Irving has been buying more Newfoundland oil since the price of Brent fell to basically the same as WTI.  Oil imports continued to go down in Eastern Canada last year.

Oil imports are going up in the Western provinces, where they now import about 150 thousand bbl/day, mostly diluent from south of the border to thin their heavy oil so it can flow in pipelines.

If Alberta and Sask were really concerned about cutting oil imports, they could cut THEIR imports, buy the diluent that you folks in Nova Scotia are exporting, and ship it 5000 km across the country.

All hat and no cattle.
