In 2001, Renda was part of a large group of people, including several who had ties to the Rizzuto organization, arrested as part of an investigation into illegal bookmaking.

Police sources said Renda, who was born in the U.S., used to have close ties to Gerlando Sciascia, a Mafioso who lived in Montreal for many years and was killed in New York in 1999 as part of an internal purge within the Bonanno crime family. A police source also confirmed a report, in the Journal de Montréal, that Renda was known to have ties to Salvatore (Sal the Ironworker) Montagna, a man who was believed to have been aspiring to take over as head of the Mafia in Montreal until he was killed in November on Île Vaudry, a small island just northeast of Montreal.

Police also said they believe Giuseppe Renda is not related to Paolo Renda, the brother-in-law of Vito Rizzuto, who was apparently kidnapped in 2010. Paolo Renda is still considered as missing.
