i would think there'd be some basis...not familiar with the CAN to CAN business laws and how they relate to the bi-lateral investment treaty or international law..but maybe...

tortious interferance (direct adverse affect on share price through the use of media reporting statements from rusoro which to date remain baseless and unfounded according to venezuela) ?

lible (spelling)? the statements about coupsters in kry management making a permit to kry an impossibility?

maybe insider trading/info fraud laws if rusoro is aware of a situation that no one else is....

in any case i would think the CAN government would be a little miffed at rusoro for stirring up this shi+storm.....
