He leaves behind his wife Shirley, and their three children and seven grandchildren.
From the Blue Jays' press release, CEO Paul Godfrey:
It's difficult to put into words the overwhelming sense of grief and loss shared today by the Blue Jays family, the City of Toronto, the extended community of Major League Baseball and its many fans. Tom Cheek has provided the soundtrack for the most important moments in this team's history, with his choice of words and intonation always perfectly suited for the occasion. He was far more than just an outstanding announcer though. He was a great goodwill ambassador for baseball in Canada. His love for the game, which radiated through his words on the radio, captivated fans across this country and helped to grow the sport from one coast to the other.
A Web site, www.tributetotom.com , has been created in Tom's memory where fans are encouraged to purchase a "Tribute to Tom Tribute Wrist Band" where net proceeds will go to the Canadian Cancer Society.
Vaya con dios, old friend. We were truly lucky to have shared so many summers with you.
