What independence could mean for oil-rich Alberta's economy

For Alberta independence supporter Keith Wilson, the western Canadian province is in a league of its own.

With its wealth of rich oil and gas reserves, a significant agricultural sector and a young and skilled workforce, its economy is one to be reckoned with, says Wilson.

The province will hold a referendum on 19 October, giving residents two options: vote to stay in Canada, or vote to move ahead with a formal binding referendum on independence at a later date.

The vote, despite not being a cut and dry "stay or leave", still stands to be among the most consequential in recent Canadian history, and a significant test of national unity.

One key issue has become central to the debate: Would Alberta be richer if it were to become an independent country?

The answer for Wilson is yes.

"Alberta's economy is unique. is fundamentally different than the rest of Canada's - we have the people, the institutions, the infrastructure to excel," he says.

Alberta separatists have long argued that the province has been short-changed by being part of Canada, and that more of the oil and gas wealth would be kept within its borders instead of being shared with Ottawa, delivering it tens of billions in savings.

But many disagree with their accounting.

Alberta Premier Danielle Smith, who opposes independence, predicts a more sober outcome. She says the province could risk paying C$400bn ($283bn; £213bn) in transition costs alone, while bleeding billions more in lost investments and trade due to the political upheaval.

A report commissioned, external by her government released earlier this month calculated the costs of separation as between C$50bn and C$170bn over five years - and a highly unpredictable outlook over the long term.

The report cautions that the to-do list for a newly independent Alberta would be long and costly.

It would have to set up agencies to manage taxes and national security, develop its own constitution, legal and court systems, and pension plans, and negotiate the division of federal assets like national parks and military bases.

Lennie Kaplan, a former finance official in Alberta, says the province would be expected to take on a share of Canada's national debt, among many other fiscal challenges and responsibilities.

A report on Alberta independence by the CanadaWest Foundation, external, a non-profit Alberta-based think tank, estimates that the province could be stuck with additional debt ranging from C$258bn to C$333bn.

With a projected hit to Alberta's GDP and the additional costs, the report estimates separation could hit Albertans' bottom line and reduce their disposable income by 5.8% on average.

"Why do we have to create all this uncertainty that might impact and impair the province's fiscal position going forward? Why wouldn't we just work within Canada to address these issues?" Kaplan asks.

Opinion polling indicates that around 20% to 25% of Albertans plan to vote in favour of moving ahead with a binding separation referendum, with higher support among younger, rural and conservative voters.

Behind the separatist push is the belief that Alberta is misunderstood and overlooked by decision-makers in Ottawa. For decades, that sentiment fuelled a sense of "western alienation" in the prairie province.

Once a fringe movement, a number of factors pushed it to the forefront of Alberta politics.

There was anger over environmental and political pushback that killed proposed pipelines from landlocked Alberta to coastal waters.

A decade of Liberal government in Ottawa has also caused frustration in reliably conservative Alberta. And, in addition, there is also leftover distrust of the federal government over what some Albertans saw as excessive lockdowns during the Covid-19 pandemic.

Over the past year, separatist organisers held townhalls across the province to gauge interest from the public. They then launched a citizen-led petition to separate earlier this year, which got more than 300,000 signatures.

Smith, the premier, decided earlier this year she would authorise a vote.

Alberta is home to Canada's oil and gas sector, with oil reserves estimated to be the fourth-largest in the world. Crude oil is by far Canada's most profitable commodity, accounting for C$142bn in export value in 2025 alone.

Most of it is sold to refineries in the US.

The province has the highest GDP per capita in the country, and it contributes billions a year to the federal tax pool because of its strong economy.

It has not received any "equalisation" payments - money that so-called "have not", or less wealthy, provinces receive from the federal government - since 1965.

Calculations by Tegan Hill and Nathaniel Li, economists at the Fraser Institute think tank, show that Alberta's total net contribution to Ottawa since 2007 has been C$322bn, or an average of around $17bn per year.

"That's nearly four times that of British Columbia, more than four times Ontario," Hill tells the BBC. "The other seven provinces were net recipients, meaning Ottawa spent or transferred more money to those provinces than it collected."

Hill explains that the amount Alberta contributes to the rest of Canada is one of the main frustrations cited by those in favour of separation.

The sentiment, she says, is that: "We're paying to support these other provinces, and if we just went our own way, we could keep all that wealth for ourselves."

This belief is at the heart of the economic projections from the Alberta Prosperity Project, one of the main groups organising in favour of independence.

In its fiscal plan, released last year, external, they estimate Alberta will save up to C$47bn annually if it stops paying federal taxes.

The plan acknowledges that Alberta's costs would be higher if it were independent because it would have to pay for things like national defence and international diplomacy, estimating those costs to be up to C$31.6bn annually.

This would be in addition to paying for things Alberta as a province already covers, like healthcare and education, which cost around C$75bn.

After all its essentials and new expenses are paid for, the Alberta Prosperity Project estimates a surplus of C$24bn to C$46bn per year.

With all this extra money, proponents of separation argue Alberta could lower taxes on individuals by more than C$10,000 a year, build out its infrastructure or invest the surplus into the province's wealth fund.

But a number of economists argue their projections lack clarity and likely overestimate the windfall.

Hill of the Fraser Institute says one of the biggest drivers for economic decline is prolonged uncertainty, especially if the referendum doesn't put the issue to bed or if it ends up in a lengthy divorce from Canada.

"If someone doesn't know if Alberta is going to be a part of Canada or if it's going to go on its own way in the next couple years, in what world are they going to be putting their money in the province?" she asks.

Prime Minister Mark Carney often points to Brexit - the vote to separate Britain from the European Union - as a cautionary tale for Alberta.

The UK economy has taken a 6% hit from the effects of Brexit, according to one report published earlier this year. If Alberta's economy suffered a similar fate post-independence, its economy could shrink by C$62bn annually, according to one projection by Calgary-based economist Trevor Tombe.

This would also result in its workforce shrinking by 175,000, he estimated.

Wilson dismisses that comparison, arguing the "fundamental dynamics are completely different".

He says some of the projections by the stay side are all "doom and gloom", joking that the only possible negative they failed to include is "a large asteroid hitting Canada".

"We're a resource economy. We have leverage. We have products the world wants. That's why investment comes here, despite the constraints imposed by Ottawa," he says.
