Cornwallis Museum Needs Your Help.The Cornwallis Museum exists to keep the history of HMCS/CFB Cornwallis alive — but we can only continue this work with your support. A small donation of $5, $10, $20 or more helps preserve the stories of over 500,000 Canadians who trained at Cornwallis.Every donor will be added to our Patrons of Preservation page as a permanent thank‑you for helping keep the museum alive.
