When we began
In 1994, the Canadian Environmental Assessment Agency was established to prepare for the implementation of the Canadian Environmental Assessment Act, 1992 (CEAA 1992), which came into effect in early 1995.
In 2019, the Impact Assessment Act was enacted which created the Impact Assessment Agency of Canada and repealed the Canadian Environmental Assessment Act, 2012.
