Yonge StreetYonge Street is a major arterial route in the Canadian province of Ontario connecting the shores of Lake Ontario in Toronto to Lake Simcoe, a gateway to the Upper Great Lakes. Until 1999, the Guinness Book of World Records repeated the popular misconception it was 1,896 km (1,178 mi) long, and thus the longest street in the world; this was due to a conflation of Yonge Street with the rest of Ontario's Highway 11. Yonge Street (including the Bradford-to-Barrie extension) is actually 56 kilometres (35 mi) long. The construction of Yonge Street is designated an Event of National Historic Significance in Canada. Yonge Street was fundamental in the original planning and settlement of western Upper Canada in the 1790s, forming the basis of the concession roads in Ontario today. Once the southernmost leg of Highway 11, linking the provincial capital with northern Ontario, Yonge Street has been referred to as "Main Street Ontario". Today, no section of Yonge Street is a provincial highway.The street was named by Ontario's first colonial administrator, John Graves Simcoe, for his friend Sir George Yonge, an expert on ancient Roman roads. Yonge Street is a commercial main thoroughfarerather than a ceremonial one, with landmarks such as the Eaton Centre, Yonge-Dundas Square and the Hockey Hall of Fame along its length—and lends its name to the Downtown Yonge shopping and entertainment district.In Toronto and York Region, Yonge Street is the north-south baseline from which street numbering is reckoned east and west. The eastern branch of Line 1 Yonge–University serves nearly the entire length of the street in Toronto and acts as the spine of the Toronto subway system, linking to suburban commuter systems such as the Viva Blue BRT. As Toronto's main street, Yonge hosts parades, street performances and protests. After major sporting victories thousands of people will gather on the downtown portions of the street, particularly near Dundas Square, to celebrate and the street will be closed to vehicular traffic while those are occurring. Streetcars on routes crossing Yonge in that area (Carlton, Dundas, Queen, King) during those celebrations will often have to cease operations a few hundred metres east or west of Yonge Street due to the crowds. In recent times, these celebrations particularly occurred after the Toronto Blue Jays won the World Series of Baseball in 1992 and 1993, when the Canadian men's hockey team defeated the United States for the Olympic gold medal in 2002, 2010 and 2014, and when the Toronto Raptors won the NBA championship in 2019. During these celebrations motorists drive up and down the other portions of the street honking their horns and flying flags and during lesser celebrations (when the crowds have not closed down the street) they will do this along the downtown portions of the street as well. 19.Which of the following statements about Yonge Street is NOT true?
