Rich- you're looking out the wrong end of the telescope. The reason the Canadian firms are purchasing the Canadian assets of US firms is that the US is abandoning the Cdn marketplace in search of more business friendly jurisdictions. The foreign oil companies are dumping their assets because of the proposed GHG cap impeding development, enviro nuts, patchwork aboriginal opposition and lack of pipelines to market. So the new Canadian owners you so proudly tout just got sucked in to buy all those problems.
