The Southern Corridor Isn’t Just an Environmental Question — It’s an Economic One
Canada’s protected areas generate $10.9 billion in GDP annually. The Frontenac Arch Biosphere is one of those assets — and there is a calculable cost to degrading it.
The CPAWS white paper Widely Enjoyed but Inadequately Valued (February 2026, peer-reviewed by the C.D. Howe Institute and Simon Fraser University) provides the most comprehensive analysis to date of Canada’s protected areas as economic infrastructure. These are empirically measured returns from assets that require ecological integrity to function.
Protected areas play an outsized role in rural economies, contributing up to 1.6% of rural GDP nationally. Tax revenues from protected areas grew 250% over 15 years — outpacing the 50% growth in public investment. Canada’s protected areas also store the equivalent of emissions from 57.8 billion cars annually, worth $51.1 trillion in avoided global economic damages (CPAWS, 2026).
The Frontenac Arch is an ancient granite ridge connecting the Canadian Shield to the Adirondack Mountains — the only continuous north-south forest corridor in eastern North America. It is home to the highest diversity of reptiles, amphibians, and invertebrates of any national park region in Canada, and holds three formally designated Key Biodiversity Areas (Thousand Islands, Charleston Lake, Frontenac Forests), with the Napanee Limestone Plain proposed as a fourth.
The communities within and around the Biosphere — South Frontenac, Rideau Lakes, Stone Mills, and the broader Frontenac County and Leeds & Grenville areas — support a tourism economy built on what the landscape is: quiet, ecologically intact, dark-sky landscapes. Visitors come to cycle the Cataraqui Trail, paddle the Rideau Lakes, explore Charleston Lake and Frontenac Provincial Parks, and stay in the B&Bs, heritage inns, and agri-tourism operations that depend on these assets.
PM Announcement — March 31, 2026 — Three weeks before the consultation closes
On March 31, 2026, Prime Minister Carney committed $3.8 billion and binding government policy to the following — all directly relevant to the southern corridor:
- Strengthen the protection and recovery of species at risk across Canada to identify priority habitats — the southern corridor crosses confirmed critical habitat for more than a dozen SARA-listed species.
- Leverage regional assessments under the Impact Assessment Act “to proactively address the effects of development on a region before project reviews” — the precise procedural protection communities have requested from ALTO.
- Avoid and minimise environmental impacts using the mitigation hierarchy — a framework requiring demonstration that all less-harmful alternatives have been genuinely assessed before the most damaging option proceeds.
- Implement comprehensive mapping of Key Biodiversity Areas — three designated KBAs lie within the Frontenac Arch; a fourth is pending at the Napanee Limestone Plain.
- Launch an Expert Taskforce on Natural Capital Accounting in spring 2026 to integrate the value of nature into government decision-making — ALTO’s financial model contains no such accounting.
- Commit to 30×30: protect 30% of Canada’s lands and waters by 2030 — the southern corridor crosses thousands of hectares already contributing to this commitment.

International research on HSR and tourism consistently identifies a critical distinction: HSR benefits accrue to communities with stations, not to the landscapes the train passes through. Research on Spanish HSR found that cities with stations saw measurable tourism increases, while communities the train passed through without stopping saw negligible or negative effects as competing destinations became easier to reach. China’s experience shows that HSR promotes tourism in node cities while non-station communities may lose market share.
The southern corridor has no planned station in the Frontenac Arch region. The effect would be to make Ottawa, Peterborough, and Toronto more accessible to each other — potentially drawing visitors away from rural southeastern Ontario — while imposing all construction and operational costs on the communities the line passes through.
MP Scott Reid has confirmed in writing that either HSR corridor option is likely to lead to lower VIA Rail ridership and service cuts through southeastern Ontario. VIA currently provides the region’s primary rail link for visitors arriving without a car. For destinations whose tourism brand is built on environmental responsibility, losing this low-carbon access mode compounds the damage.
The Cataraqui Trail — a 104 km segment of the Trans-Canada Trail used for cycling, hiking, and cross-country skiing — runs directly through the proposed corridor. Trail closures would eliminate itinerary-based cycling tourism and the network of B&Bs, outfitters, and cafés that depend on trail traffic. ALTO has acknowledged its intent to utilise existing corridor infrastructure to reduce land acquisition costs. Dozens of grade separations would require extended closures on secondary roads that are often the only access to farms, cottages, and agri-tourism operations. Noise, dust, and night lighting are fundamentally incompatible with a tourism product built on quiet and dark skies.
