Guidance on submitting geospatial data

June 8, 2020

Table of Contents


Under section 6 of the Information and Management of Time Limits Regulations, any information that is required to be submitted by a proponent under the Impact Assessment Act must be in a machine-readable format.

The Impact Assessment Agency of Canada (IAAC) requires proponents to provide electronic geospatial data files for site maps provided in the Detailed Project Description. Additionally, geospatial data files may be required in the Tailored Impact Statement Guidelines issued to proponents at the end of the planning phase. These files are to be submitted along with the Impact Statement. The following document provides guidance on submitting electronic geospatial data files to IAAC during the impact assessment process.

What should be submitted?

Detailed Project Description

Proponents are required to submit electronic geospatial data files for the site maps detailing the project’s proposed general location and the spatial relationship of the project components, which were included in the Detailed Project Description.

This would include (where applicable) geospatial data showing:

The geospatial data must include any options that the proponent is considering, in relation to proposed location, routes or components.

For linear projects under the Canadian Energy Regulator Act, the proponent may provide information on the specific proposed route, or on the corridor within which a specific right-of-way will be determined at a later date.

Proponents are not required to submit the electronic geospatial data files for background layers from publicly available sources that show, for example:

Proponents may, however, choose to provide this additional information to IAAC, for release to the public, under the terms of the Open Government Licence – Canada.

Impact Statement

Proponents must provide any geospatial data files that are required in the Tailored Impact Statement Guidelines (TISGs) for the project, which may include:

If the TISGs require submission of other data types not covered in this guidance (e.g. non-geospatial data file or database, analytical script or workflow), please contact IAAC’s regional office in your area for more guidance.

Submission requirements

Proponents are required to provide site maps to IAAC as electronic geospatial data file(s). This would include:

Proponents are strongly encouraged to make data available in one of the following data projections:

Proponents are strongly encouraged to select a projection that is best suited to the geographic region and / or scale of the dataset. Please note the Web Mercator WGS84 projection is not suitable for areas in the far North (e.g. north of the 60th parallel).
