PATH, Toronto

PATH is a network of underground pedestrian tunnels, elevated walkways, and at-grade walkways which connect the office towers of Downtown Toronto. It links more than 70 buildings via 30 kilometres (19 mi) of tunnels, walkways, and shopping areas. According to Guinness World Records, PATH is the largest underground shopping complex in the world with 371,600 square metres (4,000,000 sq ft) of retail space which includes over 1,200 retail fronts (2016). As of 2016, over 200,000 residents and workers use the PATH daily with the number of private dwellings within walking distance at 30,115.

More than 50 buildings or office towers are connected through the PATH system. It comprises 20 parking garages, five subway stations, two major department stores, two major shopping centres, six major hotels, and a railway terminal. The CN Tower, Ripley's Aquarium of Canada, and Rogers Centre are connected via an enclosed elevated walkway, called the SkyWalk, although the walkway does not have indoor connections to these attractions.

PATH provides an important contribution to the economic viability of the city's downtown core, and is also used to supplement sidewalk capacity in downtown Toronto. The system facilitates pedestrian linkages to public transit, accommodating more than 200,000 daily commuters, and thousands of additional tourists and residents en route to sports and cultural events. Its underground location provides pedestrians with a safe haven from the winter cold and snow, as well as the summer heat and humidity.
