CSIO Recognizes Six Insurers for Achieving Compliance Certification

(Toronto, ON – September 2, 2026) – CSIO is pleased to congratulate Howick Mutual Insurance Company, Maple Mutual Insurance Company, Sandbox Mutual Insurance, Stanley Mutual Insurance Company, Westminster Mutual Insurance Company, and Yarmouth Mutual Insurance Company on achieving CSIO’s Compliance Certification.

The CSIO Compliance Certification recognizes insurers that have eliminated Z-codes (non-standard coverage codes) from their data exchange with brokers and use only CSIO Standard codes. By adopting standardized codes, insurers help improve data quality and consistency across broker workflows, supporting more accurate reporting, operational efficiency, and a better broker experience.

“Congratulations to Howick, Maple, Sandbox, Stanley, Westminster and Yarmouth on achieving CSIO Compliance Certification,” said Kathryn Sinclair, President & CEO of CSIO. “This certification reflects their commitment to using industry standards to improve the accuracy and consistency of data exchanged between insurers and brokers. As more insurers align with CSIO Standards, brokers benefit from straightforward data, more reliable workflows, and a better experience for the customers they serve.”

CSIO works with insurers to support the transition from non-standard Z-codes to CSIO Standard codes, helping ensure that information is exchanged consistently across the industry. Insurers can also request new coverage codes through CSIO’s maintenance request process. Submitted requests are reviewed by CSIO’s National Standards Working Group and once approved, can be programmed immediately into insurers’ systems, eliminating the need for Z-codes.

Achieving Compliance Certification is an important step in strengthening industry-wide adoption of CSIO Standards. Greater consistency in the way data is exchanged helps reduce manual work, improve reporting and data quality, and create more streamlined digital workflows for brokers and insurers.
