Ontario's Environmental Activity and Sector Registry (EASR) was designed to provide a streamlined alternative to the Environmental Compliance Approval (ECA) process for eligible lower-risk facilities and activities. For many organizations, EASR can significantly reduce approval timelines while maintaining environmental protection requirements.

If your business releases pollutants into the air or land, you must get approval from the Ministry of the Environment, Conservation and Parks (MECP). These approvals ensure your activities do not harm the environment or people. Requirements vary by business type and fall into three categories: Environmental Compliance Approval (ECA), Environmental Activity and Sector Registry (EASR), and Renewable Energy Approval.
