Subject: Telecom Decision CRTC 2022-264 – Changes to the Canadian Data Interchange Guidelines and migration to Transport Layer Security 1.3 – Scheduling and testing TLS 1.3
Dear Recipient,
On 26 September 2022, in Telecom Decision CRTC 2022-264 (TD 2022-264), the Commission approved the Business Process Working Group’s (BPWG) consensus Task Identification Form (TIF) report BPRE096b and the updated Canadian Data Interchange Guideline. Accordingly, the Commission directed telecommunications service providers to migrate to the use of Transport Layer Security 1.3 for exchanging data over Application Statement 2 links by 30 June 2023.
On 5 May 2023, the BPWG Chairperson sent a letter to inform the Commission that several trading partners are not ready to schedule or test TLS 1.3. Your company has been identified as one of those trading partners.
In order to ensure compliance with the Commission’s determinations, your company must expedite its preparation for testing. It is important that all trading partners implement TLS 1.3 by the 30 June 2023 deadline in order to avoid a disruption of services that would impact Canadians in relation to local number portability, PIC/CARE, directory listings and the exchange of billing and collection data.
Please note that, should your company wish to reply to the Commission on this matter, this information will be placed on the public record unless your company requests that certain information remain confidential. As set out in section 39 of the Telecommunications Act and in Broadcasting and Telecom Information Bulleting CRTC 2010-961, Procedures for filing confidential information and requesting its disclosure in Commission proceedings, person may designate certain information as confidential. A person designating information as confidential must provide a detailed explanation on why the designated information is confidential and why its disclosure would not be in the public interest, including why the specific harm that would likely to result from the disclosure would outweigh the public interest in disclosure. Furthermore, a person designating information as confidential must either file an abridged version of the document omitting only the information designated as confidential or provide reasons why an abridged version cannot be filed.
Yours sincerely,
