Owned and operated by the Quebec Remparts QMJHL franchise, it broadcast on 800 kHz with a power of 50,000 watts as a class B station from a site near the Chaudière River near Saint-Étienne-de-Lauzon in Lévis, using a very directional antenna (six towers) with the same directional pattern day and night to protect various other stations on the same frequency, including CJAD in Montreal (which is approximately 250 kilometres (160 mi) away).

On August 9, 2007, Corus announced a deal to sell the station to a group of local businessmen, namely Michel Cadrin, Jacques Tanguay and Patrick Roy, owners of the Remparts.

CHRC announced it would cease operations at the end of the month of September 2012, at the same time discontinuing the last AM radio service from Quebec City.

Before leaving the air at 6:06 p.m., the station's final words broadcast were farewell messages from their staff.
