The Canadian Open, organized by Golf Canada, was first contested in 1904.

Played annually continuously since then, except during World War I and World War II, the Canadian Open is the third oldest continuously running tournament on the PGA TOUR, after The Open Championship and the U.S. Open.

Only two players have been able to capture golf’s Triple Crown (consisting of winning all three National Open titles in the same season); they are Lee Trevino (1971) and Tiger Woods (2000).

As a national open, the event had a special status in the era before the professional tour system became dominant in golf.

The top three golfers on the Mackenzie Tour – PGA Tour Canada Order of Merit prior to the tournament are given entry into the Canadian Open.

Celebrated winners include Leo Diegel, Walter Hagen, Tommy Armour, Harry Cooper, Lawson Little, Sam Snead, Craig Wood, Byron Nelson, Doug Ford, Bobby Locke, Bob Charles, Arnold Palmer, Kel Nagle, Billy Casper, Gene Littler, Lee Trevino, Curtis Strange, Greg Norman, Nick Price, Vijay Singh, Mark O’Meara, Jim Furyk, Tiger Woods and Jason Day, just to name a few. The Canadian Open is regarded as the most prestigious tournament never won by Jack Nicklaus, a seven-time runner-up.
