Introduction

Canada is a country built on trade, yet some of its most stubborn trade barriers sit inside its own borders. Provinces and territories regulate everything from trucking standards and professional licensing to alcohol distribution and public procurement, and differences in those rules can make selling a product or service across a provincial line almost as complicated as exporting it. The Agreement on Internal Trade was created to address that problem, and its successor, the Canadian Free Trade Agreement, continues the effort today.

For business leaders, the subject matters more than ever. Renewed tariff pressure from abroad has pushed governments to look again at what they can fix at home, and economists increasingly argue that a more integrated domestic market is one of the cheapest growth levers available. Understanding how the agreement worked, why it fell short and what has replaced it helps managers plan supply chains, hiring and expansion with fewer surprises.

In this article, we will discuss what the Agreement on Internal Trade is, why Canada needed it, how it operated, its limitations, the move to the Canadian Free Trade Agreement, the economic cost of internal barriers, the impact on businesses and supply chains, labour mobility, recent reforms, practical steps for organisations, and what the future may hold.

1- What Is the Agreement on Internal Trade?

Definition and Purpose

The Agreement on Internal Trade, usually shortened to the AIT, was an intergovernmental agreement signed in 1994 by the federal, provincial and territorial governments of Canada and in force from July 1995. Its stated aim was to reduce and eventually eliminate barriers to the free movement of persons, goods, services and investment within Canada, and to build an open, efficient and stable domestic market. In simple terms, it was a promise between governments that a business or worker approved in one jurisdiction should not face unnecessary obstacles when operating in another.

Legal Nature and Scope

The AIT was not a treaty with another country and it was not part of the Constitution. It was a political and administrative agreement among governments, which meant its power depended on each party's willingness to follow it. It set out general rules, such as non-discrimination between provinces, and then added sector chapters covering areas such as government procurement, investment, labour mobility, consumer-related measures and standards, agriculture and food, alcoholic beverages, transportation and energy. Because it covered only the sectors written into it, many activities, particularly in services, sat outside its protection.

Why the Name Still Matters

Although the AIT was replaced in 2017, the name remains widely used in business, law and policy discussions. Older contracts, procurement rules and regulatory decisions often refer to it, and many of the reforms that followed were designed to repair its weaknesses. Knowing the original agreement therefore makes it far easier to understand the current framework.

2- Why Canada Needed an Internal Trade Agreement

A Federation with Divided Powers

Canada's constitution divides authority between the federal government and the provinces, with the territories exercising delegated powers. Provinces control many of the rules that shape everyday commerce, including professional regulation, consumer protection, labour standards, much of transportation law and the sale of alcohol. Section 121 of the Constitution Act, 1867, which says goods from one province should be admitted free into the others, has historically been read narrowly by the courts, as a ban on tariffs rather than a guarantee of regulatory harmony. That left room for each province to develop its own approach.

How Differences Became Barriers

None of these differences were created to block trade. Most began as reasonable local choices. Over time, however, they accumulated into a patchwork. Trucking weight limits, labelling requirements, trade qualifications and procurement preferences varied from province to province, and a firm wishing to grow nationally often had to comply with a dozen sets of rules. The practical result was that interprovincial trade became more costly than the size of the shared market would suggest.

Barrier Type	Typical Example	Effect on Business
Product standards	Different labelling or packaging rules	Separate production runs and testing
Occupational licensing	Re-certification when moving provinces	Delayed hiring and lost earnings
Procurement preferences	Local suppliers favoured in tenders	Narrower competition and higher prices
Transport rules	Varying weight limits and permits	Extra permits and fragmented routes
Alcohol and food distribution	Provincial control of sales channels	Restricted access to regional markets

The Scale of the Market at Stake

The size of the prize helps explain why governments kept returning to the issue. According to Statistics Canada, interprovincial trade in manufactured goods reached $167.4 billion in 2024, while interprovincial trade in wholesale goods reached $562.5 billion. Those figures show that Canadian businesses already sell heavily to one another, which means that even small reductions in friction can produce large savings.

