The CBC has surrendered the licences of 14 Eureka 147 DAB transmitters, and the Canadian Radio-television and Telecommunications Commission has revoked those licences.
There were two transmitters authorized in Windsor, Ontario, and four each in Toronto, Ottawa, and Vancouver. The Toronto transmitters were first authorized in 1998; the Vancouver outlets in 2000; and the Windsor and Ottawa stations in 2002.
They never got much traction. Receivers were few and expensive. Of course, the USA went with a different standard, which eliminated any chance for economies of scale to reduce the price of a digital receiver in Canada.
DAB is still [b]allowed[/b] in Canada, and there are still other-than-CBC transmitters operating. I doubt that will be the case much longer though. IBOC is now allowed in Canada as well. However, I know of no more than three Canadian stations using it.
