Huge differences from the get-go.
One example is that Norway's resource is off-shore. The cost of building an offshore platform is very high, however, you can drill dozens of wells from that one source once in place... Not so with resopect to land-based extraction
.. But that is an aside. Canada is a different nation, with a different system and a different economy.
Honestly, if you wish to select energy as the commodity to nationalize, why stop there? There is forestry, manufacturing, financial services, fast-food, mining, etc, etc.
You can assess the historical successes of those nations that took that road... It ain't pretty
By the way, this fantsay about the taxpayer 'propping-up' the industry is horse sh*t.
Really, do just a tiny bit of research and it will be clear that this is no where near the case, except in the minds of WWF'ers and Greenpeace'ers