A 300 km/h rail line requires continuous fencing across its entire length. Unlike a highway, there are no pedestrian or cyclist crossings. The ecological corridors that define the Frontenac Arch depend on species movement. A permanent barrier fragments habitat, isolates populations of endangered species (Blanding’s Turtles, Grey Ratsnakes, Cerulean Warblers), and reduces the wildlife encounters that drive ecotourism. Loss of ecological integrity could trigger review of the UNESCO Biosphere designation itself — with reputational consequences extending well beyond the physical corridor footprint.
ALTO’s entire environmental case rests on replacing car and air travel with electrified rail. That case is contradicted by routing through the Frontenac Arch. The Biosphere’s intact peatlands, wetlands, and forests function as active carbon storage systems. Fragmenting them converts stored carbon to released carbon, while simultaneously destroying habitat Canada has committed to protect under the Kunming-Montreal Global Biodiversity Framework. A project cannot credibly claim to be green infrastructure while destroying irreplaceable ecological infrastructure to build it.
Every township council along the proposed southern corridor that has voted on the issue has voted against it: South Frontenac Township (unanimous, citing “generational devastation”), Rideau Lakes Township (unanimous), Stone Mills Township (unanimous, calling on ALTO to “remove rural municipal lands from consideration where communities will experience disruption without service benefit”), Tyendinaga Township, and Belleville City Council.
MP Shelby Kramp-Neuman (Hastings–Lennox & Addington–Tyendinaga) formally opposes both routes. MP Scott Reid (Lanark–Frontenac) has stated the project “should be killed” and is sponsoring a House of Commons petition. The Frontenac Arch Biosphere Network has confirmed it was not consulted by ALTO during initial corridor planning — a significant gap given UNESCO’s expectations for infrastructure decisions within biosphere reserves.
Commission a Tourism Economic Impact Assessment
ALTO’s socioeconomic assessments have focused on productivity gains for corridor cities. A dedicated study is required to quantify what construction and permanent operations would cost the rural tourism economy of the Frontenac Arch — using the CPAWS methodology ($3.62 return per $1 invested) to establish the full opportunity cost of degrading this protected area.
Apply natural capital accounting to ALTO’s financial model
The Environmental Assessment must include a protected-area economic valuation. The Prime Minister’s Expert Taskforce on Natural Capital Accounting (spring 2026) is mandated to formalise this methodology. Corridor selection must not outrun the Taskforce’s work.
Confirm that SARA Section 79 notification has occurred
The obligation to notify the competent minister is triggered by current knowledge of likely species and critical habitat impacts — not by the formal start of the environmental assessment. ALTO must confirm and disclose whether this notification has been filed. ALTO’s CEO confirmed on CBC March 25, 2026 that species surveys commenced “this week” — one month before the consultation closes.
Engage Parks Canada, ECCC, and the Frontenac Arch Biosphere Network formally
Parks Canada and ECCC must be formally engaged on the implications for the Rideau Canal UNESCO World Heritage Site and the Frontenac Arch Biosphere Reserve. The Biosphere Network, which was not consulted during initial corridor planning, must be designated a formal consultation stakeholder.
Confirm binding pre-conditions including Trail continuity and VIA Rail services
Pre-conditions must include: continuity of the Trans-Canada Trail (Cataraqui Trail section); wildlife crossing infrastructure through the Frontenac Arch at intervals supporting species movement; and formal assessment of VIA Rail service impacts through southeastern Ontario before route selection is finalised.
Publicly reconcile Bill C-15 with A Force of Nature
The Minister of Transport and the Minister of Environment must jointly confirm, before April 24, whether the IAA regional assessment commitment in A Force of Nature will apply to the ALTO southern corridor — or whether Bill C-15 exemption powers will be used instead. Both cannot apply simultaneously. Communities are entitled to know which governs.
Canada’s protected areas generate $10.9 billion in GDP and return $3.62 for every $1 invested. The Frontenac Arch Biosphere is one of those assets — a rural economy built on ecological integrity, UNESCO recognition, and the character of a quiet, nature-based destination.
International research is consistent: HSR benefits accrue to station communities. The southern corridor has no planned station in the Frontenac Arch region. Communities would bear all construction and operational costs with none of the connectivity benefits.
On March 31, 2026, the Prime Minister committed to regional IAA assessments before project reviews, KBA mapping, and natural capital accounting. The ALTO southern corridor process has not met any of these commitments.
The CPAWS methodology and the government’s own Expert Taskforce on Natural Capital Accounting provide the tools. The calculation has not been done for the Frontenac Arch. It must be — before corridor selection is finalised.
The public consultation deadline is April 24, 2026. Written submissions — specific, factual, and addressed to the issues above — create a formal record that is harder to dismiss than general opposition.
Submitted as part of the ALTO HSR public consultation process. All sources are documented. Research facilitated with AI tools with human review and revision. Consultation closes April 24, 2026.
