The 2023-2027 Lake Ontario Lakewide Action and Management Plan (LAMP) is a binational, five-year ecosystem-based strategy to restore and protect Lake Ontario water quality.
 

The Lake Ontario LAMP fulfills the United States of America (U.S.) and Canadian commitments under the 2012 Great Lakes Water Quality Agreement (GLWQA, 2012) by assessing ecosystem conditions, identifying environmental threats, setting research and monitoring priorities, and determining further actions for governments and the public.
 

The LAMP is a model for cooperation among governmental jurisdictions and their management agencies and a resource for anyone interested in the Lake Ontario basin ecosystem, its water quality, and actions to protect this extraordinary Great Lake.
 

Coordination is undertaken by a binational Working Group, supported by technical work groups, science committees, and coordination teams focused on key themes such as water quality, habitat and species, coastal resilience, and public engagement. These teams coordinate efforts to engage stakeholders to identify priorities for the assessment of current and future potential threats to water quality, and for the identification of priorities to support actions. The Saint Regis Mohawk Tribe (SRMT) Remediation and Restoration (R&R) Program is part of the Lake Ontario Partnership Working Group (LOPWG). Members of the public are essential to the development and implementation of the Lake Ontario LAMP.
 

Indigenous knowledge—complex, place-based knowledge systems rooted in the worldviews and laws of Indian Nations, First Nations, and Métis—plays an essential role in understanding and caring for Lake Ontario. Traditional Ecological Knowledge (TEK), as one expression of these systems, offers detailed insights into environmental change, species, and relationships among water, land, and all beings. TEK is an independent and sovereign knowledge system that may only be shared at the discretion of Indigenous knowledge holders and in accordance with their protocols.
 

The Lake Ontario Partnership recognizes the importance of Indigenous-led stewardship and co-development of science and actions under the LAMP. Indigenous governments and organizations help assess lake status, identify priorities, and shape management actions, including through ongoing work under the GLWQA to support better and respectful engagement of TEK and Indigenous knowledge in Great Lakes research, monitoring, and decision making.
 

Indigenous Peoples First Nations and Indian Nations have deep, longstanding relationships with Lake Ontario, grounded in thousands of years of stewardship, use, governance, and responsibility in relation to the basin's lands and waters. The Lake and its tributaries have sustained communities with food, medicines, transportation routes, and places for ceremony, governance, and trade.
 

The name “Ontario” itself is derived from the Mohawk word “Oniatarí:io,” often translated as “Beautiful Lake,” and Toronto from “Tkaronto,” “the place in the water where the trees are standing,” reflecting the central role of these waters in Indigenous life and languages.

Today, the Lake Ontario basin remains home to Indigenous communities of diverse nations and groups, including Anishinaabe, Haudenosaunee, and Métis peoples. Their inherent rights, Treaty Rights, laws, and governance systems continue to shape how they care for the lake and its tributaries. Access to healthy waters, wetlands, fisheries, and shorelines is vital for cultural continuity, harvesting, ceremony, and community well-being.
