Tom Henke, Allan Simpson and the late George (Dandy) Wood make up the 2011 induction class for the Canadian Baseball Hall of Fame and Museum.
They will be enshrined on June 18.
The six-foot-five Henke was known as the Terminator for his skills as a closer, playing for Texas, Toronto and St. Louis from 1982 to 1995.
Henke's 217 saves as a Jay tops the Toronto record book, and his 311 career saves are 17th best in the majors. He played eight seasons for Toronto, pitching in 446 games, winning 29, and compiling a 2.48 earned-run average.
Henke's best season with the Blue Jays was 1987, when he was named to the all-star team and led the American League with 34 saves. He helped the Jays to the World Series in 1992.
"I've always considered Toronto and Canada my favourite place to play and to help to bring home Canada's first World Series win can never be duplicated," Henke, who lives in Taos, Mo., said in a statement.
"I am truly humbled and honoured, and I can't wait to share this great news with my family and friends in Canada and in the United States."
Simpson, from Kelowna, B.C., founded the magazine Baseball America.
A former general manager of the Lethbridge Expos in the rookie-level Pioneer League, he also spent three summers with the semi-pro Alaska Goldpanners, during which time he doubled as sports editor of the Fairbanks Daily News-Miner.
He started Baseball America out of his garage. It originated with 1,500 subscribers and, 30 years later, now has a base of approximately 250,000 readers.
"This is truly a great personal honour, certainly the greatest I have ever received," Simpson, who lives in Durham, N.C., said in a statement.
"In so many ways, it validates and puts into perspective everything I have done in the baseball world. It is all the more meaningful as it is all about Canada, and I have never forgotten my Canadian roots."
Wood was the eighth Canadian to reach the major leagues, and one of only three to come from P.E.I. He played almost 1,300 games from 1880 to 1892 for Worcester, Detroit, Philadelphia, Baltimore and Cincinnati.
The Hall said Wood's Canadian citizenship was only uncovered a year ago.
Born in Pownal, P.E.I., he joins 2002 inductee Don McDougall as the only P.E.I. Hall members.
The National League's 1882 home run champion also became one of only eight Canadians to manage in the major leagues (143 games with Philadelphia in 1891), and was also one of only six Canadians to umpire in the majors (1886-98).
Wood was the first Canadian to hit for the cycle on June 12, 1885.
His lifetime batting average was .273, with 1,467 hits, 68 homers and 601 RBI.
