Lake Rosseau is located in Ontario, Canada, about 200 km (120 mi) north of Toronto.

Pratts Point and Rosseau House were well known and although the hotel was destroyed long ago, the vista and scenery remain.

[2] Many notable people have owned cottages on the lake, including Goldie Hawn, Ted Rogers, William Eli Sanford, Martin Short, Lillian Massey Treble and Steve Yzerman.

[3] The President of the United States, Woodrow Wilson (1913–1921), frequently holidayed on Lake Rosseau, and eventually bought Formosa Island and Royal Muskoka Hotel (in 1901).

There is a curious story that in 1914 he signed the register of the Bala Bay Inn after the outbreak of World War I; however, there is no official record of the president being in Canada at that time.
