That varies from place to place. In first nations communities and some provinces nurses can say they would like it to be prescribed and they will call the physician. In situations where there are provinces that enable nurse practitioners to practise, they can make that decision.
Other provinces, such as British Columbia, are working toward a system so that registered nurses in isolated communities can make that decision. The nurses are licensed by the province and therefore under provincial jurisdiction.
We're comfortable that if an individual needs Tamiflu in a remote and isolated community they will get it if required.
