Better rules for impact assessments come into effect this month

News release

August 8, 2019 – Ottawa, Ontario - Canadian Environmental Assessment Agency

A strong economy depends on a healthy environment. The Government of Canada is delivering on its promise to put in place better rules for major projects, to protect the environment and communities, advance reconciliation with Indigenous peoples, and ensure good projects can go forward, creating good jobs and economic opportunities for middle-class Canadians.

Today, the Government of Canada announced that the new Impact Assessment Act, the Canadian Energy Regulator Act, the Canadian Navigable Waters Act, and associated regulations will come into force on August 28, 2019. Clear rules for transitioning to the new system are outlined in the legislation.

With hundreds of major resource projects – worth over $635 billion – planned or under construction across Canada over the next 10 years, the better rules outlined in these Acts and regulations are essential to protecting our environment and communities while making sure good projects can get built to create jobs for the middle class.

Better rules will give companies and investors the certainty and clarity they need, and ensure good projects can move forward in a timely way. To support Canada’s competitiveness and attract investment, the new impact assessment system provides clear expectations and shorter legislated timelines, and aims to avoid duplication with other jurisdictions wherever possible with “one project, one review”.

These new rules aim to rebuild public confidence by making federal decisions about projects like mines, pipelines and hydro dams more transparent and ensuring decisions are guided by science, Indigenous knowledge and other evidence. The new approach reflects substantive input from Indigenous peoples, provinces and territories, companies, environmental groups, and the public over the course of three years of engagement.
