The original Frontenacs were coached by James T. Sutherland, played in the intermediate division of the Ontario Hockey Association (OHA), and won the inaugural J. Ross Robertson Cup during the 1898–99 season.

[3] National Hockey League alumni from this team are Alec Connell, Bill Cook, Allan Davidson, and Flat Walsh.

National Hockey League alumni from this team are Mickey Blake, Glen Brydson, Bill Cook, Gus Giesebrecht, Doug Stevenson, Charles Stewart, Carl Voss and Flat Walsh.

[citation needed] Some members of this team then formed an entry in the Ontario Veteran's Hockey League during World War II.

National Hockey League alumni from this team are Hub Macey, Gus Marker, Walt McCartney and Ed Nicholson.

During the summer of 1972, the QMJHL had threatened a lawsuit against the OHA to force the Junior Canadiens to return to the Quebec-based league.

[4] After a one-year hiatus, the OHA then reactivated the suspended franchise under new ownership and with new players, calling the team the Kingston Canadians.

[4] The new Kingston team was essentially an expansion franchise promoted from the OHA's Tier II league, that had only common name to share with the old Junior Canadiens.

The Tier II Frontenacs originated in the Eastern Junior B Hockey League and date back to at least the early 1940s as the Kingston Victorias.

However, in some OHA histories (such as the annual Media Guide) the Kingston team is still shown as the legitimate successors of the Junior Canadiens' legacy.

[6] The Frontenacs franchise has the second-longest championship drought in the OHL (to the Sudbury Wolves by one year), and the fourth-longest in the Canadian Hockey League.

[7] During the inaugural season of the Kingston Canadians in 1973–74, Jack Bownass was awarded the Matt Leyden Trophy as OHA Coach of the Year.

Mavety returned to Kingston in 1997 to become the head coach once again, and stayed in that position until midway through the 2002–03 season when he stepped down to focus on his general manager duties.

In 2019, Chris Clifford had his number 29 retired, joining Mike O'Connell, Brad Rhiness, Tony McKegney, and Ken Linesman in receiving the honour.
