When Ontario Regulation 1/17 came into effect in 2017, businesses that install new equipment or modify existing sources which emit contaminants into the air generally have to apply for an Environmental Compliance Approval (ECA) or have to register the activity on the Environmental Activity and Sector (EASR) Registry for the Ministry of the Environment, Conservation and Parks.


OSB Consulting has over 30 years experience of completing Environmental Compliance Approval (formerly Certificate of Approval (C of A)) application for our clients.   Our clients range from small local manufacturers, to large major businesses in the food, alcoholic beverage, coffee and tea making as well as the paper and printing industry.
