I'll add to what Mr. Berger said. I think the expert report of Dr. Madeline Li in the Lamb case is quite instructive on this. She actually developed and oversees the MAID program at the University Health Network in Toronto. In her expert report, she describes the case of a woman who had bone cancer and depression. She was assessed by two experienced MAID providers, not by her oncologist and a psychiatrist, and they approved her for MAID. She changed her mind during the 10-day waiting period and decided to do palliative care instead.
Later, during another crisis, she requested MAID again and her MAID providers decided again that she was eligible. They apparently had no concerns about her ambivalence. Then she ended up changing her mind again during the next waiting period. You're talking about the waiting period not mattering as a protection. This is right there in an expert report by someone who designed the system in Toronto. It's quite remarkable. I recommend looking at that expert report.
