South Shore District Health Authority, Nova Scotia (1211) is combined with South West Nova District Health Authority (1212) and referred to as “South Shore—South West Nova (1210)”
Colchester East Hants Health Authority, Nova Scotia (1234) is combined with Cumberland Health Authority (1235) and referred to as “Colchester East Hants—Cumberland (1230)”
Pictou County Health Authority, Nova Scotia (1246) is combined with Guysborough Antigonish Strait Health Authority (1247) and referred to as “Pictou County—Guysborough Antigonish Strait (1240)”
