Conservation Authorities are unique to the province of Ontario. They are local, non-profit environmental organizations that are empowered to regulate
development and activities in or adjacent to river or stream valleys, Great Lakes and inland lakes shorelines, watercourses, hazardous lands and wetlands. The Conservation Authorities Act, passed in 1946, provides the legislative backbone for their
existence. Funding is provided through a combination of municipal and provincial support, permit and service fees and charitable donations.
Toronto and Region Conservation serves a population of more than 4,000,000 people in a jurisdiction that
covers more than 2400 km2. We receive development applications for over 1000 projects per year. These files include engineering and hydrogeologic reports prepared on behalf of the development proponents that often downplay the potential impacts of
their projects to the natural environment. Our role as hydrogeologists is to critically review these reports and determine if reasonable conclusions have been made based on reliable data.
For hydrogeology, we consider both temporary and permanent
dewatering, pre- and post-development water budgets, and consumptive groundwater use. We must then communicate our findings in clear, simple language to our in-house planning team, proponents, and sometimes members of the public. All this is done in
a framework of limited funding and challenging timelines.
We meet these challenges through the use of conceptual and numerical models developed in partnership with neighbouring conservation authorities and our municipal partners. These regional
model results are then shared with development consultants to facilitate continuous improvement from their studies completed at the site scale. To continue to advance our hydrogeologic understanding, we also work with subject matter experts at the
provincial and federal levels of government, and are working at integrating climate change into our models. This presentation will summarize some of our successes and failures over the past 15 years and provide insights to similar organizations
responsible for protecting and enhancing our natural environment.
