The voting situation was discussed a long time ago, ( I should know as I've been waiting nearly 4 years for it to happen).
AFAIK CUU would have to call a special meeting, file this with SEDAR as a notice of meeting, followed by a Management Information Circular and Form of Proxy.
The fact that EE owns a simple majority of issued shares makes it really a formality as it is his votes that will determine the outcome of the proposal, however to my knowledge by law a publicly owned company requires all shareholders to have their voting rights upheld.
Ah well, back to the lurking in the shadows mode, to all the informative posters such as Prospekt keep up the good work.
