The Council of Canadian Academies


Science Advice in the Public Interest


The Council of Canadian Academies (the Council) is an independent, not-for-


profit organization that supports independent, science-based, authoritative expert


assessments to inform public policy development in Canada. Led by a 12-member


Board of Governors and advised by a 16-member Scientific Advisory Committee,


the Council’s work encompasses a broad definition of science, incorporating the


natural, social, and health sciences as well as engineering and the humanities.


Council assessments are conducted by independent, multidisciplinary panels of


experts from across Canada and abroad. Assessments strive to identify emerging


issues, gaps in knowledge, Canadian strengths, and international trends and


practices. Upon completion, assessments provide government decision-makers,


researchers, and stakeholders with high-quality information required to develop


informed and innovative public policy.


All Council assessments undergo a formal report review and are published and


made available to the public free of charge in English and French. Assessments


can be referred to the Council by foundations, non-governmental organizations,


the private sector, or any level of government.


The Council is also supported by its three founding Member Academies:


The Royal Society of Canada (RSC) is the senior national body of distinguished


Canadian scholars, artists, and scientists. The primary objective of the RSC is


to promote learning and research in the arts and sciences. The RSC consists


of nearly 2,000 Fellows — men and women who are selected by their peers


for outstanding contributions to the natural and social sciences, the arts, and


the humanities. The RSC exists to recognize academic excellence, to advise


governments and organizations, and to promote Canadian culture.


The Canadian Academy of Engineering (CAE) is the national institution


through which Canada’s most distinguished and experienced engineers provide


strategic advice on matters of critical importance to Canada. The Academy


is an independent, self-governing, and non-profit organization established


in 1987. Fellows are nominated and elected by their peers in recognition of


their distinguished achievements and career -long service to the engineering


profession. Fellows of the Academy, who number approximately 600, are


committed to ensuring that Canada’s engineering expertise is applied to the


benefit of all Canadians. iv Environmental Impacts of Shale Gas Extraction in Canada


The Canadian Academy of Health Sciences (CAHS) recognizes individuals of


great achievement in the academic health sciences in Canada. Founded in 2004,


CAHS has approximately 400 Fellows and appoints new Fellows on an annual


basis. The organization is managed by a voluntary Board of Directors and a


Board Executive. The main function of CAHS is to provide timely, informed,


and unbiased assessments of urgent issues affecting the health of Canadians. The


Academy also monitors global health-related events to enhance Canada’s state


of readiness for the future, and provides a Canadian voice for health sciences


internationally. CAHS provides a collective, authoritative, multidisciplinary


voice on behalf of the health sciences community.

Message from the President


The development of unconventional oil and gas resources — including shale


gas — holds prospects for dramatically changing the global energy supply.


Jurisdictions worldwide are weighing the potential benefits and impacts of this


development. As the world’s third-largest natural gas producer, fourth-largest


exporter, and possessing vast shale gas resources of its own, Canada has a major


stake in this new source of energy.


The Council of Canadian Academies was asked by the federal Minister of


Environment to assemble an expert panel to assess the state of knowledge about


the impacts of shale gas exploration, extraction, and development in Canada.


In response, the Council recruited a multidisciplinary panel of experts from


Canada and the United States to conduct an evidence-based and authoritative


assessment supported by relevant and credible peer reviewed research. As with


all Council panels, members were selected for their experience and knowledge,


not to represent any particular stakeholder group. The report does not include


recommendations, since policy prescription falls outside the Council’s mandate.


This report and its findings come early in the conversation about the development


of Canada’s shale gas resources. Council assessments strive for consensus, which


proved challenging in this case given the number of issues involved, the lack


of evidence on some of those issues, and rapidly evolving industry practices.


While this report is far from the last word on this topic, the Council believes


the Panel has shed light on important matters that need further reflection.


The report focuses on Canada as a whole but points to significant regional


characteristics and differences wherever these are relevant. It is the Council’s


hope that everyone engaged in and concerned about this topic will find value


in the Panel’s assessment. The Council believes that this report can inform both


public discussions and a future environmental research agenda on a natural


resource that could play an important role in the future of several provinces.


The Council is deeply appreciative of the contributions and assistance it received


from numerous individuals and organizations throughout the course of its work.


First and foremost the Council thanks the Expert Panel members who gave


generously of their time and expertise for this challenging assessment, as well


as the peer reviewers who commented on a draft of the report. The Council is


grateful to Mark D. Zoback, Professor of Geophysics, Stanford University, and


to Jennifer Miskimins, Associate Professor, Petroleum Engineering Department, viii Environmental Impacts of Shale Gas Extraction in Canada


Colorado School of Mines, for their insight and counsel throughout the


assessment. The Council also wishes to acknowledge the many other individuals


and organizations that provided helpful advice throughout this assessment.
