The Canadian Open is a professional golf tournament in Canada. It is co-organized by Golf Canada and the PGA Tour. It was first played 120 years ago in 1904, and has been held annually since then, except for during World War I, World War II and the COVID-19 pandemic. It is the third oldest continuously running tournament on the tour, after The Open Championship and the U.S. Open.

Lee Buck Trevino is an American retired professional golfer who is regarded as one of the greatest players in golf history. He was inducted to the World Golf Hall of Fame in 1981. Trevino won six major championships and 29 PGA Tour events over the course of his career. He is one of only four players to twice win the U.S. Open, The Open Championship and the PGA Championship. The Masters Tournament was the only major that eluded him. He is an icon for Mexican Americans, and is often referred to as "the Merry Mex" and "Supermex," both affectionate nicknames given to him by other golfers.
