Before Alberta talks independence, it needs to price the cost.
A border can be drawn with a line, but an economy cannot be separated nearly as cleanly.
This is the central lesson Alberta should take from Brexit. Modern economies are networks with suppliers, workers, infrastructure, capital, regulations and customers. The deeper the integration, the more expensive to unwind.
Tariff-free is not friction-free
Britain offers a useful case study because the UK and European Union ultimately negotiated a zero-tariff, zero-quota trade agreement. Yet British businesses still faced customs declarations, rules-of-origin requirements, regulations, new Value-Added Tax (VAT) treatment and border administration.
Tariff-free trade, in other words, is not frictionless trade. And friction has a cost.
The UK’s Office for Budget Responsibility (OBR) estimates that the post-Brexit trading relationship will leave long-run productivity ~4 percent lower than if Britain had remained in the EU, while imports and exports are each expected to be roughly 15 percent lower. Those figures are estimates, not settled fact, and Brexit’s effects cannot be separated cleanly from the pandemic, the war in Ukraine, or Britain’s pre-existing productivity problems.
The magnitude can be debated. The direction is harder to dismiss: adding barriers to an integrated economy carries a price.
The cost starts before the exit does
The more revealing lesson may be what happened before Brexit was implemented. The OBR estimates that roughly two-fifths of the productivity effect had occurred by the time the new trade agreement came into force, largely because uncertainty weighed on investment and capital.
Then there’s the administrative bill. Britain’s National Audit Office found that government departments spent £4.4 billion preparing for EU exit, including £1.9 billion on staffing and £1.5 billion on systems and infrastructure. At the peak, approximately 22,000 staff were working on exit preparations, before accounting for ongoing operating costs or the broader economic effects.
Alberta is not Britain but the cost structure is relevant
Alberta is not Britain, and Canada is not the European Union. The comparison should not be overstated. But the cost structure is relevant.
Alberta’s nominal GDP was ~$36 billion in 2024. That same year, it exported $70.6 billion in goods and services to other provinces. Its businesses operate inside a deeply integrated Canadian market of customers, workers, suppliers, financial institutions, railways, pipelines, and common regulatory systems.
Any serious economic case for Alberta separation therefore must account not only for what Alberta produces, but for what integration currently makes possible.
Five questions that need answers
- What new trade friction would separation create?
- What would uncertainty do to capital investment?
- What institutions and regulatory systems would have to be duplicated?
- What purchasing power, negotiating leverage and economies of scale would be lost?
- How much public money and executive attention would be diverted from productivity, infrastructure and innovation into the mechanics of separation?
As citizens, we should be asking political questions. But questions this consequential also demand economic answers.
“It began as a protest and ended as a consequence”
A few years ago, in Northern Ireland, a man described the Brexit vote to me as something that began as a protest and ended as a consequence. Voters who were angry and felt unheard seized a rare chance to be counted, he said — and only later did the scale of the economic damage come into focus, a burden he stated the next generation will spend decades navigating.
Supporters of separation should be able to show the baseline if Alberta remains in Canada, the annual cost of new friction and duplicated systems, the growth required to offset those costs, the time needed for benefits to exceed the transition expense — and what happens if the optimistic assumptions prove wrong.
The bottom line
Brexit does not tell Albertans how to vote. It does tell us something narrower and more useful: economic integration has measurable value, and unwinding it creates measurable costs.
Any credible case for independence must calculate both.
