In March 2018, Canada and 10 other jurisdictions in the Asia–Pacific region signed the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP or the Agreement). Since then, several jurisdictions have expressed an interest in acceding to the Agreement, and those that make a formal request to do so must complete the steps in the CPTPP’s accession process in order to accede. To date, the United Kingdom alone has acceded to the Agreement. Among the other jurisdictions that have requested accession, the process has formally started only for Costa Rica and Uruguay. In August 2026, a number of jurisdictions had either acceded to the Agreement, made a formal accession request or informally indicated an interest in acceding to the Agreement.
