Sorry MD...But even if the bidding goes over this threshold and is to be reviewed I really don't think Canada has a choice here. Unless there is potentially a interested Canadian player, which I believe if they exist had best show themselves before the review allows foreign ownership to happen. Yes...Many on home soil seem complacent when you say the words..."Ring of Fire". Our politicians would love for this to just happen on its own without their involvement.  Domestic players or NOT. 

All they are interested in is the political gain that comes from taking the credit from the private sector for giving them the thumbs up, some funding money, and the ole stamp of approval. As long as they get re-elected, jobs are created, the GDP goes up, and the Aussie who owns the Ring agrees to supply the US 1st, and not China, than everything should be peachy. Canada is easy to please.

The whole idea about National Security should have been addressed at the onset of bidding...But it was NOT. Therefore, the price tag can go to the moon for all they care. The issue here IMO lies in the government saying to the winner, "Our blessing for ownership is contingent upon you following our rules we set out...Similar to what Rio Tinto, Vale and Glencore follow while mining in Canada ...Pay your tax, employ Canadians, and support our economy...Thank you." The only time National Security will become an issue is if our neighbors to the South speak in Trudeau's ear about whether an Aussie controlling the Ring poses a threat to them...Which I believe they do NOT. 

So I don't see a review of any sort with trade allies being an issue to limiting the price tag. If a sale happens at any price with these Aussies than obviously National Security issues are not of concern..So neither will going over 1.5 billion to trigger it. If that was the case than the bidding should have stopped long ago if the Ring was so valuable to Canada. How long has it been? 10+  years and counting. We had our chance as a country...We either blew it, or we were waiting for someone to come along. Again, the only problem is Canada wants others to do the work for them. We're too busy politely talking the Ring to death about what we'd like to do, the may ways we could do it, and who we might offend in the process. Such BS...
