Cost of Scarborough Subway Extension almost doubles from initial estimate
The cost of extending the Toronto subway further into Scarborough has almost doubled, according to new estimates, which show the price of the project now stands north of $10 billion.
The Scarborough Subway Extension was first announced in 2019 as part of Ontario Premier Doug Ford's 'transportation vision,' alongside projects like the Ontario Line and an extension to the Eglinton Crosstown West.
The three-stop underground route effectively replaces the now-shuttered Scarborough RT and takes the subway almost eight km further into Scarborough.
Provincial transit agency Metrolinx's initial business case for the project pegged the cost at roughly $5.5 billion. Figures disclosed in an update for its latest board meeting show the route is now expected to cost $10.2 billion.
The agency stressed in a statement that the 2019 price was only for the construction of the route and didn't include operating costs like lifecycle maintenance of the route, which have now been added to the tally.

'As we do with all major construction projects, the initial cost estimate ($5.5B) announced in 2019 was just the estimated construction cost of the project,' a Metrolinx spokesperson said.

'The $10.2B value includes construction costs along with additional project costs, like property acquisition, technical engineering advisers, installation, testing and commissioning of all systems equipment, and interconnection with existing TTC systems.'
They said the total cost also now captures design, supply, testing and commissioning of the track, as well as an extra track running east from Kennedy Station.
Ontario NDP Leader Marit Stiles, however, said the increase was concerning.
'Ten billion dollars is not spare change, it's people's hard-earned money,' she said in a statement. 'We need a public inquiry into Metrolinx. The culture of secrecy, wasted dollars, and delays cannot continue. Something has to change.'
The Scarborough Subway Extension's cost increase follows a similar pattern to the government's signature Ontario Line.
That line was unveiled alongside the subway extension in 2019 and priced at $10.9 billion. By 2022, once contracts had been handed out, the estimate rose to between $17 and $19 billion.
Last June, the number increased again to $27.2 billion. The latest estimate included property acquisition and all operating costs, like the subway extension.

The Metrolinx spokesperson said both projects were part of a historic transit expansion in and around Toronto.
'The government of Ontario is carrying out the largest subway expansion in Canadian history to combat gridlock which costs Ontario's economy $56 billion every single year,' they said.

