RE:Conversion des warrants couples4:
I believe you have answered your question yourself. There CANNOT be a pre-established forex value for conversion ($11.50US) of warrants into shares. You will pay whatever the going conversion rate at the time of your order.
All my shares/warrants etc are still held on NYSE as I have seen little advantage in transfer to TSX, but that is my personal POV.
Keep in mind also that warrants are not tradeable for 30 days after listing.
And given that the Loonie is trading at a high of $82.69 there should be no hurry to convert.
