"No review is needed because it is not likely to be needed". This circular argument was written by Minister of Natural Resources Joe Oliver in response to complaint about no public review of the Northern Graphite mine at Bissett Creek on the Northeast border of Algonquin Park in Ontario. 
Proposed mines must submit a Closure Plan open to 30 day public review, after which they get their go ahead. The Ministry of Natural resources refuses to make public copies easily available to the public on their website along with the public notice. In this case a paper copy was available during 20 days of business hours in Sudbury.
Lacking in this and possibly all closure plans is a mention of cost, how funds will be accumulated over the life of the mine, and designation of a neutral party to hold the money (bond) for closure only. The Kearney mine on the other side of Algonquin is an environmental open wound.
The final sadness is we export jobs when we buy back semi-raw resources as finished goods.
