The station was originally owned by the family of Jean Pouliot, then-owner of CFCF. It was acquired by Cogeco in 2001 concurrently with Cogeco's acquisition of the network. As an owned and operated station of the network, CFJP was part of V's takeover by Remstar Corporation.
CFJP formerly had a rebroadcaster in Rimouski, CJPC-TV channel 18, but this switched to being a semi-satellite of CFTF-TV in June 2007.
CFJP launched a high definition simulcast on June 4, 2007 available on Videotron and Cogeco cable in Quebec. It signed on over the air on channel 42 from their studio building in Montreal in December 2007. However, through the use of PSIP, digital television receivers display CFJP-TV's virtual channel as 35.1. After the analog television shutdown and digital conversion on August 31, 2011, CFJP-TV moved from its pre-transition channel number, 42, to its post-transition and old analog channel number, 35. Because of the placement of the digital broadcast antenna at a low elevation on top of a residential building in Montreal, the coverage area was greatly reduced as compared to its former analog signal, which broadcast from Mount Royal. Many viewers were no longer able to receive CFJP. The station moved its digital transmitter to Mount Royal on April 16, 2013, greatly increasing its coverage area.
