Open Statement to the Senators of Canada
Re: Safeguarding Freshwater and Natural Heritage in the Context of the ALTO High-Speed Rail Proposal
Honourable Senators,
Watersheds Canada expresses our growing concern regarding the proposed ALTO high-speed rail project connecting Toronto to Quebec, and its potential implications for Canada’s freshwater resources and natural heritage systems.
Across eastern Ontario and beyond, Watersheds Canada works alongside municipalities, conservation authorities, Indigenous partners, landowners, volunteers, and corporate supporters to deliver community-based stewardship programs that protect and restore lakes, rivers, wetlands, and shorelines. These efforts are not theoretical; they are tangible, place-based projects. Hundreds of shoreline naturalizations, erosion control and climate change resilience projects (nature-based solutions), fish habitat restorations, and environmental education initiatives have been funded through a blend of federal, provincial, and municipal investment, alongside private donations, family foundations, and corporate partnerships.
This collective investment has built more than ecological resilience. It has fostered a powerful and growing culture of conservation volunteerism. Individuals and families are actively engaged in safeguarding the health of the very waters that define their communities, economies, and quality of life.
It is within this context that we urge careful scrutiny of the ALTO high-speed rail proposal.
Linear infrastructure of this scale—cutting across watersheds, wetlands, and river systems—poses inherent and significant risks to freshwater health. These risks include, but are not limited to:
- Disruption of hydrological connectivity across watersheds and sub-watersheds
- Increased sedimentation and runoff during construction and operation
- Fragmentation of wetlands and riparian corridors critical for biodiversity
- Long-term impacts on groundwater recharge and surface water quality
- Cumulative stress on already vulnerable aquatic ecosystems
These impacts do not occur in isolation. They directly intersect with, and may undermine, decades of publicly and privately funded stewardship work. The very sites where governments and communities have invested in restoration and protection may be placed at risk by corridor routing decisions, construction practices, or insufficient mitigation measures.
Equally concerning is the potential erosion of public trust and volunteer momentum. When community members see the landscapes they have worked to restore placed in jeopardy, it can diminish confidence in conservation outcomes and weaken the spirit of community engagement that has been so critical to success.
We recognize the importance of modern, efficient transportation infrastructure and the role it can play in economic development and emissions reduction. However such progress must not come at the expense of Canada’s freshwater legacy, particularly in a region as hydrologically complex and ecologically significant as the Great Lakes–St. Lawrence basin.
We respectfully call upon the Senate to:
- Ensure rigorous, transparent, and science-based environmental assessments that fully account for watershed-scale impacts
- Prioritize avoidance of sensitive freshwater systems, wetlands, and previously restored sites in route planning
- Require meaningful consultation with community-based conservation organizations, including Watersheds Canada
- Recognize and account for the cumulative value of stewardship investments already made by governments, donors, and volunteers
- Uphold Canada’s commitments to biodiversity conservation, freshwater protection, and climate resilience
Canada’s freshwater is one of our most defining and vulnerable natural assets. The success of grassroots stewardship efforts demonstrates what is possible when governments, organizations, and community members work together. It is essential that national infrastructure planning reinforces—not reverses—this progress.
We stand ready to collaborate constructively to ensure that both environmental protection and infrastructure advancement can be achieved responsibly.
Respectfully submitted,
Watersheds Canada

I live on the Oakridges Moraine and as a farm that we steward in one of the connecting wildlife corridors, I am very concerned about this project going forward. We sit on some of the best clean drinking water in the world…for now. But each construction project, each new open pit mine for aggregates ..in reality this is what they are…plus the removal of powers to prot3ct the sensitive ecosystems that make up the moraine are all putting pressure on this beautiful resource. It took millions of years to happen. It is taking mere decades to impact and destroy it.
