Did I miss Canada embarking on a policy of euthanasia? I know that the treatment of native people had quite a few scandals in recent decades, did you want to allude to that?
Without wanting to make light of that situation, I think it is rather different in scale to what you propose.
This kind of euthanasia (voluntary, with a review board, like in Switzerland) is something I feel should be a human right, though I'm not sure about the intricacies of the Canadian system.
I think one should be very much aware of the extreme chasm between this and the kind of euthanasia committed in the early half of the last century in the third Reich, and not confuse them because of the common name. From the grandparent comment, I had assumed they meant to imply that Canada had implemented something closer to the latter.
It's not as bad as what I believe China might do if worst comes to worst.
But from what I have heard the Canadian system has issues, with cases of especially permanent sick+poor people being in some cases constantly "nudged" to say good by even if they still have a strong will to live. Through I'm not sure how wide spread such issues had been and if they where fixed.
The reason I mention it is because china would also claim it's fully free choice, then if that isn't enough start nudging and then if that isn't enough go further.
Lets just hope it won't happen.
