Many Canadians, especially older ones who grew up when Canada was still a very high-trust society, have what could be described as a reverence for authority figures. This involves a significant degree of obedience, bordering on subservience.
Medical professionals are often among the most revered authority figures to these Canadians, even to the point of being seen as infallible. There are Canadians who won't question any advice made, nor any suggestions given, by these medical professionals.
If a medical professional were to recommend euthanasia to these kind of Canadians, even if it wasn't something that they really wanted to do, I think a significant proportion would feel obliged to go along with it, as irrational as this may seem.
This attitude became quite apparent over the last three years, when many Canadians completely bought into the many obviously nonsensical, and sometimes even outright harmful, policies being pushed by medical professionals and public health officials.
At the same time, however, those three years have been a significant eye-opener for some Canadians, too. For these people, the trust they once had in the various medical professions was completely shattered.
With a larger proportion of the Canadian population no longer trusting Canada's medical professionals and health care systems, it doesn't surprise me at all that we're starting to see more questioning of policies such as this one.
