What the CPTPP Deal Means for Canadian Businesses
The UK's entry into the CPTPP gives Canadian companies another framework for doing business in the UK market.
Canadian businesses can benefit from access to key UK services sectors, including distribution, construction and architecture. Eligible Canadian service providers can also receive treatment comparable to domestic providers in covered UK services markets.
The agreement also expands opportunities in government procurement. Canadian companies can access procurement opportunities involving public institutions at different levels of government in the UK, including regional and local authorities.
Canadian investors can also benefit from CPTPP protections that provide greater certainty, transparency and protection for investments in the UK.
Canada-UK Trade Gets a Wider Framework
The new CPTPP arrangement does not replace the existing Canada-UK Trade Continuity Agreement.
Instead, the two agreements work alongside each other. The CPTPP adds another set of trade rules and opportunities for Canadian and UK businesses while maintaining the existing bilateral trade framework.
Global Affairs Canada said the agreement can also support more integrated supply chains by providing businesses with a common set of rules across CPTPP markets.
Canada and the UK Already Have Strong Trade Links
The new agreement builds on a substantial economic relationship between Canada and the UK.
In 2025, the UK was Canada's largest trade partner in Europe and its fourth-largest merchandise trading partner globally. Canada-UK trade reached $56.6 billion during the year.
The UK was also Canada's second-largest services trading partner among countries, with services trade totaling nearly $24.7 billion in 2025.
These existing trade links give businesses in both countries an established base for taking advantage of the additional opportunities available under the CPTPP.
UK Businesses Gain Full CPTPP Access
The UK's accession also benefits British companies.
The UK government confirmed on September 1 that British businesses now have full access to the CPTPP trading bloc. Canada was the final CPTPP member to ratify the UK's accession, allowing UK businesses to access all 11 other CPTPP members.
The UK government says the bloc's combined economies are worth almost £13 trillion, including the UK.
For businesses operating between the UK and Canada, the agreement provides enhanced access to public procurement markets and new opportunities in goods and services.
Eligible UK business visitors to Canada can also benefit from easier business mobility rules under the CPTPP.
CPTPP Now Covers 12 Economies
With the UK's accession fully implemented, the CPTPP now includes 12 members: Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, Vietnam and the United Kingdom.
Global Affairs Canada says the expanded CPTPP covers more than 598 million people and represents 14.4% of global GDP.
The wider membership gives Canadian companies another route into international markets while strengthening Canada's trade links with the UK and the broader Indo-Pacific region.
What Happens Next for Canadian Businesses?
Canadian companies will now be able to assess where the new CPTPP provisions can complement their existing trade arrangements with the UK.
The biggest areas to watch include services, government procurement, investment and supply chains.
Businesses that already trade with the UK may find additional opportunities through the CPTPP, while companies that have not previously explored the UK market may have another reason to consider expanding internationally.
Bottom Line
The CPTPP accession protocol taking effect between Canada and the UK on September 1, 2026, marks an important step in the economic relationship between the two countries.
For Canadian businesses, the agreement provides additional opportunities across services, investment, government procurement and trade while complementing the existing Canada-UK Trade Continuity Agreement.
With the UK now fully integrated into the CPTPP, Canadian companies also gain access to a broader trade framework covering 12 economies and more than 598 million people.
