Business focused answers to your environmental, health and safety issues

DLA Piper Canada's Environmental Law practice has a strong presence in all areas of environmental law, ‎including: contaminated lands ‎litigation, ‎defence of environmental prosecutions, real estate and ‎lender transactions with a ‎particular emphasis on ‎brownfields redevelopment, compliance issues, ‎environmental ‎approvals and assessments, due ‎diligence for mergers and acquisitions, waste ‎management ‎and disposal, recycling, waste diversion and ‎recovery, and transportation of dangerous ‎‎goods.‎

Our group of nationally recognized practitioners are involved in some of the most ‎important ‎and ‎‎impactful Canadian and regional environmental matters, as well as cross-border ‎transactions. ‎We ‎have ‎expertise encompassing all areas of environmental law and are ‎at the forefront of delivering ‎innovative ‎solutions to help clients successfully ‎navigate the ‎complexities of a shifting regulatory ‎landscape in ‎Canada. In particular, we have acted on a ‎number of major cross-border transactions ‎involving key ‎environmental aspects.‎

We also have significant involvement with business issues related to corporate social responsibility ‎as local, national and international stakeholders demand environmental stewardship from the ‎individuals and organizations they do business with. To successfully meet these demands, ‎companies and corporations must integrate environmental management into their business strategy ‎and policies. This requires a preventative approach to environmental compliance and liability issues, ‎as well as an understanding of the evolving regulatory landscape. Our group's experience supports ‎this approach.‎

Our Environment group works closely with top professionals in our Corporate, Litigation, Real ‎Estate, Energy, ‎Projects ‎and Indigenous Law Groups to provide comprehensive service to our ‎clients. We have a robust ‎national ‎reputation for our ability to deliver effective, on-the-ground ‎support while also providing ‎access to the ‎vast resources of the DLA Piper global network. This ‎‎unique combination ‎of local knowledge and international reach represents a distinct advantage and ‎‎competitive edge for our ‎clients.‎
