William Wylie was born July 15, 1928 in Galt, Ontario. After spending two seasons with the Brantford Lions of the Ontario Hockey Association--Junior B--the 5'7", 145-pound forward was a member of the Galt Red Wings of the Ontario Hockey Association Junior "A" Hockey League for the 1946-47 season and the Galt Rockets in 1947-48.
Wylie joined the Quebec Aces of the Quebec Senior Hockey League for the 1948-49 and 49-50 seasons, accounting for 90 regular season and 15 playoff points, before making his NHL debut with the New York Rangers the following season.
The New York Rangers dressed Wylie for one game during the 1950-51 National Hockey League season. Held pointless in his lone game, he split the rest of the season with the Saint Paul Saints of the United States (Pro) Hockey League and the New York Rovers of the Eastern Amateur Hockey League where he was an EAHL Second Team All-Star.
Wylie was a member of the AHL's Cincinnati Mohawks in 1951-52, before spending the next five seasons with the Vancouver Canucks of the Western Hockey League. During his five years with Vancouver, Wylie and the Canucks were on two occasions runners-up for the President's Cup, awarded to the Western Hockey League's champions.
After spending five years in the WHL, Wylie joined the Kitchener Dutchmen of the Northern Ontario Hockey Association for the 1957-58 season leading them to the 1958 Allan Cup tournament. He returned to Kitchener for the 1958-59 (NOHA) and 1960-61 (Ontario Hockey Association Senior "A" Hockey League) seasons before returning to Galt where he finished his playing career.
The 1960-61 season was a homecoming of sorts for Wylie, returning to Galt as a member of the Galt Terriers and leading them to the 1961 Allan Cup championship. He played two more years with the Terriers before calling it a career.
In his career, he played in only one NHL game, that with the New York Rangers during the 1950-51 season. He passed away in 1983 at the age of 55.
