The future of data flows between the United Kingdom and the European Union in a post-Brexit world aren\u2019t at the top of the agenda in negotiations between the two sides, but a failure to reach an agreement could have a significant impact on trade. The impasse centers on concerns by EU courts that the UK\u2019s surveillance laws that allow for \u201cgeneral and indiscriminate\u201d bulk collection of data are at odds with the EU\u2019s data-protection rules. Meanwhile, provincial governments in Canada are so concerned about the shortcomings of the country\u2019s federal data-protection legislation that they\u2019re preparing to go their own way to meet the requirements of the EU\u2019s sprawling General Data Protection Regulation.
