Environmental law and the regulation of environmental issues that impact on everyone having any kind of contact with the environment is a constant concern.  It requires careful attention to the issues and the assistance of experienced, knowledgeable counsel with a demonstrated background in dealing with these matters.  The environmental law team at Mann Lawyers has the knowledge and experience necessary to help owners navigate this challenging legal arena.

At Mann Lawyers, our environmental lawyers are exceptionally skilled in dealing with all aspects of environmental law, from ligation to regulatory matters to orders issued by the Ontario Ministry of the Environment, Conservation and Parks and the federal Ministry of the Environment and Climate Change.  Our clients can have confidence that they have chosen lawyers who are not only remarkably well-qualified, but who also understand all of the issues, risk and challenges that may arise when dealing with environmental matters.

The field of environmental law is constantly growing and evolving and our environmental lawyers are at the forefront of the field, having been involved in several precedent setting decisions over the past 20 years.
