..it would not happen.
The Canada requirements will require a design change, to permit PIC to disable stick shaker, in case the stick shaker activates erroneously (due to faulty Angle-of-Attack sensor). The rationale is to reduce pilot workload for that situation. All this and more are covered in the linked document.
Not according to the document which states only that colored caps should be added to the circuit breakers to disable the stick shaker. The breakers were already there.
Thanks for the clarification Greg. You dug deep into the documents.
Color coding the critical breakers keeps it simple and effective.

Ummm...most of your answer is correct. It's actually just an enhanced flight deck procedure.
"Specifically, the Canadian design changes for the Boeing 737 MAX will include an enhanced flight deck procedure that provides the option for a pilot-in-command to disable a loud and intrusive warning system (commonly called the “stick shaker”) when the system has been erroneously activated by a failure in the angle of attack sensor system. This feature will effectively reduce pilot workload given what has been learned from the two tragic accidents, and has been fully evaluated by Transport Canada’s flight test pilots.
There will also be differences in training including that associated with the enhanced flight deck procedure."
