He also represented SFU at the 2005 East West Bowl held in Waterloo, Ontario.

The Battle of Happrew was a skirmish which took place around February 1304, during the First War of Scottish Independence.

The Simon Fraser Clan are the athletic teams that represent Simon Fraser University in Burnaby, British Columbia, Canada.  SFU's teams formerly played in the National Association of Intercollegiate Athletics of the United States for all sports.  In 1997, Simon Fraser sought to join the NCAA of the United States as a Division II school, but was turned down.  After this, SFU decided in 2000–01 to partially transfer to Canadian Interuniversity Sport (now U Sports).  Before the transfer, SFU did not compete in Canadian football, instead playing American football. The Frasers of Inverallochy descend from Simon Fraser, 6th Lord Lovat (c. 1572–1633), and are one branch of the Clan Fraser of Lovat, who hail from Inverallochy.  Simon was Sheriff of Inverness, and married twice.  The Frasers of Lovat descend from this first marriage, while the Frasers of Inverallochy descend from a second marriage, through a son, Simon Fraser of Inverallochy.  This Simon Fraser, 1st of Inverallochy, had a greatgrandson, Charles Fraser, 6th of Inverallochy, who was created Lord Fraser of Muchall by James Francis Edward Stuart, known to Jacobites as King James VIII of Scotland, in the Jacobite Peerage of Scotland. The Simon Fraser Student Society (SFSS) is the students' union of Simon Fraser University in Metro Vancouver, Canada.  It was founded after the opening of Simon Fraser University in 1967. Oliver Castle was a medieval tower house, located in the upper Tweed Valley in the Scottish Borders.  The site of the hillfort known as Oliver Castle is to the north of the village of Tweedsmuir, although the site of the tower house is less certain.  Mentioned in a document of c.1200, it was originally part of the line of peel towers along the Tweed Valley.  It was replaced in the seventeenth century by a house, which was itself replaced in the late 18th century by the present Oliver House.  For most of its existence the property has been owned by members of the Tweedie family. Sir Simon Fraser (21 August 1832 – 30 July 1919) was a Canadian-Australian politician, who was a member of the Australian Senate.

Simon Fraser University's men's lacrosse club also plays their home matches on Terry Fox Field, and Simon Fraser University's Department of Recreation and Athletics regularly hosts sport camps on Terry Fox Field.
