Source page: https://www.palisade.email/research/canada-email-authentication-2026/ontario
Observed Ontario domains: 556
Rest-of-cohort comparator: 472
Municipal share of Ontario slice: 439/556 (79.0%)

Findings
- DMARC adoption: 413/556 (74.3%) in Ontario; 423/472 (89.6%) in the rest of the sourced Canadian cohort.
- Enforcement among DMARC publishers: 250/413 (60.5%) in Ontario; 216/423 (51.1%) in the rest of the sourced Canadian cohort.
- DMARC publishers without aggregate reporting: 90/413 (21.8%) in Ontario; 25/423 (5.9%) in the rest of the sourced Canadian cohort.
- SPF publishers with recursive lookup failures: 21/508 (4.1%) in Ontario; 9/418 (2.2%) in the rest of the sourced Canadian cohort.

Pitch leads
- Local: Ontario's complete municipal-directory slice exposes a reporting gap that is hidden by the national aggregate.
- Operational: Ontario DMARC publishers enforced more often while missing aggregate reporting more often.
- Standards: A numerator-and-denominator comparison that separates policy publication, enforcement and reporting.

Limitations
- This is a sourced organizational benchmark, not a representative sample of every Ontario organization or business.
- Ontario contributes the complete official municipal-directory slice, so composition differs materially from the rest of the Canadian cohort.
- Comparisons are descriptive and do not establish that geography or organization type caused a DNS configuration difference.
- Public DNS state does not prove compromise, delivery performance, phishing incidence or internal security maturity.
