She does not have Capacity. The fact she is a legal adult, conscious, and free of mental impairment does not equate to having Capacity.
Justice Roberts' judgement makes this clear. She absolutely refuses to accept her diagnosis despite multiple sources being in agreement, so she can not claim to be making informed decisions about her own care.
She does not acknowledge that even attempting to travel to Canada, irrespective of whether treatment is available or not, will inevitably kill her before she even gets there, which is in itself proof that she is not making rational decisions and therefore can not be deemed to have Capacity.
