As the Supreme Court said:
Where the Minister is considering an application for exemption for a supervised injection facility, he or she will aim to strike the appropriate balance between achieving the public health and public safety goals.
What this means is it's not possible to assign a specific weight to any one of the 27 factors in and of themselves. The totality will be there before the minister, and he or she, at the time, will decide, based on that totality of information, what the appropriate decision is. Of course, a decision is always subject to judicial review.
