Canada is rich in natural resources. Developed responsibly, these resources create good jobs and support strong communities and our high quality of life.

Major projects worth billions of dollars are planned across the country.

Hydro electric dams, pipelines, offshore oil and gas wells, marine shipping terminals, roads and mines—projects like these help keep Canada prosperous.

But without impact assessments, development can have serious negative effects on the environment and the way of life in nearby communities.

Before a major project begins, the Government of Canada consults with companies, experts, other governments, indigenous groups and local communities. The goal is to maximize the project's positive impacts and minimize any negative ones. The process is led by the Impact Assessment Agency of Canada.

Our job is to consider what people have to say about how major projects may be developed.

Not only do we lead on the assessment of environmental impacts…

But also economic impacts … socio-cultural impacts …

and health impacts.

We also ensure that when the federal government approves a project, the company complies with any of the conditions of approval.

Our work is guided by five principles:

Fostering reconciliation and partnership with Indigenous peoples.

Cooperating closely with other jurisdictions to achieve "one-project, one-assessment."

Basing decisions on scientific evidence and Indigenous knowledge.

Providing predictability, transparency and timeliness for proponents and investors.

And engaging meaningfully with the public—ensuring that everyone has their say.
