Services matter most. Roughly four-fifths of the total GDP gains would come from liberalizing services sectors. This reflects their growing weight in the economy and their role as inputs into nearly all other activities. For instance, barriers in finance, telecommunications, transportation, and professional services, which are essential inputs for most businesses, ripple through the economy, raising costs well beyond the sectors where they originate.
Prioritization matters
Full liberalization will take time. That makes prioritization essential. The highest-impact reforms are not necessarily in sectors with the highest measured barriers, but in those with the greatest economic influence—sectors that are heavily traded across provinces and deeply embedded in input-output networks.
Finance, transport, and telecommunications stand out as enablers of economy-wide efficiency, innovation, and competition. Progress here would amplify returns elsewhere: making it easier to start and expand a business, improving labor mobility, and supporting investment in high-productivity activities. It would also strengthen Canada’s capacity to absorb external shocks. Our analysis suggests that even modest reductions in internal trade costs could help offset sizable adverse shifts in external trade conditions, underscoring the role of domestic integration as a resilience buffer.
Making federalism work for a single market
The challenge revolves around implementation and coordination. With the federal framework largely in place, further progress depends on making cooperative federalism work more effectively. Mutual recognition should become the default, with narrow and transparent exceptions—starting with professional licensing and credential recognition. Benchmarking and public reporting of internal trade barriers can sharpen accountability and sustain momentum. Federal leadership can continue to play a catalytic role through incentives, conditional funding, and convening power—while fully respecting provincial jurisdiction.
Canada has navigated complex federal-provincial reforms before. Internal market integration can follow in that tradition: pragmatic, incremental, and anchored in shared national gains.
A moment to act
Canada’s economic future will be shaped as much by how effectively it mobilizes its domestic market as by how it engages globally. The evidence is clear: internal barriers remain large, economically costly, and increasingly out of step with the needs of a modern, vibrant, service-intensive economy. Removing them offers one of the most powerful—and least fiscally costly—levers to raise productivity, strengthen resilience, and support inclusive growth.
The opportunity is now. The prize is large. Turning thirteen economies into one is no longer just an aspiration—it is an economic imperative.
