There are the usual conditions that an officer has in making a decision.
As I spoke earlier, they're looking at the response to the procedural fairness letter that was sent out. The family may dispute the medical condition, the prognosis, and bring their own specialist reports to bear in relation to the condition and the expected health and social services the individual may need over the next five years. For the social services side, then, after the Supreme Court decision in Hilewitz and De Jong, they can present one of their mitigation strategies for not having the same impact.
For example, if someone is going to be employed in Canada and the employer has a health care plan that will cover expensive prescription medications, that could be a mitigation plan. The officer would take that into account and say that expensive medication is covered off by their health care plan, so they find they're not medically inadmissible.
Generally, then, on the temporary resident permit, humanitarian and compassionate grounds are powers that officers have all the time, as does the minister.
