Avery Hayward Haines (born 28 November 1966) is an American-born Canadian television journalist, and currently managing editor, investigative journalist, and host of CTV newsmagazine series W5. Born in New Mexico, United States, Haines and her family then moved to India where they lived for six years before returning to North America. Her career as a reporter began with CFRB radio in Toronto.
 CTV Newsnet
 In late 1999, Haines began to work as a fill-in anchor for CTV Newsnet.
 On 15 January 2000, Haines made a mistake with a line while taping a report introduction. After regaining her composure, she made a joke but the camera was still on. Haines retaped the segment, but later that day, a CTV technician mistakenly aired the tape that included the error and the comment. "I kind of like the stuttering thing. It's like equal opportunity right? We've got a stuttering newscaster. We've got the black, we've got the Asian, we've got the woman. I could be a lesbian-folk-dancing-black-woman stutterer. In a wheelchair ... with a gimping, rubber leg. Yeah, really. I'd have a successful career, let me tell you." On 17 January, Haines was fired from CTV Newsnet after her comments sparked controversy. 
 The unnamed technician was suspended.
 City TV
 Haines was soon hired by Citytv Toronto as a health reporter with CityNews. In fall 2001, she began hosting Health on the Line, which aired on Life Network and Discovery Health for five seasons.
 On 15 September 2010, Haines returned to Citytv as a senior reporter and anchor. Beginning on 26 January 2012, Haines wrote and hosted the award-winning Inside Story on Citytv.
 In 2016, Haines began to produce and shoot her own documentaries. Whilst volunteering on a medical humanitarian mission to post-Ebola Liberia, she produced a documentary highlighting the plight of chimpanzees that were abandoned following years of experimentation by a U.S. research laboratory. Haines also interviewed the former Warlord Charles G. Taylor's wife and current vice-president of Liberia, Jewel Howard Taylor producing a documentary called My Penpal: The Warlord's Wife. The following year, during the final offensive against the Islamic State of Iraq and the Levant (ISIS) in West Mosul, Haines was embedded with the Iraqi Special Forces in an abandoned mosque that had previously served as an ISIS headquarters. Both documentaries were nominated for RTDNA awards, and, 'Two Kilometres to Terror: Life and Death Under ISIS,' was awarded the '2018 RTDNA Dave Rogers Award for Long Feature (Large Market)'.''
