Mark Mattson: WaterKeeper

The nature of water is that it should be clean, drinkable, accessible, fishable, swimmable.
– Mark Mattson


Mark Mattson has used his background in criminal law to successfully run Lake Ontario Waterkeepers since 2001. Their goal is to promote “Swimable, drinkable and fishable water”. Since then, he has gained a reputation as a dedicated environmental warrior who aims to bring meaning and force to environmental laws everywhere.

Mark is also the proud founder of the volunteer-based Environmental Bureau of Investigation, dedicated to identifying and prosecuting environmental offenders.

He is a great example of how any skill set, coupled with the right amount of passion and dedication, can be used to help the environment and make a real difference. Mark works in conjunction with others who use their skills to raise environmental awareness and provoke action. He has worked with some of our own Green Heroes eco-artists such as Bruce CockburnSarah Harmer and Gord Downie. Mark has also worked with hit-maker Broken Social Scene along with many more well-known names through Waterkeeper’s Swim, Drink, Fish Music project.
