Established in 1991, ONEIA is the business association representing the interests of the environment industry in Ontario. Our network of thousands of contacts includes key people at environmental technology, product and service companies, law, investment and insurance firms, institutes, universities and governments.


Join us for Environment Industry Day 2015

Registration is now open for our annual day at the Ontario Legislature on Tuesday, October 20th.
Each year, representatives from a range of ONEIA companies gather at Queen’s Park to talk about the concerns of our industry with politicians and policymakers.  We all know that smart legislation and regulation is an important driver for our businesses – just as measures that are not well-thought out can be a business killer. 

EID is our way to ensure that politicians hear about the tremendous potential of our industry and our need for a progressive legislative and regulatory environment. READ MORE and REGISTER

ONEIA shares concerns with City of Toronto on Brownfields 

ONEIA’s active Brownfields Committee continued to work on behalf of our members in this key issue, meeting with representatives of the city of Toronto late in 2014 to share or concerns about changes to its policies regarding how “contaminated lands” are conveyed to the City. 

The group followed up its meeting with a letter outlining our position, noting that while the new policy is making progress, more work needs to be done .  To read a copy of the letter, click here.
