As the Regiment's newest Garrison, Fort Conestoga has its origins along the Grand River and serves the population west of Metropolitan Toronto and mainly in the Kitchener-Waterloo, Cambridge, Guelph, Burlington vicinity. Recognized in June 2002 as an Outpost of York Garrison, Fort Conestoga received official Garrison status at a Regimental Mess Dinner held October 19, 2005 at the Officer's Mess of the Royal Highland Fusiliers of Canada. Charitable status was granted early in 2006.

In creating its in inaugural statement of objectives, Fort Conestoga has committed to use its charitable contributions not only in the furtherance of the objectives of the 78th Fraser Highlanders (the preservation of Canadian military history and associated Scottish traditions), but also to assist charitable organizations of similar fabric. The RHF of C Regimental Trust and their efforts to outfit soldiers and their pipe band in highland dress is one such initiative, and secondly, a sponsorship commitment has been made to the Canadian Battlefield Foundation and their development of the Point 67 Memorial and historic battlefield viewing area in Normandy.

Through the efforts of Captain Anthony Lea, 2IC, the Garrison has developed a good relationship with the local OHL Kitchener Rangers hockey club. Using “The Year of the Veteran” in 2005, as an impetus, an opening ceremonies tribute to veterans past and present was launched. A special silent auction program was created in conjunction with this very moving event. This has resulted in significant benefit to a number of organizations which the Garrison has chosen to support as part of its mandate to remember not only the past, but to also be mindful of the present. In addition to the organizations mentioned previously, beneficiaries have included the KW Poppy Fund in support of veterans and the London Military Family Resource Centre in support of soldiers in Afghanistan. In addition to the organizations mentioned previously, beneficiaries in support of veterans have included the KW Poppy Fund, the London Military Family Resource Centre, the Wounded Warrior Fund, and Ste. Anne's Hospital Foundation. Since 2003 in excess of $40,000 has been distributed to all of these organizations.
