Environmental Compliance Approval (ECA), formally known as a Certificate of Approval prior to October 31, 2011,  are permits issued by the Ontario Ministry of Environment under the Environmental Protection Act, that allow the discharge of air, water, and noise, generated as a result of various industrial processes.  These approvals are designed to ensure that no regulated facility or process is adversely affecting the surrounding environment.


ECOH has been guiding proponents through the Certificate of Approval process for several years.
