The Canadian is a member of the International Boxing Association (AIBA) Executive Committee and also chairs the governing body's Technical and Rules Commission.

Fiacco was also appointed as the interim AIBA administrator as part of the new leadership of the organisation.

AIBA last month installed long-serving vice-president Gafur Rakhimov as their interim President, following the departure of Italy's Franco Falcinelli as temporary leader.

Falcinelli had himself replaced Taiwan's CK Wu in 2017, following an ongoing crisis at the organisation and claims of financial mismanagement. 

Rakhimov appointed Tom Virgets as AIBA's executive director, with the American having previously served as the chair of the AIBA Disciplinary Commission.

AIBA have welcomed the appointment of Fiacco as the technical delegate for Tokyo 2020, succeeding Helmut Ranze, who held the role for Rio 2016.

"AIBA has full confidence that his experience and knowledge of the sport of boxing will contribute to the great success of these Games," an AIBA statement read.

The appointment comes despite concerns over boxing's place at Tokyo 2020, with the IOC warning that they could remove it from the Games amid concerns over the sport's governance.

IOC President Thomas Bach highlighted a series of issues surrounding AIBA after the IOC Executive Board meeting earlier this month in Pyeongchang.

Chief among them is the appointment of Rakhimov as interim President despite his alleged links to organised crime.

An investigation into AIBA governance by the IOC is currently ongoing, run by its chief ethics and compliance officer, Paquerette Girard-Zappelli.

Among the problems cited by Bach in the organisation were the "preparations for the Extraordinary Congress in Dubai and the way the new leadership was, I cannot say elected, but promoted or installed".

Rakhimov was chosen to replace Falcinelli at the AIBA Extraordinary Congress in Dubai last month after the Italian interim leader decided to step down.

He has repeatedly been named as a mafia boss in the media although he has never been prosecuted for anything.

Last month, however, he was among 10 individuals the United States Treasury announced they were imposing sanctions on because they were allegedly associated with the alleged Eurasian criminal entity, the Thieves-in-Law.

AIBA claimed the 66-year-old was moved to the role in accordance with their statutes.

The IOC have also expressed concerns around a lack of "clarity" around finances, the failure of an approved project to reform the referees system and the absence of a "robust anti-doping programme".

Bach also said they have not yet accepted AIBA's claim that no bouts at the 2016 Olympic Games in Rio de Janeiro were affected by match-fixing.

AIBA must deliver a report by April 2018 to the IOC.

The world governing body have already described the IOC response as "extremely disappointing".

They hoped the IOC would "have understood that the processes necessary to implement even more measures requires more time and that the positive steps already taken in recent times are evidence of AIBA's strong efforts and willingness to reform".
