There is always a danger with exhaustive lists. The more elements we list, the more we will think that it is exhaustive and are likely to limit ourselves to that list. We would certainly not want to leave some situations out.
You are right, it is not only about the health and financial situation, but those two personal circumstances, together with age in those cases, are the easiest to understand; they are the clearest. Of course, the list of examples provided in Bill C-36 is not exhaustive or restrictive, and other personal circumstances could be considered. There is nothing stopping that.
