What is an Environmental Assessment?

Printer-friendly versionSend by email
Environmental Assessment or EA is a decision-making process used to promote good environmental planning by assessing the potential impacts of certain activities or projects on the environment before construction takes place. In Ontario, environmental impacts can include ecological, social, cultural or economic changes. The EA for the Gardiner Expressway is an “Individual” Environmental Assessment. This process is more detailed than other EAs (referred to as “streamlined” or “class” EAs) and is usually done for very large projects. This process is defined by the Ontario Environmental Assessment Act.
