There is a certain assessment of evidence and information at all levels. In some cases, if evidence or information is not available, it is difficult to see how the minister can arrive at a conclusion. In this case there is a certain amount of information, and I think that this one is quite reasonable.
The Supreme Court does not require that the minister arrive at a certain conclusion, or not. The court demands that the minister take into account public health and safety considerations, and that everything be in accordance with the charter. Whether the information is there or not, she is going to have to make a decision in light of those factors.
