In Alberta, this would apply. "The threshold for shareholder consent for a takeover bid is 90%, per part 16 of the Business Corporations Act, RSA 2000 c. B-9."

It is not 2/3. The offeror requires 90% approval of shareholders for a takeover. 

So to take your example (as I understand it) should Eastern sell to HL, that would give HL approx 50-55%+. Then HL would need 90% approval from the remaining shareholders which may be difficult to get unless HL makes a valid buy out offer. 

I'll go along with a $10 per share and (WT & WT.A) warrants. haha!

IMO....Koo
