The Impact Assessment Agency of Canada (IAAC) announced today that the Minister of the Environment, Climate Change and Nature has determined that the Timiskaming Dam-Bridge of Quebec Replacement Project is not likely to cause significant adverse environmental effects under the Canadian Environmental Assessment Act, 2012 (CEAA 2012), taking into account the implementation of mitigation measures and the inclusion of legally binding conditions that the proponent must comply with. This ministerial decision is grounded in the conclusions of the environmental assessment report for the project prepared by IAAC.

The project, which consists of a bridge spanning the Ottawa River and linking the provinces of Ontario and Quebec, has been subject to a rigorous federal review based on scientific evidence and Indigenous knowledge. Public Services and Procurement Canada (the proponent) will construct a new modern structure, consisting of two lanes of traffic and a sidewalk, to regulate water levels on the river and provide a vital transportation link between the two provinces, while supporting local employment and the proponent's collaboration with Indigenous Peoples during construction.