3- How the AIT Worked in Practice

The AIT relied on a set of shared principles rather than on a single central authority. Governments agreed to follow common rules, to resolve disputes through a defined process and to negotiate further liberalisation over time. Its main features can be grouped into five practical mechanisms.

1- Non-discrimination:

Provinces agreed not to treat goods, services or investors from other provinces less favourably than their own. In practice, this meant a Manitoba supplier should not be excluded from a contract in Ontario simply because of its origin, although exceptions weakened the rule.

2- Right of entry and exit:

Businesses and workers were meant to move between provinces without being forced to establish a local presence merely to compete. This principle aimed to stop governments from using residency or office requirements as a quiet barrier.

3- Legitimate objectives:

Governments could keep measures that protected health, safety or the environment, provided they were not a disguised barrier to trade. This balanced market access against the public interest, but the test for what counted as legitimate was often argued over.

4- Reconciliation of standards:

Governments committed to work towards making differing regulations compatible, so that a product or qualification approved in one province could be accepted in others. Progress depended on negotiation, and results were uneven.

5- Dispute resolution:

A formal process allowed governments, and in some cases private parties acting through them, to challenge measures believed to breach the agreement, using consultation and panels. The process created a route for complaints, although enforcement proved difficult.

Procurement deserves special mention. Government purchasing is a large market, and rules that favour local suppliers can shut out efficient competitors elsewhere in the country. The AIT's procurement chapter set thresholds above which contracts were meant to be open to suppliers from across Canada, and it encouraged transparent tendering. Organisations that bid for public contracts therefore needed sound governance, clear documentation and a good grasp of their compliance obligations.

4- Limitations of the AIT

Despite good intentions, the AIT struggled to deliver the open domestic market its authors had imagined. Economists and business groups pointed to five recurring weaknesses.

1- A positive-list coverage model:

The AIT applied mainly to sectors and measures listed in its chapters, so large parts of the economy, including many services, were not covered. Businesses could not assume that a barrier was unlawful simply because it hindered trade.

2- Numerous exceptions:

Governments carried long lists of exceptions that preserved local preferences. Over time these exceptions became a major reason for the slow pace of liberalisation.

3- Weak enforcement:

Dispute resolution existed, but panels had limited powers and governments often had little incentive to accept findings against themselves. Remedies were slow, and few cases produced lasting change for ordinary businesses.

4- Slow reconciliation:

Aligning regulations demanded long negotiations across thirteen jurisdictions. Priorities changed, political attention drifted and many technical differences remained.

5- Limited visibility:

Few small firms understood their rights under the agreement, and there was little systematic public reporting on barriers, so problems often went unmeasured.

These weaknesses did not mean the AIT achieved nothing. It established the principle that internal barriers were a legitimate subject for national policy, and it created institutions and habits of cooperation that later reforms could build on. But by the middle of the 2010s, governments largely agreed that a stronger framework was needed.

5- From the AIT to the Canadian Free Trade Agreement

A New Framework in 2017

The Canadian Free Trade Agreement, or CFTA, came into force on 1 July 2017 and replaced the AIT. Negotiated by the federal, provincial and territorial governments, it kept the goal of an open domestic market but changed how the rules were built. The most important shift was the move to a negative-list approach: the agreement applies to all sectors and measures unless a government has specifically listed an exception. That reverses the burden of proof and makes it clearer when a barrier needs justification.

Regulatory Cooperation and Dispute Settlement

The CFTA also gave regulatory cooperation a more formal home. A dedicated body, the Regulatory Reconciliation and Cooperation Table, was set up to help governments find common ground on differences in regulation. In addition, the agreement strengthened dispute resolution, including clearer procedures for complaints raised by businesses and individuals, and it put more emphasis on transparency, with governments expected to review their exceptions over time.

What Remained Unfinished

The CFTA was a clear improvement but not the end of the story. Exceptions remained numerous, particularly in sectors such as agriculture, alcohol and some services, and implementation relied heavily on political will. For many firms, the agreement's promise was real, but its day-to-day effect depended on whether individual provinces reduced their remaining carve-outs. Smaller firms in particular often lacked the resources to check which exceptions applied to them, so reform on paper did not always translate into savings on the ground.

6- AIT vs CFTA: Key Differences

A side-by-side comparison shows how far the framework has moved since the 1990s.

