CJTR (AM) was a Canadian radio station that operated on 1140 kHz on the AM band in Trois-Rivières, Quebec. The “TR” in the call sign stood for Trois-Rivières. The station began as CKTR on February 6, 1954, broadcasting on 1350 kHz with 1,000 watts using a daytime and nighttime directional pattern. In 1958, CKTR received approval to raise power to 5,000 watts by day and 1,000 watts at night and to move to 1150 kHz. A print ad said the upgrade would take effect by October 15. In 1968, the callsign changed to CJTR, though the licensee’s name remained CKTR 1958 Ltd. On March 28, 1969, CJTR was authorized to switch from 1150 to 1140 kHz and to increase power to 20,000 watts daytime and nighttime, using a new transmitter site. The station’s nighttime directional pattern was designed to protect Class-A stations WRVA in Richmond, Virginia, and XEMR-AM in Apodaca, Nuevo León, Mexico.

Over the years, CJTR went through several format changes, owners and technical upgrades. On September 30, 1994, Telemedia and Radiomutuel merged their AM operations, closing CJTR along with six other stations (CJMS Montreal, CJRP Quebec City, CJMT Chicoutimi, CJRS Sherbrooke, and CKCH Hull). All six stations went off the air, and their licenses were turned in to the CRTC, which revoked them on November 2, 1994.
