Document 15: 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.
