TC can say what they like and implying the feds were at fault takes the heat off them from the oil producers in Alberta. Getting these projects through an NEB review means showing that benefits outweigh risks and with $50 oil that's far harder to do than with $100 oil. Replacing some of the environment regulations gutted by Harper is the right thing to do and pushing through a repurposed pipeline proposal simply because you were allowed to put people at greater risk is, frankly, unethical.
