via Financial Post - Plans Of Arrangement
An article on plans of arrangement discusses the benefits, including something that might be of direct importance as regards access to capital(not that the company must absolutely depend on raising capital in U.S. markets since the in-substantive defeasment was completed):
"The court approval process ensures fairness to shareholders. That means companies can issue securities in the U.S. on an exempt basis under rule 3(a)(10) of the U.S. Securities Act. Takeover bids do not have the same access to that exemption."
It would seem that an amalgamation under a plan of arrangement would be the course of action taken. It would be important, say if Sprott were looking to add to its Junior miner ETF in the U.S., which is not listed on the TSX. My guess as far as the jurisdiction goes, it woukd be Ontario or under federal jurisdiction that this is all accomplished.
