After ending his first stint with AAA El Canek turned up in International Wrestling Revolution Group (IWRG) next, who promoted shows in Naucalpan, where El Canek used to main event during his UWA days. Early on he worked a program with Rayo de Jalisco Jr. over the WWA World Heavyweight Championship held by Rayo de Jalisco Jr. While in IWRG he also defended the UWA World Heavyweight Championship, a title he still claimed despite the UWA being inactive for eight years at that point in time. On May 5, 2005 El Canek and Rayo de Jalisco Jr. faced off against Perro Aguayo Jr. and Head Hunter I in a match where the winning team would then wrestle for the vacant IWRG Intercontinental Heavyweight Championship. Canel and Jalisco Jr won the match, then El Canek defeated Rayo de Jalisco Jr. to become the 13th over all IWRG Intercontinental Heavyweight Champion. Canek would defend the championship twice in 2006, against Rayo de Jalisco Jr. and eternal rival Dr. Wagner Jr. Late in the year Canek's knees had deteriorated to a rate where he had to take time off to have reconstructive surgery and then rehab and as a result only wrestled sporadically from 2007 to 2009, not just for IWRG but in general. While he was inactive IWRG did not vacate the Heavyweight title, but also did not promote it while El Canek was not working for them. El Canek returned to IWRG in 2009, bringing the championship belt back with him. Canek and El Hijo del Canek won a father/son tag team tournament that took place on December 20, 2009 defeating El Hijo del Pantera and Pantera, Exodia Olímpico,
