Contaminated sites: the Canadian situation in an international context

Over the last 2 decades, policy-makers have been giving increasing attention to the remediation and redevelopment of contaminated sites, especially those located in urban areas commonly referred to as brownfields. Traditionally, private developers have tended to ignore these sites on account of a series of obstacles of a structural-political nature, including variability in regulatory processes, lack of information on soil quality, impractical clean up standards, fear of liability, and limited funding resources for clean ups. This paper examines the types of policy-making measures that are currently being taken in Canada to overcome these obstacles, comparing them to those being taken in the US and Europe. It is argued that the contaminated site-related policies and programs employed to overcome each obstacle, both within Canada and internationally, are converging in style and content as governments are becoming more aware of the types of costs and risks they must share in order to solve the problem effectively. It is also argued that this trend is unfolding in a relatively predictable way, and that policy-making in Canada is evolving more slowly than it is in the other jurisdictions examined.
