I know there are groups that have a vested interest in Canada having only one customer for our oil. Some are in the Middle East and some are South of the border.
The truth is that our oilsands have next to know impact on climate change. Despite Obama's blatant lie that our oil is extraordinarily dirty, California blends are the most carbon intensive in North American. Nigerian is the most carbon intensive in the world. The International Energy Agency has said that all new oilsands production amounts to about 23 hours of C02 emissions from China.
The oilsands are superior to OPEC oil by 4 measures of liberal values: Environmental responsibility, peace, treatment of workers and human rights.
The oilsands are becoming greener all the time with solar panels incorporated in in-situ methods, talingless ponds, a water recycling rate well over 90%. Pulp and paper mills in BC have a greater impact on local environments that oilsands do.
