The emergency department at Roseway Hospital in Shelburne will be temporarily closed Wednesday. Officials with the South West Health Authority indicate the closure is due to the sudden and temporary unavailability of a physician. The closure will span for a twelve hour period between 8 a.m. to 8 p.m. Shelburne area residents requiring emergency services during the hours of closure should visit the nearest open emergency department or collaborative emergency centre. The public is reminded to dial 911 in the case of a health emergency.
