My understanding from reading posts here and elsewhere is that, for NEXUS, Canada would have to approve such a rate increase. Is that correct? Any idea if that has a chance of happening at about the same time as the change for US-only programs, or would it likely take significantly longer?

A good thing to potentially come from this is that credit cards that as of now reimburse only TSA Pre and Global Entry should also reimburse NEXUS! That would be great!
