Shubenacadie Grand Lake — known locally simply as "Grand Lake" and called Kji-qospem in Mi'kmaq, meaning "grand lake" — is a vast and diverse freshwater lake straddling the boundary of Halifax Regional Municipality and Hants County on mainland Nova Scotia. With a surface area of 1,841 hectares and a maximum depth of 45 metres, it is the seventh and largest lake in the historic Shubenacadie Canal system, which was originally engineered to transport goods from Halifax Harbour all the way to the Bay of Fundy. The lake drains northeastward into the Shubenacadie River, connecting it to a rich and historically significant watershed long used by Mi'kmaq people to travel between seasonal hunting and fishing grounds. Today, Grand Lake is recognized as one of Nova Scotia's premier trophy fisheries, designated as a Special Bass Management Area, and is best explored by boat given its considerable size and depth.
