The cold hard truth about Toronto's transport network

With a population of 2.8 million, projected to grow to 7 million by 2050, Toronto is Canada’s most populated city. While its cultural, social and financial cachet skyrockets, one thing may soon hold it back – it’s public transport system.

Academic Caren Levy argued in 2013 that the ability to access transport reflects the “right to participate” in the life of the city – not just to exist in it, but to partake fully of what it offers, for work, leisure and education. Toronto’s public transport system has struggled to keep up with the growth of the city, and the demands that places on its infrastructure.

Ridership has dropped in recent years because of concerns over expense, comfort and even practicality – the stress that the transit system is under has rendered it inefficient and time-consuming. Add in the fact that a highway runs right through the centre of the city and that most of the public transport converges downtown, and it’s a recipe for disaster.

Scholars, community organisers and local politicians have long since called for an expansion of public transport. In 2010, during a local election, concerned citizens residing around poorly serviced areas began the self-explanatory “Subways! Subways! Subways!” campaign, and the projected population growth of the greater Toronto area has led the Toronto Transit Commission (TTC) to promise extensions of the Metrorail subway system, although there has been controversy about whether the extension will reach the right places.

The city's transport woes have much to do with how public transport system was set up in 1849. The first bus routes started taking passengers between Yorkville and St.Lawrence Market, which are located in the centre of the city. Toronto has expanded outwards from there, and so too did Toronto’s transit network, which has led to the current concentration of the most transport links downtown, often around the most wealthy areas.

There are three main components to Toronto’s public transport system (not including the GO trains for suburban travellers that link into the city centre).

The primary system is the subway, which is structured around Line 1 (Yonge-University) that runs in a U, and Line 2 (Bloor-Danforth), which intersects the U at the centre of the city. Other, more recent additions include Line 3 & Line 4, both of which cover specific parts in the north and east of the city that were previously only covered by infrequent bus services. A cursory glance at the subway map transposed on to Toronto shows the lack of coverage in certain areas of the city - meaning that if you don’t live directly on a subway line, you have to get buses to your nearest stop.

The lack of coverage outside downtown Toronto and a few very specific pockets of the city has led to the establishment of the GO trains that take commuters directly from specific suburbs in the Greater Toronto and Hamilton Area (GTHA) to various central subway stations, but the bus coverage to get to these stations outside of the city proper is even more inferior than within the city centre itself.

The buses come every twenty or so minutes, and are often the only way of getting to a subway station, particularly some that are further out. The result is that during rush hour, they can be jam-packed, leading people (and sometimes children) to wait in freezing temperatures for the next one in the hope of more space. Some of the most recent figures from the TTC highlight that only 68.1 per cent of buses arrive on time. These issues are often exacerbated by traffic congestion on the roads in and out of the city.

Perhaps one of the most confusing parts of Toronto’s transport system is that streetcars comprise a significant part of it – Toronto’s streetcar system is the busiest and geographically, largest, light rail system in North America. While it sounds like a good idea – after all, this is a region with major transport problems – the streetcar runs on the same roads as the cars, meaning it has to stop for red lights, and around 50 per cent of streetcars are late. There’s even a very busy intersection downtown where a streetcar driver has to get out and manually change the tracks because other streetcars run on it.

A study in 2017 found that a monthly transit pass in Toronto, known as a PRESTO card, is among the most expensive in the world at  $150 (£88.40), despite the fact that Toronto’s public transport leaves so much to be desired. A student card is not that much cheaper at $130. And despite recent population growth, Toronto does not operate a zoning system like most other major metropolises – which means that a ride between two stops anywhere on the line will set you back the same amount - $3 for adults, and $2 for concessions.

These shortcomings when the city is growing so rapidly have made transport a hot topic at local elections, not least because it exacerbates a problem with income inequality which is already among the worst anywhere in North America. A comprehensive report from the Martin Prosperity Institute points out that the fractured nature of Toronto’s public transport might as well have generated different towns with differing standards of living.

Another report from the City Institute in York University in 2015 echoed this sentiment, emphasising that the “capillaries” of public transport in Toronto are left to waste away even if they do have some coverage, while prime spaces benefit from continued investment. These capillaries can be found away from downtown and wealthier areas, and instead run throughout the “inner suburbs”. A series of maps, from J.D. Hulchanski’s income polarisation study, clearly demonstrates that transportation systems don’t really cover the areas that might rely on it the most.

As a city lauded for its diversity, you would hope that Toronto’s public transport system would be geared up to cope with the dynamic between immigrants and public transit – not least the simple fact that immigrants tend to be the most prominent users of public transport the world over. In reality, much of Toronto’s immigrant population, comprising significant numbers of service and low-wage workers, live in those underserved inner suburbs, referred to in policy documents as Neighborhood Improvement Areas. These spaces without service have created what is now referred to as “transit deserts”, which can have long-term effects on the health and employment prospects of people living in those areas, as a Toronto Star article demonstrated. These issues have been left to fester, and worsen, for many years, without much actual resolution.

