Project: Canada in a Changing Climate - Ontario Regional Chapter

The Climate Change Impacts and Adaptation Division of Natural Resources Canada is coordinating a national-scale assessment of the state of knowledge on climate change impacts, risks and adaptation in Canada: Canada in a Changing Climate: Advancing our Knowledge for Action.

Over the next four years, a series of authoritative science and knowledge products will be developed that will serve as a resource for Canadians, raising awareness of the key issues facing our country and providing information to support sound adaptation decisions and actions.

As part of Canada in a Changing Climate, the Government of Canada will produce a series of six chapters that address regional priorities for impacts and adaptation. They include: Ontario, British Columbia, Prairies, Quebec, Atlantic Provinces and Northern Canada.

Dr. David Pearson (Laurentian University) and Al Douglas (OCCIAR) will lead the writing of the Ontario Chapter, with support from the Ontario Centre for Climate Impacts and Adaptation Resources (OCCIAR).

On this page, you will find resources and updates of the progress to date on developing the Ontario Chapter of the National Assessment.

Meet the Ontario Regional Chapter Authors

Lead Author

Dr. David Pearson – Professor of Science Communication, Laurentian University.

Dr. Pearson is an earth scientist and member of the Co-operative Freshwater Ecology Unit at Laurentian University. He is a Science Advisor to Science North, where he was the Project Director and then Founding Director from 1980 to 1986. He is currently engaging remote First Nation communities in a two year climate change impact and adaptation study in the far north of Ontario.

From 2001 to 2007 David was Chair of the Ontario Office of the Canadian Climate Impacts and Adaptation Research Network at Laurentian University. He is now science advisor to the Ontario Centre for Climate Impacts and Adaptation Resources (OCCIAR), and was Co-Chair of the Ontario Government's Expert Panel on Climate Change Adaptation. From 2008 to June 2010 David chaired the Science Advisory Panel for Ontario's Far North Initiative.

He has hosted two TV series: "Understanding the Earth" (TV Ontario) and "Down to Earth" (Mid Canada TV); and was the scientist for CBC Northern Ontario's weekly Radio Lab" from 1982 to 1997. In 2000 David received the Geological Association of Canada's Ward Neale Medal for communication of the earth sciences, and in 2003 he was awarded the McNeil Medal of the Royal Society of Canada for public communication of science.


Al Douglas – Director, Ontario Centre for Climate Impacts and Adaptation Resources (OCCIAR).

Al Douglas is the Director of the Ontario Centre for Climate Impacts and Adaptation Resources, located at Laurentian University in Sudbury. He has been working in the field of climate change impacts and adaptation for 15 years and has partnered with many different organizations in Ontario and Canada to develop and deliver adaptation resources and strategies.

Al specializes in facilitating adaptation planning at the local and watershed level and has expertise in climate science; climate change impact, vulnerability and risk assessment; policy development and adaptation planning in natural resource sectors. He has had the privilege of contributing content to 2 Canadian National Assessments of climate change and acted as an expert reviewer for the last 2 Intergovernmental Panel on Climate Change assessment reports. Al is a member of Canada’s Expert Panel on Climate Change Adaptation and Resilience Results.

Canada in a Changing Climate Report (CCCR)

This report is about how and why Canada’s climate has changed and what changes are projected for the future. Led by Environment and Climate Change Canada, this document is the first of the Canada in a Changing Climate: Advancing our Knowledge for Action series and provides the climate-science foundation for upcoming reports, including the Ontario Chapter. It documents changes across Canada in temperature, precipitation, snow, ice, permafrost and freshwater availability as well as in Canada’s three oceans. Click here to read the report.
