In 1980, the station was purchased by Leader Broadcasting and adopted the call sign CJLB.

On November 2, 1994, CJLB was given approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to convert to FM.

[4] On July 14, 2009, Newcap announced it would be selling CKTG and sister station CJUK-FM to Acadia Broadcasting for $4.5 million CAD plus working capital.

[5][6][7] In early October 2010, CKTG-FM changed its format again, to adult hits, playing a variety of music "From the '60s, 70's, 80's and beyond", and re-branded as The New Giant FM.

When atmospheric conditions are right, CKTG can be heard across Lake Superior in Munising and Marquette, Michigan.
