Nicholson Island (Lake Ontario)

Nicholson Island is a small island in Lake Ontario about 3 km west of Prince Edward County, Ontario. It is one of the islands and shoals in the Scotch Bonnet Ridge.

In 1834 Nicholson Island was under consideration as the site of a lighthouse. In 1844 nearby Scotch Bonnet Island was chosen as the site of a lighthouse. Small, low Scotch Bonnet Island's lighthouse was not fit for human occupancy during the winter, so a lighthouse keeper's house was built on Nicholson Island in 1866.

The island is currently private property, and is used as a private game reserve.
