Scrubb's career is perhaps the most accomplished in the history of Canadian Interuniversity Sport basketball. In 2010, Scrubb joined a powerhouse Carleton Ravens team at Carleton University that had won the Canadian men’s university basketball championship in six of the previous eight years. He averaged 13.1 points per game, and helped the Ravens to a perfect 22-0 record, and their seventh national championship. Scrubb was named an OUA East Second Team All-Star, and earned the Dr. Peter Mullins Trophy as CIS Rookie of the Year. In his second season at Carleton, Scrubb led the Ravens to another 22-0 season, and earned the Mike Moser Memorial Trophy as the Outstanding Player in the CIS. He also was awarded the Jack Donohue Trophy as MVP of the CIS Championship Tournament, as the Ravens took the national title again. Scrubb won his second Moser Trophy the following year, and took the award again after the 2013–14 season. He is the only three-time recipient of the award in CIS history. In his final season at Carleton, Scrubb led the Ravens to their fifth consecutive national title, and earned his second Donohue Trophy as playoff MVP. He also was selected First Team All-Canadian for the fourth consecutive year. During his five years at Carleton, the Ravens had a won-lost record of 102-3. He and his brother Thomas dominated CIS basketball during their time with the Ravens.
