A Council of Canadian Academies report says there are significant health and environmental unknowns in the booming industry and suggests governments should be cautious.
It says 10 years of fracking aren't enough to draw conclusions about its impacts.
David Pryce of the Canadian Association of Petroleum Producers says fracking builds on decades of experience with natural gas.
He says the industry supports the call for more research, but adds industry and governments across Canada are moving quickly to ensure best practices are used.
Pryce says new problems can be addressed as they arise.
Environmental groups say they feel vindicated by the report's findings that concerns about the industry are real.
