CLOCA's Conservation Areas Map



Central Lake Ontario Conservation (CLOCA) is a local, community-based, environmental organization and one of 36 Conservation Authorities responsible for managing watershed resources across Ontario. Established in 1958, CLOCA's jurisdiction is based on the watershed boundaries of 4 major watercourses and 18 minor watercourses draining an area of over 639 square km.  Our watershed stretches from the municipal boundaries of Ajax/Pickering to Clarington, and north, from Lake Ontario to the crest of the Oak Ridges Moraine (see map below).  

We provide a wide variety of science-based watershed management programs and services, delivered in partnership with our municipal partners, local landowners, environmental agencies and all levels of government.  Our municipal partners include the Region of Durham, Cities of Oshawa and Pickering, Towns of Ajax and Whitby, Municipality of Clarington and Townships of Scugog and Uxbridge.

Administration Office

CLOCA's Administration Office was once the location of scythe and farm machinery manufacturing and later Robson's Tannery which provided footwear to Canada's Armed Forces in the Second World War.  It was designated as a 'property of cultural heritage value or interest' by the City of Oshawa in 2019. A historical visual animation can be viewed below.

Strategic Plan

The process to update our Strategic Plan 2021–2025 included a variety of consultation sessions, through online meetings and surveys, to provide additional insight, new ideas and feedback on what worked and what needed to change.


We sought input to determine where we should make improvements to our services and programs, what’s most and least important to our audiences in our current roles and responsibilities, and what challenges and opportunities we are likely to face in the future.
