CPTPP enters into force between Canada and the UK on September 1, 2026

The UK’s trading relationship with Canada is set to receive a significant boost when the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) enters into force between the two countries on 1 September 2026. Canada has completed its domestic ratification process, meaning UK businesses will be able to use CPTPP preferences when trading with Canada from this date.

The new arrangement will operate alongside the existing UK–Canada Trade Continuity Agreement, giving businesses an additional preferential trading framework. For UK exporters, CPTPP can provide reduced or eliminated tariffs on eligible goods, depending on the product and the applicable tariff schedule. Businesses will need to check the relevant commodity code and rules of origin before claiming preference.

One particularly useful feature is CPTPP's cumulation provisions. Subject to the relevant rules, materials and components originating in other CPTPP countries can contribute towards the originating status of a UK product. This could benefit UK manufacturers with international supply chains, particularly those sourcing components or materials from countries such as Japan, Australia or Mexico before exporting finished goods to Canada.

CPTPP also provides opportunities beyond goods. The agreement contains commitments covering services, investment, investor-state dispute settlement, digital trade and government procurement, helping create a more predictable environment for UK companies looking to expand their presence in Canada and other CPTPP markets.
