Brewer's final season with Prince George was his best, statistically, in the WHL. After representing Canada at the 1998 World Junior Ice Hockey Championships, he was named to the Western Conference team for the WHL All-Star Game in Regina, Saskatchewan, which he missed, as well as much of the season, due to injury. However, Brewer finished the year with 33 points in only 34 games, a near one point-per-game average, and was named to the WHL West Second All-Star Team. Brewer was the highest ranked defenceman at sixth overall among North American skaters heading into the 1997 NHL Entry Draft. He was drafted fifth overall by the New York Islanders in June 1997.
