Path (stylized as PATH) is a network of underground pedestrian tunnels, elevated walkways, and at-grade walkways connecting the office towers of Downtown Toronto, Ontario, Canada. It connects more than 70 buildings via of tunnels, walkways, and shopping areas. According to Guinness World Records, Path is the largest underground shopping complex in the world, with of retail space which includes over 1,200 retail fronts (2016). As of 2016, over 200,000 residents and workers use the Path system daily with the number of private dwellings within walking distance at 30,115. The Path network's northern point is the Atrium on Bay at Dundas Street and Bay Street, including a now-closed tunnel to the former Toronto Coach Terminal, while its southern point is Waterpark Place on Queens Quay. Its main north–south axes of walkways generally parallel Yonge and Bay Streets, while its main east–west axis parallels King Street. There is continuous expansion of the Path system around Union Station. Two towers being built as part of CIBC Square will be linked to the Path system, extending it to the east to cross over Yonge Street by a pedestrian bridge into the Backstage Condominium building (Esplanade and Yonge corner), giving closed access to Union Station, Scotiabank Arena, and other buildings in Toronto's Financial District. History Early pedestrian tunnels In 1900, the Eaton's department store constructed a tunnel underneath James Street, allowing shoppers to walk between the Eaton's main store at Yonge and Queen streets and the Eaton's Annex located behind the (then) City Hall. It was the first underground pedestrian pathway in Toronto and is often credited as a historic precursor to the current Path network. The original Eaton's tunnel is still in use as part of the Path system, although today it connects Toronto Eaton Centre to the Bell Trinity Square office complex on the site of the former Annex building. Another original underground linkage, built in 1927 to connect Union Station and the Royal York Hotel, remained an integral part of the Path network for many years until it was replaced by a newer connection between the Royal York Hotel and Royal Bank Plaza, which continues onward to Union Station. Expansion The network of underground walkways expanded under city planner Matthew Lawson in the 1960s. Toronto's downtown sidewalks were overcrowded, and new office towers were removing the much-needed small businesses from the streets. Lawson thus convinced several important developers to construct underground malls,
