In 1946, Cavalaris took out his trainer's license, working with his father, who had a couple of horses in Detroit. In the mid-1960s, he ran Canada's most powerful public stable. He led Canadian trainers in wins in 1966 (although that was a tie), 1969, 1970, 1972, 1973 (also a tie), and 1976. In 1966, Cavalaris led North American trainers with 175 winners.[citation needed]
Some of Cavalaris' most noteworthy clients were Allen Case, Peter D. Fuller, George R. Gardiner, Margaret Seitz, and Joan Reid.[2] Among the most famous horses he trained were Cool Reception, Henry Tudor, Ice Water, and Victorian Era. He was also the trainer of Dancer's Image, who won the 1968 Kentucky Derby on the track but was disqualified two days later due to testing positive for traces of the pain-killer phenylbutazone, a substance later made legal by the Kentucky Racing Commission.[3]
In 1969, Cavalaris became Gardiner's exclusive trainer. In 1976, he directed Gardiner to record earnings of $639,816 (over $100,000 more than the previous record in Canada that Cavalaris also set). This was one of eight money-winning titles in the space of 11 years. Other famous winners he trained were Arctic Blizzard, Carney's Point, Chatty Cavalier, Double Quill, Haymaker's Jig, James Bay, Mary of Scotland, Monte Christo II, Orbiter, Plegada, Prompt Hero, The Knack II, Two Violins, Vindent de Paul, and Yukon Eric. His last winner, in June 1996, was Major Pots, owned by Gardiner.

Retirement
Cavalaris turned in his trainer's license in 1978. At that point he became the Ontario Jockey Club's racing secretary for a decade. Following that he went back to training. And in 1996 he retired once more.