Feature	Agreement on Internal Trade	Canadian Free Trade Agreement
Entry into force	July 1995	1 July 2017
Coverage model	Positive list of covered sectors	Negative list: all sectors unless excepted
Exceptions	Extensive, with limited review	Listed and subject to review
Regulatory cooperation	Reconciliation through negotiation	Dedicated table and structured work
Dispute resolution	Panels with limited remedies	Strengthened process with clearer complaint routes
Transparency	Limited public reporting	Greater emphasis on openness

The table shows an evolution rather than a revolution. The core ambition is unchanged, but the CFTA's structure makes it easier for businesses to challenge barriers and harder for governments to rely on unlisted rules. For a manager, the practical gain is predictability: under a negative list the question becomes whether a measure has been excepted, rather than whether it happens to be covered.

7- The Economic Cost of Internal Trade Barriers

Barriers as a Hidden Tax

Economists often describe internal barriers as a tax that governments impose on themselves. Unlike a tariff, the cost does not appear as revenue anywhere; it shows up as duplicated paperwork, delayed shipments, higher prices and missed opportunities. Because the barriers apply inside the country, they weigh most heavily on small and medium-sized enterprises, which lack the legal teams that large firms use to navigate multiple regimes.

What the Research Says

A widely cited 2019 working paper by Jorge Alvarez, Ivo Krznar and Trevor Tombe, published by the International Monetary Fund, estimated that fully liberalising internal trade in goods could raise GDP per capita by about 4 per cent. The authors also argued that federal, provincial and territorial governments needed to work together to reduce restrictions, and that the Canadian Free Trade Agreement offered a base to build on.

More recent work points in the same direction. According to the International Monetary Fund, policy-related barriers within Canada amount to the equivalent of a tariff of about 9 per cent nationally, and deeper integration could raise real GDP by nearly 7 per cent over the long term. The analysis also found that costs fall most heavily on services and on smaller provinces and northern territories.

A Resilience Buffer

Beyond headline growth numbers, a more integrated market offers insurance. When external trade becomes less predictable, a firm that can sell easily across provincial lines has more options. Greater internal integration can therefore support resilience as well as efficiency, a point that has become central to recent policy debate.

8- Impact on Businesses and Supply Chains

Cost, Complexity and Competition

For individual firms, internal barriers show up in everyday decisions. A food producer may need different labels for different provinces. A construction contractor may find that a licensed tradesperson cannot work across a provincial line without further approval. A distributor may keep several regional warehouses simply because regulatory differences make a single national hub impractical. Each of these choices adds cost that competitors in more integrated markets do not bear.

Supply Chain Design

Supply chain leaders feel these effects most directly. Fragmented rules can push companies to source locally even when a supplier in another province would be cheaper or more reliable, and they can undermine efforts to diversify suppliers. A more open internal market widens the supplier pool, which supports resilience and bargaining power. This is why procurement strategy and regulatory awareness now belong in the same planning conversation.

Business Function	Effect of Barriers	Benefit of Integration
Procurement	Narrower supplier pool and local preferences	Wider choice and stronger negotiation
Logistics	Duplicated permits and regional warehousing	Simpler national distribution
Human resources	Re-licensing and slower hiring	Faster staffing across regions
Compliance	Multiple rule sets to monitor	Fewer and more consistent obligations
Sales and marketing	Product variation by province	Easier national launches

Compliance as a Competitive Skill

Because the framework is still evolving, compliance teams must track which rules have changed and which exceptions remain. Firms that understand customs, trade documentation and regulatory risk can expand faster and avoid costly delays. Skills built for international trade, such as classification, documentation and risk assessment, transfer well to managing internal trade rules.

9- Labour Mobility and Professional Recognition

Labour mobility is one of the most visible parts of the internal trade agenda. Many occupations are regulated provincially, so a nurse, engineer or electrician certified in one province may face fresh assessments, fees or waiting periods in another. For workers, this slows careers and family moves. For employers, it complicates hiring and leaves vacancies open longer, especially in regions with skills shortages.

