I think it was, in the case of the surgeon general's resources, but doctors and nurses are not plentiful in the armed forces. It was appropriate to use that very small number of CAF members, but deploying members of the army, navy and air force that have nothing to do with health care was not appropriate.
If I remember correctly, army units were deployed in Quebec. It quickly became clear that they were able to provide support but could not be used long term. If memory serves, the Red Cross ended up taking over.
