Writing emails to politicians (as one does) and I'm stumped, which federal minister am I most likely to get to care about American private company space debris falling on Canada?

Public safety?
Science/innovation?
Foreign affairs?
International development?

All of the above?? I'm not really expecting any response, but I'm still trying to make someone in the federal gov't care a tiny bit about space debris and the SciAm article seems like a good excuse to do that.
