The concept of a statutory review of the act's performance after five years was not entertained due to a number of limitations and drawbacks inherent in such a process.
In Nunavut in particular, within the first five years of the act's existence, there may only be a few major projects that are subject to environmental assessment. This would be a very limited sample size from which to draw any meaningful conclusions.
In addition, such reviews often consume more resources, both financial and human, than are saved by any marginal improvements resulting from what can turn out to be a lengthy process.
