Toronto's PATH: how the underground walkway works, and how to find your way in it

On a January morning, a lot of downtown Toronto never goes outside. People walk from Union Station to an office tower, down to lunch, across to a bank branch and back, all below the street. They are using the PATH, the downtown walkway network that most visitors discover by accident and most new residents learn one corridor at a time.

It is easy to use once you understand what it is: not one building, and not a single system with one owner, but dozens of private basements and concourses joined together. This note explains how it fits together and how to get around it with confidence. Every figure comes from the City of Toronto and the Toronto Financial District BIA, listed at the end.

What the PATH is

The City describes the PATH as a mostly underground pedestrian network in downtown Toronto spanning more than 30 kilometres of restaurants, shopping, services and entertainment. Its own figures give a sense of scale:

• more than 75 buildings are connected to it;
• six subway stations, three major department stores, nine hotels and Union Station, the city's busiest transit hub, can be reached through it;
• there are 1,200 restaurants, shops and services in about 3.7 million square feet of retail space;
• it handles more than 200,000 business-day commuters, as well as tourists and residents.

City Hall and Metro Hall are connected, and so are several of downtown's big venues: the City names the Hockey Hall of Fame, Roy Thomson Hall, Scotiabank Arena and the CF Toronto Eaton Centre. In broad terms, the City says you can walk from the waterfront to Downtown Yonge, and from the Entertainment District across to Yonge Street.

Why it feels like many places at once

The single most useful fact about the PATH is who owns it. According to the City, each segment is owned and controlled by the owner of the property it runs through, and about 35 corporations are involved. The City's role, set by Council in 1987, is to co-ordinate.

That explains almost everything that confuses first-time users:

• The look changes every few hundred metres, because you are walking from one building's concourse into the next.
• Access depends on the building. The City's PATH page does not publish one set of opening hours for the network. Because each stretch belongs to the building it runs through, a corridor that is busy at noon on a Tuesday may be closed on a Sunday evening.
• Restaurants and shops keep their own hours, separate from the corridor that passes them.

The practical rule follows: treat the PATH as a weekday, daytime network, and if you are travelling early, late or on a weekend, have a street-level route ready in case a link is closed.

The network is also older than it looks. The City traces it to 1900, when the T. Eaton Co. built a tunnel between its main store and an annex; by 1917 there were five tunnels downtown, and in 1927 a tunnel joined Union Station to the Royal York hotel. Most of what you walk through today was added much later, building by building.

How the signs work

New wayfinding was installed throughout the PATH in spring 2018, according to the City. The Toronto Financial District BIA, which looks after the PATH map, describes the system as easy-to-understand coloured pathways, with destination markers that point to major places. "Waterfront", for example, shows the route south toward Lake Ontario.

In practice, the signs that matter are the destination names: Union Station, a street name, a tower, a landmark. Read the overhead sign, pick the destination closest to where you are going, and follow it. You will see the PATH logo, a word made of four coloured letters, on signs and at entrances from the street.

Before you go: get the map

The City publishes the official PATH map as a downloadable PDF, and the BIA's own answer to "is there an app?" is plain: there is currently no app for the PATH map; downloadable maps are available. Save the PDF to your phone before you go underground. Satellite positioning does not reach below the street, so a phone's map app can easily place you in the wrong building.

The official map shows building names, the streets above, and the connections between them. Use it to plan your route as a list of buildings, not as a line: "Union Station, then this tower, then that one, then up to King Street." That is how the signs will present it.

Getting oriented: habits that work

Know the streets above you. The official map draws the street grid over the walkways. Note which street you went down from, and which one you want to come up at.

Use Union Station as your anchor. It is the network's busiest connection, linked to trains, the UP Express and the bus terminal, and it is well signed from most of the downtown core. If you get turned around, follow the signs back to Union and start again.

Come up for air. If you are lost, take the nearest exit to street level, find a street sign, and go back down. It takes two minutes and saves twenty.

Allow extra time. Underground routes are rarely straight. A trip that is three blocks at street level can involve several turns, corridors and changes of level below it.

Accessibility

The BIA says the PATH maps are designed to help people with accessibility needs by marking where the level changes and showing alternate step-free routes such as ramps, and that the colours on maps and signs follow the recommended 70 per cent contrast level. The official map also marks accessible routes through some of the larger complexes.

Because each section belongs to a different building, the step-free option can be inside the building rather than in the corridor itself, and it may close when the building does. If you depend on a step-free route, check the map for level changes before you set out, and allow time for a detour.

When the PATH is worth it

The PATH earns its place on the coldest, wettest and hottest days, and at lunchtime, when it is the quickest way to reach a lot of food without crossing traffic. It is less useful on weekends and evenings, and for long distances, when a subway ride or the street is often faster.

A simple way to start: on the next cold weekday, walk from Union Station to the Eaton Centre underground with the map open. Once you have done one route end to end, the rest of the network starts to make sense.
