Despite the somewhat negative coverage medical assitance in dying is really given to people with days/weeks to live as a way to skip the suffering of when your illness is not quite advanced enough to kill you, but is definitely advanced enough for the person to live in considerable pain.
It's very common among terminal cancer patients.
Stepping back, why is something outside your own cultural norms unbelievable in a general sense instead of it feeling natural to you for there to be different cultures? You don't have to agree with another culture, but why is it uncomfortable for it to exist?
There are a lot of other statistics in the reports. Recommended skimming.

According to stats Canada, in 2022 there were 334,081 total deaths (https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=131003...). There were 13,241 MAID deaths reported in Canada in 2022, according to Wikipedia (https://en.wikipedia.org/wiki/Euthanasia_in_Canada). So that's 3.96 % in 2022. So I guess the claim of 5 % is actually possible.
13241 / 334623 = 0.040