All of this is meant to be tackled by the “Big Move” plan run by Ontario’s transport agency, Metrolinx, which aims to expand the regional transport system – adding 1,200 km of rapid transport in the area with a view to completely changing how public transport is structured. Yet groups representing disgruntled communters like Fair Riders and TTC Riders are not convinced it will solve the structural issues, and concerned it will instead simply distribute them further outwards. Given the troubles Toronto has long faced creating a transport system that works for all its residents, it is unsurprising they remain skeptical that the city’s problems - and the ones yet to come - will be solved by current thinking.


Here’s why we’re using a car wash to drill into the world’s highest glacier on Everest

For nearly 100 years, Mount Everest has been a source of fascination for explorers and researchers alike. While the former have been determined to conquer “goddess mother of the world” – as it is known in Tibet – the latter have worked to uncover the secrets that lie beneath its surface.

Our research team is no different. We are the first group trying to develop understanding of the glaciers on the flanks of Everest by drilling deep into their interior.

We are particularly interested in Khumbu Glacier, the highest glacier in the world and one of the largest in the region. Its source is the Western Cwm of Mount Everest, and the glacier flows down the mountain’s southern flanks, from an elevation of around 7,000 metres down to 4,900 metres above sea level at its terminus (the “end”).

Though we know a lot about its surface, at present we know just about nothing about the inside of Khumbu. Nothing is known about the temperature of the ice deeper than around 20 metres beneath the surface, for example, nor about how the ice moves (“deforms”) at depth.

Khumbu is covered with a debris layer (which varies in thickness by up to four metres) that affects how the surface melts, and produces a complex topography hosting large ponds and steep ice cliffs. Satellite observations have helped us to understand the surface of high-elevation debris-covered glaciers like Khumbu, but the difficult terrain makes it very hard to investigate anything below that surface. Yet this is where the processes of glacier movement originate.

Scientists have done plenty of ice drilling in the past, notably into the Antarctic and Greenland ice sheets. However this is a very different kind of investigation. The glaciers of the Himalayas and Andes are physically distinctive, and supply water to millions of people. It is important to learn from Greenland and Antarctica, – where we are finding out how melting ice sheets will contribute to rising sea levels, for example – but there we are answering different questions that relate to things such as rapid ice motion and the disintegration of floating ice shelves. With the glaciers we are still working on obtaining fairly basic information which has the capacity to make substantial improvements to model accuracy, and our understanding of how these glaciers are being, and will be, affected by climate change.

Under pressure

So how does one break into a glacier? To drill a hole into rock you break it up mechanically. But because ice has a far lower melting point, it is possible to melt boreholes through it. To do this, we use hot, pressurised water.

Conveniently, there is a pre-existing assembly to supply hot water under pressure – in car washes. We’ve been using these for over two decades now to drill into ice, but our latest collaboration with manufacturer Kärcher – which we are now testing at Khumbu – involves a few minor alterations to enable sufficient hot water to be pressurised for drilling higher (up to 6,000 metres above sea level is envisioned) and possibly deeper than before. Indeed, we are very pleased to reveal that our recent fieldwork at Khumbu has resulted in a borehole being drilled to a depth of about 190 metres below the surface.

Even without installing experiments, just drilling the borehole tells us something about the glacier. For example, if the water jet progresses smoothly to its base then we know the ice is uniform and largely debris-free. If drilling is interrupted, then we have hit an obstacle – likely rocks being transported within the ice. In 2017, we hit a layer like this some 12 times at one particular location and eventually had to give up drilling at that site. Yet this spatially-extensive blockage usefully revealed that the site was carrying a thick layer of debris deep within the ice.

Once the hole has been opened up, we take a video image – using an optical televiewer adapted from oil industry use by Robertson Geologging – of its interior to investigate the glacier’s internal structure. We then install various probes that provide data for several months to years. These include ice temperature, internal deformation, water presence measurements, and ice-bed contact pressure.

All of this information is crucial to determine and model how these kinds of glaciers move and melt. Recent studies have found that the melt rate and water contribution of high-elevation glaciers are currently increasing, because atmospheric warming is even stronger in mountain regions. However, a threshold will be reached where there is too little glacial mass remaining, and the glacial contribution to rivers will decrease rapidly – possibly within the next few decades for a large number of glaciers. This is particularly significant in the Himalayas because meltwater from glaciers such as Khumbu contributes to rivers such as the Brahmaputra and the Ganges, which provide water to billions of people in the foothills of the Himalaya.

Once we have all the temperature and tilt data, we will be able to tell how fast, and the processes by which, the glacier is moving. Then we can feed this information into state-of-the-art computer models of glacier behaviour to predict more accurately how these societally critical glaciers will respond as air temperatures continue to rise.

The ConversationThis is a big and difficult issue to address and it will take time. Even once drilled and imaged, our borehole experiments take several months to settle and run. However, we are confident that these data, when available, will change how the world sees its highest glacier.
