Document 6: Canadian Open (golf): In the mid-1990s, the RCGA decided to move the championship around the country, and continues to alternate between Glen Abbey and other clubs. The owner since 2005, Clublink Corp filed an application in October 2015 to redevelop the property into a residential community, with offices and retail stores. There was no provision for a golf course in the plan. The Town of Oakville Council responded in August 2017 by declaring the golf course a heritage site under the Ontario Heritage Act. This would make it more difficult for ClubLink to develop the area as it had planned. Golf Canada was also concerned since it could not predict whether it could get the necessary permit to hold the Canadian Open at Glen Abbey in 2018 as it had planned. The dispute between the Town of Oakville and ClubLink remains before the provincial appeal tribunal. Due to this situation, the Open will be held at Hamilton Golf and Country Club in 2019.

Document 15: Men's major golf championships: The majors originally consisted of two British tournaments, The Open Championship and The Amateur Championship, and two American tournaments, the U.S. Open and the U.S. Amateur.

It is difficult to determine when the definition changed to include the current four tournaments, although many trace it to Arnold Palmer's 1960 season. After winning the Masters and the U.S. Open to start the season, he remarked that if he could win the Open Championship and PGA Championship to finish the season, he would complete`` a grand slam of his own'' to rival Bobby Jones's 1930 feat. Until that time, many U.S. players such as Byron Nelson also considered the Western Open and the North and South Open as two of golf's ``majors, ''and the British PGA Matchplay Championship was as important to British and Commonwealth professionals as the PGA Championship was to Americans.
