The 25-year-old and his veteran teammate Josh Binstock kept the momentum going with a 21-12 first set win.
Uruguay's Renzo Cairus and Mauricio Vieyto attempted to steal the second set, but the top-seeded Canadians came back for a 21-19 victory to conclude the match and complete a perfect 3-0 run through the round robin.
Canada's men's and women's duos will start the knockout round on Saturday (the women also went undefeated to win their pool).
