On 5 August 2008 Kanaykin and his training partners
Sergey Morozov,
Viktor Burayev, and
Aleksey Voyevodin, who are all coached by
Viktor Chegin, were banned from competing for two years by the
World Anti-Doping Agency (WADA) after testing positive for EPO. The positive tests were conducted in April 2008 and evidenced doping. He took the silver in men's 20 km race walk in 1:20:27 at the
2011 World Championships in Athletics in
Daegu. On 20 January 2015, Kanaykin was disqualified for life starting from 17 December 2012, and all his results between 25 January 2011 and 25 March 2011, as well as between 16 June 2011 and 27 September 2011 were annulled. On 25 March 2015 the IAAF filed an appeal with the Court of Arbitration in Lausanne, Switzerland, questioning the selective disqualification of the suspension periods of the six athletes involved including Kanaykin. On 24 March 2016 the court ruled and disqualified all of Kanaykin's results from 11 February 2011 to 17 December 2012. ==International competitions==
