The human environment study examines all components of communities and their populations, land use patterns and living environments, as well as the project’s socio‑economic impacts and its effects on quality of life. It also takes into account the expectations, concerns, and values expressed by local populations and community stakeholders through consultation activities, as well as the project’s ’s coherence with local development objectives and visions.

Geophysics is the study of the Earth’s physical characteristics using indirect measurement techniques to determine the physical properties of the subsurface, reveal its structure and composition, and identify the presence of heterogeneities. It relies on non‑destructive methods that provide a continuous and extensive view of the ground, whereas point‑based investigations (boreholes, soundings) offer only localized information.

It has come to our attention that some individuals have received letters or communications falsely claiming to be from Alto. We take these incidents seriously and encourage property owners and the public to remain vigilant.

The Government of Canada is committed to ensuring that the views of Canadians inform the future direction of Alto. Early engagement and outreach to communities and Indigenous Peoples has begun.

Since the beginning of the year, Alto and Cadence teams have completed more than 1,000 field surveys between Ottawa and Montréal.

Geotechnical investigations are carried out to characterize soil, rock, and groundwater conditions along the proposed railway alignment, including areas where infrastructure such as tracks, tunnels, shafts, and other underground structures may be built. They provide essential information to support the design and construction of foundations, earthworks, and underground structures, while ensuring safety, performance, and long-term reliability.

The fish and freshwater mussel studies aim to document and better understand the species present and their habitats. They will describe the types of fish and mussels observed, characterize their habitats, and establish baseline conditions for impact assessment. These studies will enable Alto biologists to better protect these aquatic species and their habitats during the construction and operation of the new railway.
