Profiles of CELA's Casework


CELA counsel provide representation in the courts and before tribunals on matters of environmental law to Ontario residents and community groups who qualify for legal aid. Illustrative examples of some (but not all) of our cases are profiled on our website via the links below.

As one of several specialty legal aid clinics in Ontario, CELA counsel provide additional service to the public through advice and guidance to other clinics, private bar lawyers, MPPs, and community agencies in our specialized areas of law. All of CELA’s legal services are capacity-dependent and guided by case selection criteria.
