In Ontario, everyone has an interest in, and indeed, the right to speak up for matters impacting the fundamentals of life: air, soil, water and wildlife. These rights are protected under the Environmental Bill of Rights, 1993 which obligates the Ontario government to consult the public on matters of environmental significance using a platform called the Environmental Registry of Ontario (ERO).
Public participation in environmental decision making is a necessary exercise in democracy and transparency, particularly in an era when the provincial government is scrapping protections for the most vulnerable wildlife and habitats despite living in a global biodiversity crisis. Exercising your rights to consult on these matters and provide your input to the government is more important than ever.
The ERO acts as the main “hub” where the Ontario government gives the public notice on proposed changes to, or when creating new, environmental acts, regulations, policies or instruments. Most notices go through public consultation and follow three main stages:
When notices are in the proposal stage, it is important to read the details carefully to consider the range of impacts that may occur based on what is being proposed. The public is then given a minimum of 30 days to provide comments.
A notable example of this includes Bill 5, also known as Protecting Ontario by Unleashing Our Economy Act, 2025, which contains the government’s plans to replace the Endangered Species Act, 2007 with a performative and significantly weakened Species Conservation Act.
Here are five simple steps to add your comments to ERO postings:

Once the comment period is over, the government will begin its review stage, including a review of each comment submitted on the portal. Though participation does not count as a “vote” to be tallied, the more voices there are to speak up for the environment, the more likely the government is to take notice. Regardless, they must consider all relevant comments when making their decision.
When the government has made their decision, they will post a summary of the decision on the relevant ERO notice, including how they considered public input and whether there is an appeal process.
Ontario Nature regularly participates in the ERO consultation process to advocate for strong environmental policy and legislation.
