In remote regions of the Northwest Territories, Nunavut and the Yukon, community and public health nurses often serve as the initial point of care for most primary care services, and provide most of the well-child care, while family physicians tend to more acute or chronic cases. This is also the case in some rural/remote parts of Canada. In other provinces and territories, public health nurses are involved in post-partum care for families of newborns, and in delivering prenatal and early childhood development programs. As children reach school age, the role of public health nurses tends to be more focused on immunizations.
