CJOH-DT – Wikipedia

CJOH changed its branding to “CTV Ottawa” in 2005, when CTV’s owned-and-operated stations began to stop using their callsigns within each station’s branding. The newsroom was destroyed by a four-alarm fire during the early morning hours of February 7, 2010, destroying equipment and the news archives.
