"So, how will shareholders benefit from all of this?"
Those who have an average price lower than the expected deal range of $6 to $7 stand to make a profit; while those with a higher cost base will be well served to average down at current levels ahead of the deal. There is also a possibility that they may divest only the Canadian assets and turn the rest into a trust, this should lead to a higher share price and a dividend stream.
