DMR used by some municipal services; some NXDN used by VFDs around Lunenburg (fireground ops) and STC buses in HRM
No Provoice. In fact I believe our only EDACS system went silent about 10 years ago.
Also Motobro is used at Hfx Airport and possibly Marine Atlantic in North Sydney
DMR and NXDN are still on my "works in progress" list.
