the trudeau government's intent in it's policy - and this was broadcast during the last election campaign - is to act as a public relations arm for the oil industry. not only did the ndp say exactly the same thing, but they were actually more aggressive about it. while carrying through with certain environmental actions may be seen as bettering the public perception of the oil industry, the primary focus was always to act in the best interests of the oil sector.

so, that is the answer to your contradiction - it seems incoherent on it's face, but only until you realize what they're actually doing.
