Dear Peter:
Firstly: Two new frequencies up here are: 860.8125 which is Province of Nova Scotia wide on TMR for all Ambulance calls. Their dispatch centre is in Bedford.
Secondly: 860.6625 is the new TMR frequency for Dept. of Natural Rescouces province wide in Shubenacidie
Thirdly: The RCMP are going to this system in January with a scrambler on the system.
Lastly: re: 911 I don't know much about New Brunswick yet. But in Nova Scotia the main PSAP Centres are Yarmouth, Halifax, Sydney, Truro run by the RCMP and a private PSAP in Kentville run by Valley Communications.
The 911 centre in Yarmouth covers the following counties in Nova Scotia: Annapolis, Digby. Yarmouth, Shelburne and Queens. (They in turn forward all ambulance calls to the centre in Bedford.) They handle the RCMP calls themselves, and the Fire calls are forwarded to fire dispatch centres as follows:
Digby Municipal Airport does 1/2 Annapolis County and 3/4 Digby County.
The Yarmouth Fire Department Dispatch Centre dispatchs the rest of Digby County, all of Yarmouth County and 1/2 of Shelburne County (Municipality of Barrington) for a total of 23 Departments.
The rest of Shelburne County is done by Roseway Hospital in Shelburne about 10 departments.
Queens County is done by a private company in Bridgewater which does Lunenburg County.
Valley Communications in Kentville does the rest of Annapolis County, Kings County and 1/2 of Hants County and also a couple of Local Town police forces.
Halifax Regional Municipality and the rest of the Hants County are done by the HRM Fire Dispatch Centre in Bedford at the New Fire Hall where the HRM 911 centre is.
Northern Nova Scotia covered by the 911 centre in Truro has private companies that do the fire departments as well as some fire departments do there own.
Cape Breton is done by a regional centre in Sydney as well as private companies.
The Emergency Medical Care Inc. also known as Emergency Health Services in Bedford that does all Ambulance dispatching for the province has put forth a proposal to take over some dispatching for small fire departments that still do there own, once the TMR radio system is on line for fire departments.
The Yarmouth FD dispatch centre takes the calls from 911 or call forwarded by the fire departments old in-house emergency numbers and then pages the appropriate department via a phone line dedicated to their paging system.
Also the Ambulances and the RCMP by the first of the year (2001) are going to have computers in the cars to get information and for GPS tracking.
In PEI there are 3 Dispatch centres - in Charlottetown, Summerside and RCMP. They are just conming on stream after the kinks are worked out. The 911 centres just call forward the calls to the local fire or ambulance service. There are no known regional fire or ambulance dispatch centres in PEI except maybe in Charlottetown. I hope this may help as it is quite lengthy and most is from memory. Thanks again and nice to hear from you.
