I also had a nice drive to a small island on the north basin of Lake Winnipeg called Matheson Island. A cable guided ferry links the island to the mainland. On the island there is a nice little beach and a quaint fishing village.
An interesting one is Glover Island in Grand Lake, the largest lake in Newfoundland. Remote and uninhabited, it's 24.2 miles long and 3.2 miles wide. Glover Island contains a number of ponds and lakes, and the largest contain islands themselves. Each of these has the distinction of being an island in a lake on an island in a lake on an island.
Manitoulin Island. Separating Georgian Bay from the rest of Lake Huron, it is the largest Freshwater Island in the World. Largest Island in a Lake. Contains the largest lake in a Lake (Lake Manitou, 104sq mkm). Contains the largest Island on a lake on an Island in a Lake (Treasure Island in Lake Mindemoya, on Manitoulin Island, in Lake Huron....Treasure Island reputedly contains several ponds).
I visited last year, but I am too lazy to post photos.
