O'Ree, who became the first black player in the NHL, debuting with the Boston Bruins on Jan. 18, 1958, posed for photos, autographed a wooden hockey stick for Trudeau and even showed off his Hall of Fame ring during his visit to Parliament Hill.
The two discussed O'Ree's upbringing in Canada, his move to the United States, his current position as the NHL's diversity ambassador and his work with the Hockey is for Everyone programs.
The visit, where O'Ree was accompanied by his wife Deljeet and daughter Chandra, was organized for "Willie," a documentary chronicling the story and upbringing of O'Ree, which is scheduled to be released in 2019.
