That's not the injustice. The problem is that Alberta's political interests are very poorly (if at all) represented federally. This has come to a head a few times in the past with things like cancelled pipeline projects or the NEP[1]. So the issue is that Alberta has 11.52% of the population, contributes 15.25% of the GDP, yet must constantly fight against policies that put it at a disadvantage or run counter to its political leanings.

> Estimates have placed Alberta's losses between $50 billion and $100 billion because of the NEP.[32][33] Alberta still initially enjoyed an economic surplus due to high oil prices, but the surplus was heavily reduced by the NEP, which, in turn, stymied many of Lougheed's policies for economic diversification to reduce Alberta's dependence on the cyclical energy industry, such as the Alberta Heritage Savings Trust Fund, and also left the province with an infrastructure deficit. In particular, the Alberta Heritage Fund was meant to save as much of the earnings during high oil prices to act as a "rainy day" cushion if oil prices collapsed because of the cyclical nature of the oil and gas industry.

Cancelled pipeline projects? Ottawa doesn't cancel pipeline projects. All the problems with pipeline projects are caused by environmental reviews etc, which fall under legislation brought in by Stephen Harper, an Albertan.

It's much the opposite, Canada just spent $34B to ensure the Trans-Mountain pipeline got built. Alberta is the one that gets the resource revenue, but it's Ottawa that has to pay for your pipelines. That's hardly fair.

Alberta has one legitimate grievance, the NEP. Which is a plan that was cancelled by Mulroney over 40 years ago.

The AHSTF performed poorly because successive Albertan provincial governments slashed contributions to it, not because of the ghost of the NEP. It was established in 1976, then contributions were cut in half in 1983, and eliminated entirely in 1987. The NEP was gone by 1985.

What hurt Alberta was every cyclical crash in oil prices, and their steadfast refusal to implement additional revenue streams like a provincial sales tax while spending instead of saving their resource-boom surpluses.
