Oppose the renewal of Dofasco's permit to exceed Ontario's standard limits on air and noise pollution!
March 6, 2026
The Ministry of the Environment has posted a notice on the Environmental Registry of Ontario (ERO) for the public to comment on a proposal to renew Dofasco’s permit for Limited Operational Flexibility (LOF) to exceed Ontario’s standard limits on air and noise pollution.
Hamilton 350 has made this short explainer video to break down the key issues with the current proposal and encourage all concerned Hamilton residents to submit their comments with some very important and achievable demands.
- We need more public transparency on pollution limits and timelines for the permit, taking into account the total cumulative air pollution by all industry in Hamilton.
- We require continuous monitoring for benzene and the implementation of fenceline monitoring around the site.
Our video also shows you how to comment online, it’s quick and easy!
Take action! Submit your comments to the ERO.
Please take a few minutes to write your own personal comments: how are you impacted by air and noise pollution, why are you concerned, and the improvements to this plan that you want to see before any pollution permits get renewed.
The submission deadline is Thursday, March 12.
