Environmental Assessment in Ontario Region

Human activity changes the environment. The significance of these changes is best understood when they are obvious and catastrophic but many are subtle changes that only prove to be important over time. In its roles as advisor and decision maker, Environment Canada assesses a wide range of human activities to ensure their long and short term consequences do not cause irreparable damage to the ecosystem.

Explore this site to learn about the legislative process by which Environment Canada conducts reviews of activities that vary from small environmental enhancement projects to major developments such as oil and gas pipelines, nuclear facilities, mining operations, highways, urban development, landfills and electricity generation. Discover opportunities for participating in the Department’s environmental assessment process and link to relevant legislation, guidelines and environmental assessment reports.


Environmental assessment is a powerful planning tool that provides decision makers with the information they need to ensure the projects they approve are compatible with a healthy, sustainable environment for present and future generations. Environmental assessment is now part of public decision-making at all levels of government in Canada and is used world wide in over 100 countries, in many international organizations and funding agencies and, increasingly, by private business.

At the federal level, environmental assessment is governed by the Canadian Environmental Assessment Act, which obliges the federal government to carefully consider the environmental effects of projects before taking any actions that enable these projects to proceed. The Act promotes sustainable development by ensuring that the proposed works and activities do not cause significant adverse environmental effects within and outside the jurisdictions in which they are carried out. The Act also ensures there is an opportunity for public participation in the assessment process.

Under the Act, Environment Canada is required to conduct environmental assessments of projects for which it has a decision-making role, either as a proponent, a funder, a land manager or, in some cases as a regulator, and we are committed to doing so in an exemplary manner. Environment Canada also plays a strong advisory role by providing its broad science-based expertise on environmental matters to assist other government departments in anticipating, preventing or mitigating adverse environmental effects of projects, and by advocating environmental policies and programs of the Department and the federal government. We also play this advocacy and advisory role outside the federal government through participation in provincial, municipal and aboriginal assessment processes.
