Aves: Rainer, both you and 1 other poster have mentioned this 90% approval for a sale. Where are you getting that from?

Aves, I didn't talk about approval for a sale but approval for a squeeze-out, i.e. forcing remaining shareholders to sell.

I think the 90% threshold is some international standard. In the Canada Business Corporations Act see § 206 (2):

Right to acquire

(2) If within one hundred and twenty days after the date of a take-over bid the bid is accepted by the holders of not less than ninety per cent of the shares of any class of shares to which the take-over bid relates, other than shares held at the date of the take-over bid by or on behalf of the offeror or an affiliate or associate of the offeror, the offeror is entitled, on complying with this section, to acquire the shares held by the dissenting offerees.