Small and rural employers are often affected most. A regional hospital, a growing construction firm or a municipal utility may depend on recruiting from outside its province, yet lack the administrative capacity to manage several licensing processes. Simpler recognition rules would therefore help employers in smaller provinces and northern communities, which already compete for scarce skilled workers.

The agreements have tried to address this through mutual recognition: the principle that a person certified to practise in one province should be allowed to practise in others without repeating the process, subject to limited exceptions. Progress has been uneven, partly because regulators hold decision-making power and partly because professional bodies have different standards and traditions.

For HR leaders, this means treating credential recognition as a workforce planning issue. Organisations that hire across provinces benefit from understanding which professions have streamlined pathways, which still require additional assessment and how long each step typically takes. Clear onboarding plans reduce the risk of qualified staff being unable to work while paperwork is completed.

10- Recent Reforms and Momentum

Pressure to act intensified in 2025, when renewed tariff threats from the United States prompted governments across Canada to ask what they could fix at home. Federal and provincial governments introduced legislation and policy changes aimed at removing barriers, with a particular focus on mutual recognition of goods and professional credentials. The federal Free Trade and Labour Mobility in Canada Act was among the most prominent measures, and several provinces announced their own commitments to accept products and qualifications approved elsewhere in the country.

These steps show a notable change in political mood. Internal trade, once treated as a technical issue for officials, is now discussed as a matter of economic security. At the same time, analysts caution that announcements are not the same as outcomes. Exceptions remain, implementation differs between provinces, and sectors such as food, alcohol and some regulated services have often been treated more cautiously.

What to Watch Next

Three developments deserve attention over the coming years. The first is whether governments shorten their exception lists, since each removal widens the market covered by the agreement. The second is how consistently regulators apply mutual recognition in practice, because rules on paper only help when licensing bodies and inspectors follow them. The third is whether services, which make up the largest share of economic activity and face the highest barriers, receive the same attention as goods. Businesses that monitor these three signals will be able to anticipate change rather than react to it.

Transparency is likely to determine whether momentum lasts. Benchmarking and regular public reporting on barriers can sharpen accountability and help sustain reform. Policy analysts and public servants who design and evaluate these measures need strong skills in policy analysis, stakeholder engagement and impact assessment.

11- Practical Steps for Businesses

Whatever the pace of reform, organisations can act now to reduce the cost of internal barriers and prepare for further change. Five steps are particularly useful.

1- Map your interprovincial exposure:

List where goods, services and staff cross provincial lines, and note which rules apply in each location. A simple matrix of products, provinces and regulatory requirements often reveals duplicated costs that nobody had measured.

2- Review procurement and supplier strategy:

Check whether local preferences in your own sourcing policies limit competition, and test whether suppliers in other provinces could offer better value or resilience. Public sector bidders should also review how tender rules apply to them.

3- Track exceptions and reforms:

Assign someone to monitor changes to the CFTA, provincial legislation and regulator announcements. Regular summaries for managers keep decisions up to date and prevent costly surprises.

4- Plan credential recognition early:

When hiring across provinces, identify the recognition process before the offer is made, and build realistic timelines into onboarding so that new colleagues can start work promptly.

5- Use available complaint channels:

If a barrier appears to breach the agreement, find out whether a government, trade association or the dispute process can raise the issue. Documenting costs and delays strengthens any case.

Training matters as well. Operations and logistics teams that understand regulatory risk, supplier management and negotiation are better placed to turn a more open market into a competitive advantage rather than a compliance burden.

12- Conclusion

The Agreement on Internal Trade began as an attempt to turn a collection of provincial markets into one national economy. It set the principle, created institutions and started a conversation that continues today, but its limited coverage, numerous exceptions and weak enforcement kept results modest. The Canadian Free Trade Agreement improved the design by adopting a negative-list approach, strengthening cooperation and clarifying dispute processes, yet the work is still unfinished.

For businesses, the lesson is practical. Internal barriers are a real cost, the evidence suggests that removing them could deliver significant economic gains, and recent reforms suggest governments are more willing than before to act. Organisations that understand the rules, monitor change and invest in the skills to manage compliance and sourcing will be best placed to benefit as Canada moves, step by step, towards a more unified domestic market.
