The reality, as Mr. Fybush so well put it, is that the major markets will only have one or two viable AM stations nowadays, and this is true in the United States as well. In Detroit, the U.S. market I'm most familiar with, WJR 760 and WWJ 950 both do very well in the ratings. The rest of the AM stations have pretty much fallen off the map, especially since WXYT 1270 began simulcasting on a full-power FM.
Some quick ratings for AM across Canada:
Montreal Anglo
CJAD (800) 26.3
CINW (940) 2.6
CKGM (990) 2.0
Montreal Franco
CKAC (730) 5.7
CINF (690) 1.1
Ottawa Anglo
CFRA (580) 11.1
CFGO (1200) 2.7
CIWW (1310) 1.7
Toronto
CFTR (680) 8.0
CFRB (1010) 4.2
CFMJ (640) 2.7
CJCL (590) 2.7
CFZM (740) 2.3
CHUM (1050) 0.1
Hamilton
CHML (900) 6.8
CKOC (1150) 4.5
CHAM (820) 1.1
St. Catharines
CKTB (610) 5.7
Kitchener-Waterloo
CKGL (570) 6.8
London
CJBK (1290) 4.1
CFPL (980) 3.1
CKSL (1410) 1.9
Windsor
CKLW (800) 18.8
CBE (1550) 4.3
CKWW (580) 2.3
Winnipeg
CJOB (680) 16.2
CBW (990)* 11.3
CFRW (1290) 2.1
Calgary
CHQR (770) 9.9
CBR (1010)* 7.3
CFAC (960) 3.7
CFFR (660) 3.3
CKMX (1090) 2.5
Edmonton
CHED (630) 11.6
CFCW (790) 5.3
CBX (740)* 4.1
CFRN (1260) 2.4
CHQT (880) 1.9
Vancouver
CKNW (980) 13.8
CBU (690)* 6.9
CISL (650) 4.7
CKWX (1130) 4.4
CKST (1040) 3.9
CFTE (1410) 1.3
CHMJ (730) 0.8
Victoria
CFAX (1070) 13.5
* These are the CBC stations with nested FM transmitters, so some of this listening would be on FM.
As is seen from these numbers, some markets have one or two dominant AM stations but the others aren't pulling much in. I'd expect Rogers to do something with 1310 in Ottawa, most likely attempt a news/talk/sports format - the station has the Blue Jays which of course Rogers owns. I don't have as much confidence in the future of some of the other low-rated AM stations across the country, especially CKSL in London.
