The mining industry is regulated quite heavily at both the federal and provincial levels. So in the realm of environmental assessments, for example, projects have traditionally been subject to two separate yet in most cases very similar environmental assessment processes, which don't happen concurrently. So a process that could take a year, two years, or more in the past is then repeated for the same duration, thereby prolonging the amount of time it takes for a project to come on line.
Through the changes to the Canadian Environmental Assessment Act, things like equivalency are being introduced.
