Steve Blacklock started officiating in Guelph in 1980 and quickly ascended up the ranks. In 1984 he was selected to officiate at the provincial championships, his first in what would be an impressive run of twenty-five straight appearances. At the national level, Steve officiated at nineteen Canadian ringette championships and the past five Canada Winter Games, where he was consistently selected to officiate in the final games. In 1994 and 2004, Steven was also selected to officiate at the world ringette championships.
Off the ice, Steve has devoted much of his time to help develop officials and the officiating program. He has served on the Ringette Canada Officiating committee for a number of years and has also served as the rule book editor for two significant periods of rule changes.
