There are a number of things, and I'll certainly defer to Renee on this one.
From my perspective, because these are two private companies, they are not subject to freedom of information, so we do not know in fact how decisions are made. If the government makes a decision, we know. If NavCan tells us they can't do this for safety reasons and they can't fly this way, but then two or three years later it's doable, if we had known in the beginning how that decision was made and we had insight into that....
However, they're private companies, so our level of oversight would involve some access to freedom of information that would allow our elected MPs, especially, to understand how NavCan and GTAA makes those decisions behind closed doors. That is the key.
When we find out after decisions are made, there may be consultation, but it's a fait accompli.
