To my best understanding, the problem is that the answers to precisely these questions are currently ambiguous. For instance, NATO article 5 is not clear if it would apply, under what circumstances it would apply and what aspects, other than the five space treaties to which Canada is a signatory, would apply in this domain. This is precisely why the UN has proposed an open-ended working group on capabilities and a separate one on behaviours. There is a problem of agreement on the parameters of those working groups, but I'm confident that they will get off the ground in the very near future. Canada, of course, needs to be prepared to be a very active player, as hard as it's going to be to get an international consensus.
