This is what happens when a bunch of politicians try to pick 'economic winners', heavily influenced by industry insiders. Pick bitumen sands as a politically anointed and subsidized industry?  Politicians make impossible promises to win a popularity contest every four years.  None of them can explain the difference between conventional oil refining, and its relationship to the 'inverse process' know as tar sands upgrading, which is more costly.  In conventional oil processing, crude oil is altered through distillation processes to make fuels, lubricating oils, petrochemicals, pipeline quality gas natural gas, and the final by-product is asphalt or bitumen. Upgrading of bitumen extracted from bitumen sands (in Alberta, Saskatchewan) relies on the availability of diluents or condensates obtained only from conventional processing to make the sticky bitumen 'flow'.  Who produces & sells diluents? There is an increasingly costly limit there. Can politicians identify it? Not likely.
