Leo Cavanagh first called Lloydminster "home" in May of 1947 when he began working with Husky on the construction of the first Husky asphalt refinery. By mid 1954 he was named refinery manager.

His community and civic interest resulted in the capturing a seat on Lloydminster City Council as alderman from 1963 to 1966. In 1969 he became mayor of the City, a position he held until 1970.

Transferred to Calgary in 1977, as General Manager of Refining, Led later moved to Manager of Heavy Oil Upgrading. In this capacity he supervised the heavy oil upgrading process and plant location studies. In 1982 he took early retirement and two years later, in August of 1984, the Cavanaghs resumed residence in Lloydminster.

Leo was married to Mary Howell in 1949 and together they raised five children. Ted returned to Lloydminster in 1975 to begin his teaching career in the Lloydminster Public School System. At present he teaches at the E.S. Laird Junior High School. Tom returned in 1980 to begin his medical practice at the Lloydminster Clinic, where he currently practices. In 1978 Peggy returned to the city to article with a local law firm and now is in general law practice in Vermilion. Jerry, after several years teaching in Zaire, returned to Canada in 1983 and presently teaches French at College St. Jean in Edmonton. Mary Ellen lives in Cochrane, Alberta with her husband Larry and three daughters. She still finds time to paint, which has been her long time hobby.

The Cavanagh's continuing interest in community affairs is evident in their many community and charitable activities. These include: Church Committees, Rotary, Meals on Wheels, Dr.Cooke Extended Care Centre, Hospital Foundation Board, Seniors Curling, "2003" Committee, and tutoring new Canadians in the LEARN program.

Leo passed away suddenly in March 2003.
