Guide

Quebec land and environment profile

Explore official Quebec and Canadian datasets for zoning, elevation, soils, groundwater, contaminated sites, building exposure, Nunavik permafrost and federal environmental projects.

This page groups official public-data sources useful for understanding the context around land in Quebec. Nearby records are context, not a diagnosis of a specific property.

Agricultural zone and CPTAQ

The agricultural zone plus registered inclusion and exclusion decisions.

Public-land leases and land rights

Leases on Quebec public land for different uses.

Watersheds

Multi-scale hydrographic basins and drainage areas.

Elevation, slope and LiDAR

NRCan HRDEM terrain/surface models through official services without mirroring massive rasters.

Soils and plant hardiness

Soil landscapes, texture, drainage and plant hardiness zones.

Geotechnical investigations

MTMD investigations, boreholes and stratigraphic information.

Groundwater

RSESQ monitoring, SIH wells and PACES regional resources.

Building exposure and land hazards

Canada Structures adds Quebec building footprints as an exposure layer to combine with hazards. The large GeoPackage remains hosted by Public Safety Canada.

Nunavik permafrost

TTOP mapping of continuous, discontinuous and sporadic permafrost plus isolated patches north of the 55th parallel. Regional context only; construction requires site-specific geotechnical investigation.

Radon

Regional context; a building must be tested directly to know its level.

Earthquakes

Official historical archive filtered to Quebec and recent activity.

Biodiversity

Invasive and at-risk species, filtered GBIF observations and regulated plant-pest areas.

Contaminated sites

Quebec MELCCFP records and the Federal Contaminated Sites Inventory, kept separate by jurisdiction.

Federal projects and authorizations

Use the Fisheries Act Registry complement and federal Common Project Search to locate published authorizations or projects in an area.

Important: Atlas provides public-data context and source discovery; professional studies, CPTAQ decisions and required regulatory checks remain separate.
