In Canada health is constitutionally devolved to the provinces. Explicitly, since our constitution was actually written in the last 40 years so was written with the awareness that health care is a major government concern. In so far as the federal government sets health policy, it does so through the carrot and stick of federal funding through equalization and other programs. I am reasonably certain that this is also an approach the US federal government has used in areas of devolved authority (particularly education). And looking at the specific situation you're talking about, it appears the Ontario government requested military assistance, and it was granted, not the other way around. The US federal government may not have explicit authority, but the idea that it is absolutely helpless to coordinate efforts among the states (aka interstate commerce) seems kind of blatantly absurd. Never mind that they seem to, in fact, have done quite a lot of diverting masks from where they were going to elsewhere already. Just you know, not in a helpful way.
