Mozilla names CIRA Canadian Shield the default DoH service for Canadian Firefox users

OTTAWA – July 8, 2021 – In the effort to enhance the privacy of as many Canadians as possible, CIRA is proud to announce that CIRA Canadian Shield has been chosen as the default DNS over HTTPS provider for Firefox users in Canada.

CIRA joins the Mozilla Trusted Recursive Resolver (TRR) Program and becomes the first organization to provide country-specific encrypted DNS services in the Firefox browser.

After just over a year in the market, and with more than 100,000 users, CIRA Canadian Shield serves more than 500 million queries each day, protecting the privacy and security of individuals and families across Canada.

Key facts

  • CIRA Canadian Shield will roll out to one per cent of Canadian Firefox users on July 20, gradually reaching 100 per cent of Canadian Firefox users in late September 2021.
  • The Private feed of CIRA Canadian Shield (DNS privacy with no malware blocking) will be the default resolver for Canadian Firefox users. Firefox users may switch to the Protected or Family feed by changing their default settings.
  • Polling data commissioned by CIRA indicates that 84 per cent of Canadians are at least somewhat concerned that businesses willingly share users’ personal data with third parties without consent. 
  • Since launch, CIRA Canadian Shield has experienced 100 per cent uptime, and its Protected feed has blocked approximately one malicious domain per user every day, protecting them from cyber-attacks.
  • CIRA Canadian Shield is built on a combination of public and private threat feeds, including those from our partners: Akamai, the Canadian Centre for Child Protection and the Canadian Centre for Cyber Security
  • To confirm CIRA’s commitment to privacy for its users, Deloitte LLP conducted a full privacy audit of CIRA Canadian Shield. The audit found that “CIRA Canadian Shield service is suitably designed to support the achievement of CIRA’s privacy commitments.” Read the auditor’s report summary.
