Willie O'Ree noted that "racist remarks were much worse in the U.S. cities than in Toronto and Montreal," the two Canadian cities hosting NHL teams at the time, and that "Fans would yell, 'Go back to the South' and 'How come you're not picking cotton?' Things like that. It didn't bother me. I just wanted to be a hockey player, and if they couldn't accept that fact, that was their problem, not mine.
In the minor leagues, O'Ree won two scoring titles in the Western Hockey League (WHL) between 1961 and 1974, scoring thirty or more goals four times, with a high of 38 in both 1964-65 and 1968-69. Most of O'Ree's playing time was with the WHL's Los Angeles Blades and San Diego Gulls. The latter team retired his number, now hanging from the rafters at the San Diego Sports Arena. O'Ree continued to play in the minors until age 43.
O'Ree was inducted into the New Brunswick Sports Hall of Fame in 1984. In 1998, O’Ree was working at the Hotel Del Coronado in San Diego, California when the National Hockey League approached him to be the director of youth development for its diversity task force. The NHL/USA Hockey Diversity Task Force is a non-profit program for minority youth that encourages them to learn and play hockey. As of the mid-2000s, O'Ree lives in Berkeley, California.
On the afternoon of January 19, 2008, the Bruins and NHL deputy commissioner Bill Daly honoured O'Ree at TD Banknorth Garden in Boston to mark the 50th anniversary of his NHL debut. In addition, The Sports Museum of New England located in TD Banknorth Garden, established a special exhibit on O'Ree's career, comprising many items on loan from his personal collection.
Those in attendance included a busload of friends from O'Ree's hometown of Fredericton. Two days earlier, the City of Fredericton honoured him by naming a new sports complex after him.
On February 5, 2008, ESPN did a special on him in honour of Black History Month.
