This makes absolutely no sense.  

For example:  The fact that Irving in NB imports oil while Newfoundland exports oil does not change Newfoundland's bottom line as they sell the same amount of oil either way.  Same goes for all the other oil producing provinces.

Should Irving buy Newfoundland's oil?  Not if they can get oil cheaper elsewhere.  If they paid a premium for oil just because it's Canadian, that would simply increase fuel costs and harm the economy -- while having no economic benefit.

Similarly, it makes no sense for Newfoundland to sell Irving oil for cheap if they can get a better price from the Yanks and the Brits.

If somebody can rationally explain the benefits of so-called "oil security" I'm all ears.  But as far as I can see, there's no economic benefit in waving the flag.
