Big Tub Lighthouse is an active lighthouse located near Tobermory in Bruce Peninsula, Ontario, Canada. The lighthouse was originally lit in 1885 and is still used up to this day. The lighthouse was originally built in 1885 when the Department of Marine bought the lots for the lighthouse and John George and David Currie constructed the lighthouse to prevent anymore ship accidents as the entrance to the Tobermory Harbour was hard to navigate and was often used as an asylum from bad weather. The lighthouse has a focal height of 13.2 metres (43 ft) and has a range of 11 nautical miles (20 km; 13 mi).
