He had a tremendous season with the Astros scoring seven goals for the club. He would return to the Supra in 2005, and bring his career to a culmination with another run with North York, and Toronto. Dos Santos also had a stint in the National Professional Soccer League with the short lived expansion franchise the Toronto ThunderHawks during the 2000–2001 winter indoor season. He helped the ThunderHawks reach the postseason by finishing second in the National Conference, and reached the Conference finals where they were defeated by the Milwaukee Wave.
