also the site of several boat clubs, an amusement park, an airport, and a small residential area. The Western Gap is a wide channel allowing western access to the Inner Harbour. The gap is deep enough (over 31 metres) to allow large ships (like lake freighters) to enter and exit into the Inner Harbour. The Billy Bishop Toronto City Airport is located on the south side of the channel and is accessed by ferry and tunnel. Before the Western Gap was dug in 1910, the waterway was wide with a shallow sandy shoal surrounding what became Hanlan's Point. The sands were deposited on either side of the new channel and are part of the airport lands. The Eastern Gap is an approximately wide passage between Ward's Island and the western edge of the Port Lands and used by most freighters to enter into the inner harbour and port facilities. The gap was first formed from 1852 to 1858 when storms caused a break in the sandy spit that connected the area with the mainland. Prior to the 1800s, small boat users had to use a portage on the western end of the sandy spit peninsula (thus requiring them to travel a short distance on land) from Lake Ontario to the inner harbour. After 1858, the Harbour Trust made the temporary channel into a permanent waterway. Outer Harbour Toronto also has a second harbour, referred to as the Outer Harbour. The City of Toronto's Cherry Beach (formerly Clarke Beach Park), located on the north side of the Outer Harbour, is popular in summer. It typically meets high water quality, environmental and safety standards. A proposed Lake Ontario Park by Waterfront Toronto would pass through the Outer Harbour. The City of Toronto operates a marina in east end of the Harbour. Eight community water-sport clubs, forming the independent Outer Harbour Sailing Federation, share a small strip east of Cherry Beach Clarke Beach Park. The clubs are: Hanlan's Boat Club, Mooredale Sailing Club, Outer Harbour Centreboard Club, Saint James Town Sailing Club, Toronto Multihull Cruising Club, Toronto Windsurfing Club, Water Rats Sailing Club, and Westwood Sailing Club. The harbour was developed in the 1950s and 1960s by the Toronto Harbour Commission through the construction of a new breakwater called the Outer Harbour East Headland. At that time, it was expected that there would be a great upswing in the number of ships calling
