That's not really got anything to do with the Calgary fire department at all. Rockyview Fire Service has been undergoing some significant changes over the past few years, as detailed in the article. Springbank was initially established due to political promises and a special tax levied upon the Springbank area residents. Balzac came to be with the establishment of the new mega-mall. Chestermere has been on-and-off part of the RVFS for years now, and it's not a surprise that they're going to go with a combination paid/volunteer department (as are Springbank, Balzac, and Cochrane and Airdrie, the latter two of which are not part of RVFS). And Elbow Springs has been approved, so I hear - and it will be built along the Highway 8 area near the Glencoe golf club.
What I've heard is that Balzac will eventually have an aerial, tanker, and bush buggy to complement the pumper that exists now (along with a temporary, reserve tanker that's there now). If the Calgary Airport Authority goes ahead with its expansion plans for Springbank, it will soon require full-time, dedicated ARFF staff, which will most likely involve Springbank staff.
