Environment and Climate Change Canada - ECCC

Monitoring the St. Lawrence
One of the roles of Environment and Climate Change Canada is to study the St. Lawrence from various angles in order to inform the public and decision-makers on the state of health of that gigantic ecosystem. Water quality, sediment contamination and the evolution of bird populations are just a few examples of indicators used for this purpose. Whether in the field, in a laboratory, or in their offices, Environment and Climate Change Canada scientists gather and analyze a wide range of information to better understand the past, present and future of the St. Lawrence.


Researching the St. Lawrence
Researchers at Environment and Climate Change Canada try to better understand the problems, known or emerging, that face the St. Lawrence. For example, Environment and Climate Change Canada examines the effects of pharmaceutical substances contained in urban waste water on aquatic organisms.


Mobilizing for the St. Lawrence
Many residents and organizations are involved in maintaining the health of the St. Lawrence. Through funding programs like the Community Interaction Program or EcoAction, Environment and Climate Change Canada supports communities in carrying out restoration, awareness and conservation projects.


Managing the St. Lawrence
The St. Lawrence ecosystem is rich and diverse. Urban areas and wilderness overlap, and the diverging interests of its many inhabitants can sometimes conflict. It is therefore important to ensure collaborative management of the St. Lawrence. To that end, Environment and Climate Change Canada is, among other things, part of the International Joint Commission, an independent organization through which Canada and the United States work together to manage boundary waters, including the St. Lawrence.

La gestion de la faune aquatique au Québec
Chaque année, des techniciens de la faune et des biologistes du ministère des Forêts, de la Faune et des Parcs (anciennement le ministère du Développement durable, de l'Environnement, de la Faune et des Parcs) parcourent les lacs et rivières du Québec afin d'inventorier les populations de poissons. Ces données précieuses permettent au Ministère d'établir l'état de santé des communautés de poissons et d'adapter les modalités d'exploitation de la pêche sportive et commerciale. Cette vidéo présente un aperçu des travaux effectués dans différentes régions du Québec.

Charting the seabed for your safety; the role of the hydrographer
The Canadian Hydrographic Service conducts surveys and produces official marine charts that describe Canadian waterways. These charts indicate depths, identify hazards and describe the positions of aids to navigation to determine safe passages, avoid disasters and protect the marine environment.


Canadian Coast Guard - The Sounds of Icebreaking
The underwater sound of the bubbler system on the Canadian Coast Guard Icebreaker CCGS Henry Larsen. Compressed air from under the hull pushes ice away from the ship and reduces friction on the hull.


Research on the survival of wolves outside the water
In eastern Canada, wolffish and spotted wolffish are at risk. Research has shown that wolves can survive up to two hours out of the water. The mandatory catch and release of these wolves in bycatch contributes to their recovery, even when stay long in fishing gear.
