This is bad news for the Atlantic Provinces and Quebec, for the West,  and for all of Canada.  We need the employment and the oil.  
Note that the Liberals never talk about the environment and safety regarding the number of tanker ships entering our coastal waters and the St. Lawrence to import oil from Russia, US, Africa, Venezuela, and the Middle East, oil that we could be supplying from Alberta. Half of our oil is imported.  All of these countries, except the US, have unsavoury human rights and political policies.
Oil will be used until end of this century.  The Liberals aren’t introducing great measures to enhance green energy use/production.
We need the money from oil for underfunded needs like healthcare and to pay down the massive debt being accumulated.
Trudeau didn’t want the Energy East because he didn’t want to risk his votes in Quebec.  It only required 1500 km pipeline through Southern Quebec and NB, and would have been a much better deal for Canada than Keystone.