International Year of Glaciers' Preservation: save the glaciers!
The United Nations has designated 2025 as the International Year of Glaciers' Preservation to highlight the importance of glaciers and ensure that those relying on them, and those affected by cryospheric (1) processes, receive the necessary hydrological, meteorological, and climate services. Glaciers are crucial for regulating the global climate and providing freshwater, essential for billions of people. However, due to climate change, driven mainly by human activities since the 1800s, these vital resources are rapidly melting. The resolution calls on the international community to resolve conflicts through inclusive dialogue and negotiation in order to ensure the strengthening of peace and trust in relations between UN member states as a value that promotes sustainable development, peace and security, and human rights. Contrary to calls on the international community to resolve conflicts through inclusive dialogue and negotiation, Canada has decided to militarize the Arctic, citing the war in Ukraine as a major factor. In fact, much of the Arctic Circle is located in Russia, Canada, and Greenland. Last year the Canadian government affirmed that NORAD (North American Aerospace Defense Command) and NATO (North Atlantic Treaty Organization) will ensure Canadian sovereignty over the Arctic. However, NORAD, which is led by the United States and headquartered in Colorado Springs, is in power, while NATO is headquartered in Brussels. This decision by the federal government gives disproportionate control over the Canadian Arctic and threatens Inuit sovereignty and the balance of the already fragile Arctic ecosystem. The proposed militarization of the Canadian Arctic threatens to further weaken the ecosystem, which is being hit hard by climate change and melting ice. Dramatic changes in the Arctic, including an increase in wildfires, the greening of the Tundra and an increase in winter precipitation, are documented in the US National Oceanic and Atmospheric Administration's 2024 Arctic Report Card. The report notes a growing scientific consensus that melting Greenland and Antarctic ice sheets, among other factors, may be slowing important ocean currents at both poles, with potentially dire consequences for a much colder northern Europe) and greater sea-level rise along the U.S. East Coast. Unfortunately, the Trump administration's plan to dismantle the nation's atmospheric research programs and could set U.S. forecasting back to dark age, warns hurricane, weather and ocean scientists. We cannot negotiate with the melting point of ice, is one of the bottom lines of the report from the International Cryosphere Climate Initiative, which includes scientists from the Intergovernmental Panel on Climate Change (IPCC) and WMO's Global Cryosphere Watch network. These new findings corroborate recent WMO State of the Global Climate and State of Global Water Resources reports which also have also highlighted the alarming melting affecting the cryosphere. A glacier is a large accumulation of mainly ice and snow, that originates on land and flows slowly through the influence of its own weight. Glaciers are found on every continent. They exist in many mountain regions and around the edges of the Greenland and Antarctic ice sheets. There are more than 200 000 glaciers in the world, covering an area of around 700 000 km2 (RGI, 2023). Glaciers are considered as important water towers, storing about 158 000 km3 of freshwater (Farinotti et al., 2019). Glaciers are a source of life, providing freshwater to people, animals and plants alike. Okjkull (Icelandic pronunciation: [kjktl], Ok glacier) was a glacier in western Iceland on top of the shield volcano Ok.[2] Ok is located north-east of Reykjavik. The glacier was declared dead in 2014 by glaciologist Oddur Sigursson due to its loss of thickness. The plaque was installed on August 18, 2019,[5] with an inscription written by Andri Snr Magnason, titled A letter to the future, in Icelandic and English. The English version reads: Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it. Impact Glaciers and ice caps are critical for sustaining ecosystems and human livelihoods. They provide essential meltwater runoff during dry seasons, supporting drinking water, agriculture, industry, and clean energy production, making these frozen reservoirs vital for global water resources. Climate and cryosphere changes, however, are disrupting the water cycle, altering the amount and timing of glacier melt, causing knock-on impacts on water resource availability while also contributing to sea-level rise. As glaciers continue to shrink and snow cover diminishes, less water will be available for communities, particularly in seasonally dry regions. Increased competition for water resources is expected, with regions like China, India, and the Andes among the most vulnerable. Glaciers that have surpassed their "Peak Water" point-the stage at which meltwater runoff reaches its maximum-will gradually provide decreasing contributions to downstream water supplies, intensifying challenges for water security. Over the past century, despite representing only 0.5% of global land surface area, glaciers have contributed more to sea-level rise than the Greenland and Antarctic ice sheets. Between 2000 and 2023, glaciers are estimated to have lost an average mass of approximately 273 billion tonnes per year, which is equivalent to approximately 0.75 mm per year of global sea-level rise (The GlaMBIE Team, 2025). The continuous retreat of glaciers signals the growing impacts of global warming and creates new hazards while intensifying existing ones. For example, melting glaciers are increasing the risk of hazards such as glacier lake outburst floods, ice avalanches and glacial debris flows, posing dangers to local and downstream communities. However, risk assessments are often not possible due to an absence of data (IPCC, 2019). Therefore, increased observation of the cryosphere is critical for effectively forecasting the impacts of cryosphere-related hazards. ___________________________________________ (1) Cryospheric: The cryosphere is an umbrella term for those portions of Earth's surface where water is in solid form. This includes sea ice, ice on lakes or rivers, snow, glaciers, ice caps, ice sheets, and frozen ground (which includes permafrost).

They're still coming' (Lorrie Goldstein, June 25): Goldstein's column implies that carbon taxes or other carbon legislation would be a big cost to Canadians. Unfortunately, he doesn't understand that doing nothing about climate change is much more expensive than regulating our pollution. Think of all of Canada's coastal cities, like Victoria, Charlottetown and Halifax that are exposed to sea level rise. Think of the rising cost of rebuilding towns and cities destroyed by wildfires, like Jasper and Fort McMurray. Think of the rising insurance prices driven by an increase in unpredictable floods, fires and extreme storms. And what about the loss of life from chronic wildfire smoke inhalation, or the simple loss of the beauty and memory of a normal summer? Wake up, Goldstein, neither our lives nor our economy is possible in a burning country. Fortunately, there's a cheaper solution: Regulate our darned pollution, and yes, with taxes. This advertisement has not loaded yet, but your article continues below. Joey Maslen Calgary (It's not an implication — there will remain a massive cost to Canadians. And you can't honestly believe the billions collected have gone to fight climate change) CURBING POLLUTION Re 'Remember Carney's new carbon taxes? They're still coming' (Lorrie Goldstein, June 25): I'm being smothered by wildfire smoke, not carbon taxes. If opinion columnists spent half the time calculating the cost of climate damages as they did painstakingly following the thin thread of cost from climate legislation to taxpayers, we'd never hear another word against carbon pricing again. Half our best summer days are gone now to smoke or heat or flood. How many more do we need to lose before we realize that doing our part to curb pollution is the bare minimum required to ensure our economies leave a life worth living behind?
