Thank you for your insights, Kinte.

The HuffingtonPost has written an article on what miner's can expect from the new government. This is what they have to say about legislation:

Perhaps the biggest change that mine developers will see with the new government is the Liberals' determination to reverse the Conservatives' streamlining of environmental approvals by skipping the federal approval process, if the project had already met environmental approvals at the provincial level.

The Conservatives saw the two-stage approval process as an expensive and time-consuming duplication of effort, while the Liberals and NDP saw it as necessary oversight, with the federal government not being subject to the more parochial political pressures sometimes applied to provincial regulators.

I don't think it would take long to reverse this particular legislation but we have already applied under the old rules which is the same. I was hoping Teck would cancel that application and re-apply under the streamlined process, but I had no indication they were thinking about this.
