Ted Dey himself played games for the Ottawa Hockey Club (as the Senators were then known) in 1887, 1889 and 1890.

The Dey's Skating Rink was the location of the first Stanley Cup win for the Ottawa Hockey Club.

In 1916, Dey first became involved in the management of the club, which had lost money during World War I.

In 1917, he bought a share of the hockey club, along with Martin Rosenthal and Tommy Gorman, the total purchase price being $15,000.

He went to live in New York City, and eventually moved in 1932 to New Westminster, British Columbia, where he later died.

At The Arena in Ottawa during World War I, he and Stanley Lewis attached red flashlights at the ends of the rinks.
