Rádio 105.3 The New Giant FM (Thunder Bay's Greatest Hits)

CKTG-FM is a Canadian radio station, broadcasting at 105.3 FM in Thunder Bay, Ontario. The station is owned by Northwoods Broadcasting, a subsidiary of Acadia Broadcasting, and broadcasts adult hits using the brand name 105.3 The New Giant FM. "Giant" is a reference to the Sleeping Giant, a landform in Lake Superior.

The station was launched in 1944 as CFPA at 1230 kHz, an AM CBC Dominion Network station owned by local businessman Ralph Parker The station ceased airing CBC programming in 1972, adopting a country music format.

In 1980, the station was purchased by Leader Broadcasting and adopted the call sign CJLB. In 1988, the station was acquired by Newcap Broadcasting.

In 1986, CJLB received CRTC approval to add a low-power FM transmitter in Nipigon/Red Rock, Ontario on 96.3 MHz to rebroadcast the programs of CJLB Thunder Bay. CJLB applied to move Nipigon's frequency from 96.3 to 96.1 MHz and its uncertain if this was ever implemented.

In 1995, Newcap entered a local management agreement with Dougall Media, giving Dougall the right to manage the station. On November 2, 1994, CJLB was given approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to convert from the AM band to the FM band. In 1996, the station moved to its current FM frequency at 105.3 MHz.

When atmosheric conditions are right, "The Giant" can be heard across Lake Superior in Munising and Marquette, Michigan.

In 2002, CJLB-FM dropped its KIXX 105 country music format and adopted a hot adult contemporary/CHR format as Hot 105. In 2004, Dougall terminated the LMA when Newcap applied to purchase CJUK. Newcap changed CJLB's callsign to its current CKTG calls and adopted its current classic rock format as 105.3 The Giant in early 2005. In mid-2005, CFQK-FM in Kaministiquia, Ontario, located near Thunder Bay which had no affiliation with CKTG dropped their "Larry FM" variety hits format to Hot AC/CHR as "HOT FM".

On March 16, 2009, CKTG became the first radio station in Canada to carry The Bob & Tom Show, a syndicated radio show from the United States.

On July 14, 2009, Newcap announced it would be selling CKTG and sister station CJUK-FM to Northwoods Broadcasting for $4.5 million CAD plus working capital. The sale received CRTC approval on December 2, 2009.

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 rebranded as The New Giant FM.
