CBC/RC are still on the air. CBC on 88.5, RC on 95.1.
You're not going to see them go back to AM. Pretty much the only audience that would benefit would be in the U.S., but it's not Americans' tax money that's going to finance the CBC.
If these frequencies are reactivated (and I do mean *if*), IMHO they're going to be reactivated by existing stations moving from elsewhere on the AM dial.
I know CBC/SRC is on 88.5 and 95.1, but I'm talking about CBC/SRC reactivated the AM frequency and simucast 88.5 and 95.1 like they did in Vancouver, Calgary and Edmonton.

"adma" posted the better answer.....
but I'll waste a few keystrokes & chime in anyway...
Firstly, in the Western cities (also Regina, Saskatoon, and Winnipeg) the AM transmitters were never silenced. In Montreal, they'd have to reactivate frequencies they'd given up.
More importantly, on the Prairies, the AM transmitters provide useful extra coverage in areas where even a 100kw FM in the city couldn't go. A quick look at the map of Saskatchewan suggests if CBK-540 were silenced, it would take at least seven new high-powered FMs to replace the lost coverage. In Alberta, I'd suggest at least seven new large FMs to replace the 740 and 1010 coverage. Three at least for Winnipeg.
In the Montreal area, the FMs
were already there. Ottawa, Sherbrooke, Trois-Rivieres, plus a bunch of smaller ones. Every place 690 went that 95.1FM didn't, was already covered by some existing FM.
Actually, the CBC wanted to shut down the Vancouver AM transmitter. CRTC wouldn't let them.
