CKOC is a Canadian radio station, broadcasting at 1150 AM in Hamilton, Ontario. The station airs a classic hits format branded as Classic Hits 1150 CKOC and is owned by Bell Media. CKOC is a 50,000 watt, Class B station operating on a Regional (not clear-channel) broadcast frequency, with transmitters located near Empire Corners in Haldimand County, about 25 kilometers (15 miles) south of Hamilton. CKOC's studios are located on Upper Wentworth Street (next to Lime Ridge Mall) in Hamilton.


Early History[edit]

CKOC is the oldest continuously-operating radio station in Canada, on the air since May 1, 1922. Station CHAB, in Moose Jaw, Saskatchewan, began broadcasting a week earlier, on April 23, 1922, and is still on the air today -- but was shut down for a period of time in 1933 before re-opening.

Originally, CKOC's station was based in the Lower City at the corner of King William and John Streets and was an offshoot of the Wentworth Radio and Supply Company owned by Herb Slack. He figured he could sell more radios if he also owned a radio station and in the spring of 1922 the station became only the third radio station in all of Canada. Other broadcast locations over the years for CKOC include, the 11th floor of the Royal Connaught Hotel in the downtown core, the Lister Block building on James & King Williams Streets and the a studio on Garfield Avenue near King & Sherman Avenue North.[1] During its early years, the station broadcast on a number of frequencies, including 880, 630 and 1120 kHz; the station moved to its current frequency of 1150 in 1941.

Later History: Top 40 and Oldies formats[edit]

CKOC featured a Top 40 music format from 1960 to 1992, and increased its power to 50,000 watts in 1979.

On February 17, 1992, after a countdown of the Top 500 hits of all time (a long-running annual tradition at the station), CKOC debuted "Oldies 1150" with the new calls CKMO ("More Oldies"). However, on April 2, 1993, the station reverted to the heritage CKOC calls, admitting that dropping the calls in the first place had been a mistake and that the station's listeners wanted the original calls back. The station mentions its Top 40 heritage on the air as part of the current oldies format, with liners such as, "The station that played 'em then... plays 'em again." The current branding started sometime in late 2006.

From 1928 to 1955, the call letters CKMO were used at a pioneer radio station in Vancouver. From 1993 to 2012, the CKMO call sign was again used at a radio station in Victoria, British Columbia. In 2014, the CKMO call letters are currently used at a radio station in Orangeville as CKMO-FM.

CKOC first applied for an FM station in 1968, but the FM station did not take to the air until 1986 as adult contemporary station CKLH.

CKOC Today[edit]

CKOC currently airs a schedule of primarily local programming during the day and evening, with CHAM-sister-station import Mike Nabuurs, taking on morning hosting responsibilities from 5:30am to 9:00am, Paul Morris from 9:00am to 2:00pm and Rob White hosting from 2:00pm to 7:00pm. The rest of the station's music programming consists of automated "55 Minute Music Marathons" from 7:00pm and into the overnight. Syndicated programming includes reruns of the 1970s-era American Top 40 on weekend evenings.

In mid-June 2013, after Vinyl 95.3 switched formats from Classic Hits to hot AC, CKOC added more 1970's and 1980's music to its lineup. It was the first time since February 1992, when the station changed its format, that any music later than the 1970s has been played on the station, a trend mirroring most other oldies outlets in North America, which have moved away from the oldies positioning and have adopted classic hits approaches. The station has dropped the "Great Oldies" reference and now refers to itself as "Classic Hits 1150 CKOC".

CKOC has suffered from much co-channel interference from CJRC in Gatineau, Quebec at night, particularly in Southwestern Ontario and north of Toronto which received a relatively clear signal for CKOC during the day. In these areas, CKOC was almost impossible to pick up on some nights due to CJRC. This interference was remedied in Spring 2007, when CJRC moved to the FM dial and closed the AM signal.

In 2012, CKOC, known as one of "Canada's Oldest radio stations" turned 90 years old. [2] [3] [4]

On November 4, 2014, the CRTC approved an application by Bell Media Radio to modify CKOC's facilities from a five-tower day pattern and a ten-tower night pattern with a transmitter power of 50,000 watts to a six-tower operation with a daytime transmitter power of 50,000 watts and a night-time transmitter power of 20,000 watts.
